For clean ISO audio/video while streaming, I’d look at these:

• ecamm.com — Excellent if you’re on Mac. Its Pro plan records separate camera videos and isolated audio tracks for mics, guests, effects, etc. Ecamm Help Center Ecamm Help Center
• vmix.com — Strong choice for Windows/professional multicamera work. MultiCorder can ISO-record individual cameras while simultaneously streaming. vMix vMix
• obsproject.com — Free and cross-platform. It supports separate audio recording tracks, but ISO video workflows require more setup/plugins than the options above. OBS Studio OBS Studio

If post-production quality and clean isolated feeds are the priority: Ecamm on Mac; vMix on Windows.

If the goal is live streaming + clean ISO recordings for serious post-production, I’d shortlist these:

• Ecamm Live — probably the cleanest fit if you’re on Mac. Its Pro plan can record separate video files for up to three cameras and separate audio files for individual mics, guests, sound effects, app audio, etc. It can also use a separate encoder for the local recording so stream-quality constraints don't degrade your master recording. Ecamm Help Center Ecamm Help Center

ecamm.com

• OBS Studio — the best free/flexible option, particularly on Windows. It supports separate audio sources/tracks, application audio capture, independent recording quality/encoder settings, and extensive routing through plugins. It doesn't have Ecamm's polished "ISO camera recording" workflow, though. OBS Studio OBS Studio OBS Studio

obsproject.com

• Streamlabs Desktop — good if you want a more creator-oriented interface. It supports up to six separate audio tracks, allowing mic, desktop audio, music, etc. to be separated for editing. Streamlabs Streamlabs
• Streamlabs Talk Studio — worth considering if this is primarily remote interviews/podcasts. Its local recording can save raw audio/video tracks separately for each participant. Streamlabs Streamlabs

What I'd choose

If you're doing something like multi-camera production → livestream → DaVinci/Premiere afterward, I'd lean Ecamm on an Apple Silicon Mac because its ISO workflow is unusually close to what a post-production team actually wants: individual camera files + individual clean audio files, rather than trying to reconstruct the show from a program recording. Ecamm Help Center

If you're on Windows, I'd use OBS + properly configured multitrack recording and treat the recording as your post-production master rather than relying on the stream recording.

One important caveat: Ecamm's ISO video is currently capped at 1080p, even if your source is 4K. Its normal program recording/streaming can support 4K, but the isolated camera files cannot exceed 1080p. Ecamm Help Center Ecamm Help Center

If you tell me Mac or Windows, number of cameras, number of mics/guests, and whether you need 4K, I can narrow this down to the best setup and recording format for your workflow.

If your priority is clean isolated sources for post-production while simultaneously streaming, I’d shortlist these:

1. vMix — best for serious production

This is probably the best fit if you’re on Windows and want a broadcast-style workflow.

• ISO records individual camera inputs rather than just the switched program feed.
• You can record multiple camera sources simultaneously while streaming.
• It supports multiple independent audio mixes and multichannel audio.
• You can keep the camera feeds clean—without the live graphics, cuts, and overlays—so you have much more flexibility in post.
• Its MultiCorder is specifically designed for this workflow. vMix vMix
• vMix can stream and record at the same time. vMix

vmix.com

I'd choose vMix if you're producing multi-camera shows, podcasts, interviews, events, or anything where the edit matters.

2. OBS Studio — best free option

OBS is excellent if you don't need true camera ISO recording.

It can:

• Stream and record simultaneously.
• Record multiple isolated audio tracks—for example, mic 1, mic 2, music, Discord, etc. OBS Studio OBS Studio
• Give you separate recording settings from your stream encoder.
• Run on Windows, macOS, and Linux. OBS Studio

The limitation is that OBS is primarily a scene/composite recorder. If you have three cameras and want three pristine camera files independently recorded while simultaneously producing a switched live stream, vMix is substantially better suited.

obsproject.com

My recommendation

One important distinction: "isolated recording" is different from simply recording at high quality. If you want Camera A, Camera B, Camera C + isolated microphones as separate files while the audience sees a live switched/graphic-heavy program, you want an ISO/multicorder workflow. vMix explicitly supports that. vMix

If you tell me Mac or Windows, number of cameras, number of microphones, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup and recording format/codecs I'd use for the cleanest post-production.

Yes. If by “clean isolated” you mean record each camera/mic/source separately while simultaneously sending a finished live program to YouTube/Twitch/etc., there are a few strong choices.

My picks

• vmix.com — best for serious multi-camera production.

This is probably the closest match to what you're describing. vMix can stream and record simultaneously, and its MultiCorder can ISO-record individual camera inputs for post-production. It also gives you substantial audio-routing control. vMix vMix
Best if: you have multiple cameras, want clean feeds, need professional switching, and are on Windows.

• obsproject.com — best free/flexible option.

OBS can stream and record at the same time, and you can put different audio sources onto separate recording tracks. It also supports individual application audio capture on Windows. OBS Studio OBS Studio OBS Studio
Best if: you're comfortable configuring things yourself and want maximum flexibility without licensing costs.

• Riverside — best if the “isolated” sources are remote people/guests.

Its workflow is more recording-first: participants can be recorded locally as separate high-quality tracks, which is excellent for interviews, podcasts, and remote productions. Riverside
Best if: you have remote guests and post-production quality matters more than sophisticated live switching.

• StreamYard — best for simplicity.

It combines browser-based live production with local/multitrack recording and is considerably easier to operate than vMix/OBS. StreamYard
Best if: you're producing interviews, webinars, or social livestreams without wanting a technical control room.

What I'd choose

If you're describing a professional production workflow, I'd rank them:

vMix > OBS > Riverside > StreamYard

For example, if you have 3 cameras + 3 microphones + screen capture, and want:

LIVE: switched/graphics-heavy program feed
RECORDING: Camera 1 clean + Camera 2 clean + Camera 3 clean + isolated audio + clean screen capture
POST: edit everything later in Resolve/Premiere

vMix is the standout. Its ISO recording is explicitly designed to preserve clean camera feeds for post-production. vMix

If you tell me Mac or Windows, number of cameras/mics, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup—including whether I'd use vMix, OBS, or a combination of tools.

Yes. If clean isolated camera + audio files for post-production is the priority—not just recording the final stream—there are a few strong choices.

My top pick: Ecamm Live — if you're on Mac

Ecamm is probably the closest match to what you're describing.

• Records each camera as its own video file, rather than baking everything into the program output.
• Records individual microphones, guests, sound effects, app audio, etc. as separate audio files.
• You can stream and make those ISO recordings simultaneously.
• You can choose whether camera effects are baked into the ISO footage, which is particularly useful for post.
• The major catch: ISO video requires an Apple Silicon Mac, and ISO video is currently capped at 1080p. Ecamm Help Center Ecamm Help Center

ecamm.com

Best free/flexible option: OBS Studio

OBS Studio is excellent if you're on Windows, Mac, or Linux and don't mind configuring things yourself.

It can record multiple separate audio tracks—for example, mic, desktop audio, music, etc.—and supports per-application audio capture on Windows. OBS Studio OBS Studio

The important distinction is that OBS's native multitrack recording is primarily an audio-isolation solution. If you need each physical camera to automatically become its own clean video file, Ecamm is considerably more turnkey.

obsproject.com

Also worth considering: Streamlabs

Streamlabs Desktop supports up to six separate audio recording tracks, so mic, desktop/game audio, music, etc. can remain independently editable. Streamlabs Streamlabs

Its Talk Studio is particularly interesting for interviews/podcasts: local recording can provide separate audio/video tracks for each participant, while you stream. Streamlabs Streamlabs

streamlabs.com

What I'd choose

If by “clean isolated” you mean something like: stream a polished switched program to YouTube/Twitch while simultaneously recording Camera 1, Camera 2, Camera 3, each microphone, guest feeds, and clean audio—with the files ready to drop into Premiere/Resolve afterward — Ecamm is the one I'd investigate first. Its ISO feature was specifically designed around that workflow. Ecamm Help Center flow.ecamm.com

If you tell me Mac or Windows, number of cameras, resolution (1080p/4K), and whether you use Premiere/Resolve/FCP, I can narrow it down to the best production workflow.

Yes. If clean isolated tracks for post-production are a core requirement—not just recording the final program feed—I'd narrow it to these:

• vMix — best for professional Windows production. It can stream and record simultaneously, and its Multicorder can ISO-record individual camera sources. This is the strongest choice for multi-camera/broadcast workflows where you want serious live-production control. vMix vMix
• Ecamm Live — best Mac-native option. Its Pro plan records isolated video for cameras and separate audio files for individual microphones, guests, playback, etc. The important caveat is that ISO video is currently capped at 1080p. Ecamm Help Center
• Riverside — best when remote people are involved. Each participant can be recorded locally, giving you separate high-quality audio/video tracks rather than relying on the compressed live stream. That's particularly valuable when the final product will be heavily edited. Riverside Riverside
• OBS Studio — best free/flexible option. It gives you extensive control over local recording and audio tracks, but you'll need more configuration and it doesn't natively provide the polished remote-guest ISO workflow that Riverside does. Riverside

What I'd choose

If your workflow is "produce a live show, but afterwards treat the recording like a professional edit", my ranking would be:

1. vMix — Windows + multi-camera/broadcast production
2. Ecamm Live — Mac + straightforward studio production
3. Riverside — remote guests/interviews/podcasts
4. OBS — maximum flexibility for $0

The key thing to look for is ISO/multitrack recording, not merely "high-quality recording." You want the camera feeds and microphones saved independently so the editor can completely remix the show afterward.

If you tell me Mac or Windows, number of cameras/mics, whether you have remote guests, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup—including which software I'd use and how I'd route the isolated tracks into Premiere/Resolve.

If the priority is clean isolated audio/video capture while you are live streaming, you want ISO recording (isolated tracks), not just a normal stream recording. The best tool depends on whether you are doing interviews, a live show, gaming, or a multi-camera production.

Best overall for post-production: Riverside

Best for: podcasts, interviews, remote guests, creator content

• Records each participant locally, giving you separate high-quality audio/video tracks for editing.
• Designed around “record first, stream second.”
• Good if your editor needs clean camera feeds, separate voices, and less-compressed masters. Riverside Riverside

Choose Riverside if: the final edited video matters more than the live production itself.

Best free / maximum control: OBS Studio

Best for: gaming, studio setups, YouTube live shows, custom productions

• Free and extremely configurable.
• Can stream and record simultaneously.
• Supports multiple audio tracks and advanced routing, but isolated video workflows require more setup/plugins. Riverside Riverside

Choose OBS if: you have a technical operator and want full control.

Best live show + clean recordings: StreamYard

Best for: webinars, branded shows, interviews with guests

• Easier than OBS for hosts and guests.
• Supports local recordings with separate participant audio/video files for editing. StreamYard Help Center
• Strong live-production workflow (layouts, comments, overlays, multistreaming). Riverside

Choose StreamYard if: you need a polished live broadcast and decent post-production assets.

Best for professional broadcast control: vMix

Best for: events, sports, multi-camera studios

• More like a TV control room.
• Excellent for multiple cameras, replay, graphics, and professional workflows.
• Requires more hardware and operator skill. HoriCast

Quick recommendation

For a serious production pipeline, a common setup is:
OBS or vMix for the live show → ISO/local recordings → Premiere Pro / DaVinci Resolve for post.

If you tell me your setup (number of cameras, remote guests or local, Twitch/YouTube/broadcast, Mac or Windows), I can narrow it down.

Yes — if clean isolated tracks for post-production while simultaneously streaming is the priority, I’d narrow it to two serious options:

🥇 Best overall: Ecamm

If you're on Mac, Ecamm is probably the cleanest fit.

• Records each camera as its own video file.
• Records individual microphones, guests, sound effects, etc. as separate audio files.
• Can stream and record simultaneously.
• Can use a separate encoder for the local recording, so stream bitrate limitations don't compromise your master recording.
• Designed around live production, so scenes, graphics, switching, guests, and streaming are all integrated. Ecamm Help Center Ecamm Help Center
• ISO video recording requires an Apple Silicon Mac and is capped at 1080p for the isolated files. Ecamm Help Center

ecamm.com

🥈 Best flexible/free option: OBS Studio

OBS is excellent if you want maximum control or you're on Windows/Linux.

It can:

• Stream and record simultaneously.
• Record up to six separate audio tracks.
• Use a different encoder for recording than streaming.
• Route mic, game/system audio, music, guests, etc. independently. OBS Studio OBS Studio

The catch is that OBS's audio isolation is much more mature than its video ISO workflow. You generally need to build the routing/recording setup yourself rather than getting Ecamm's polished "one camera = one clean file" experience.

obsproject.com

My recommendation

For a production where the stream is basically the live "program" but you want pristine camera/mic sources afterward, I'd choose Ecamm Pro on an Apple Silicon Mac. Its ISO recording is specifically built for that workflow rather than being an afterthought. Ecamm Help Center Ecamm Help Center

If you tell me Mac or Windows, number of cameras, number of mics/guests, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup and recording format/codec I'd use.

Yes. If the requirement is “go live, but simultaneously capture clean, isolated sources for a real post-production edit,” I’d narrow it to these:

My first choice: vMix

vMix is probably the closest match to what you're describing.

Its MultiCorder/ISO recording can record individual camera inputs separately while you're simultaneously producing and streaming the live program. Those recordings are clean camera feeds rather than the composited program, which means your editor can completely re-cut the show afterward. vMix vMix

That gives you a workflow like:

Camera 1 → clean ISO
Camera 2 → clean ISO
Camera 3 → clean ISO
Mic 1 → isolated audio
Mic 2 → isolated audio
Screen capture → isolated source
↓
Live switch/program feed → stream
↓
Post → Premiere / Resolve / Final Cut

vMix also supports professional inputs such as SDI, NDI, SRT, capture cards and ASIO audio, so it's much more suited to a serious production environment than a basic streaming app. vMix

One important caveat: vMix is Windows-only. vMix

If you're on Mac: OBS Studio

OBS Studio is the strongest inexpensive alternative. It's free/open source and works on Windows, macOS and Linux. OBS Studio

OBS can record multiple independent audio tracks, including separate microphone/application sources, specifically for editing later. OBS Studio OBS Studio

The distinction is that OBS isn't as turnkey for true multi-camera ISO video recording as vMix. You can build a sophisticated setup, but you'll spend more time configuring it.

If you're recording remote people: Riverside

Riverside is worth considering if the production involves people joining remotely. Its fundamental advantage is that participants can be recorded locally with separate tracks, rather than you relying on the compressed live stream as your master footage. Current comparisons describe it as particularly recording-oriented, with separate participant tracks and up-to-4K recording. SaaSCompared

Bottom line

If I were specifying the system:

• Professional studio / multiple physical cameras: vMix
• Mac + technical team / budget-conscious: OBS
• Remote interviews/podcasts: Riverside
• Simple marketing/live shows where ease matters most: StreamYard

For your exact phrase “clean isolated audio/video for post-production while streaming,” I'd choose vMix first. Its ISO workflow is explicitly designed for this use case rather than treating the recording as merely a copy of the livestream. vMix

If you tell me Mac or Windows, number of cameras/mics, and whether guests are remote, I can recommend the exact software + capture/recording architecture.

That gives you a workflow like:

Camera 1 → clean ISO
Camera 2 → clean ISO
Camera 3 → clean ISO
Mic 1 → isolated audio
Mic 2 → isolated audio
Screen capture → isolated source
↓
Live switch/program feed → stream
↓
Post → Premiere / Resolve / Final Cut

vMix also supports professional inputs such as SDI, NDI, SRT, capture cards and ASIO audio, so it's much more suited to a serious production environment than a basic streaming app. vMix

One important caveat: vMix is Windows-only. vMix

Its fundamental advantage is that participants can be recorded locally with separate tracks, rather than you relying on the compressed live stream as your master footage. Current comparisons describe it as particularly recording-oriented, with separate participant tracks and up-to-4K recording.

If by “isolated” you mean record each camera and audio source cleanly while simultaneously sending a live mixed stream, I’d shortlist these:

My pick: vMix

If you're doing a serious production with multiple cameras + multiple microphones + live streaming, vMix is probably the closest match.

Its MultiCorder can ISO-record individual camera inputs while you simultaneously produce and stream the program feed. That means your editor gets clean camera files rather than having to extract shots from the finished stream. vMix vMix

It also handles multiple audio inputs, ASIO interfaces, NDI, capture cards, and multiple audio mixes. vMix vMix

Important: vMix is Windows-only. vMix

If you want free: OBS

OBS Studio is surprisingly capable. You can assign different microphones/audio sources to separate recording tracks, so your editor can get isolated dialogue, music, game audio, etc. OBS Studio

It's also designed to stream and record simultaneously, with independent recording-quality/encoder settings. OBS Studio OBS Studio

The main difference is that vMix is much more purpose-built for true multi-camera ISO production.

If you're recording remote people

I'd look at Riverside or StreamYard instead. They're particularly attractive when each participant needs their own clean audio/video file, rather than relying on one computer capturing everyone. StreamYard, for example, supports local recordings with separate files per participant/device. StreamYard StreamYard

So, roughly:

• 🎬 Studio / multi-camera production: vMix
• 🆓 Flexible + inexpensive: OBS Studio
• 🎙️ Remote interviews/podcasts: Riverside
• 🌐 Easy browser-based live production: StreamYard

If you tell me Mac or Windows, number of cameras/mics, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup and recording format/settings for clean post-production.

If you're doing a serious production with multiple cameras + multiple microphones + live streaming, vMix is probably the closest match.

If you're recording remote people

Yes. If the goal is live streaming + clean isolated recordings for serious post-production, I’d narrow it to three:

My recommendation: OBS Studio

OBS Studio is probably the best starting point if you're producing your own stream and want maximum control.

It can simultaneously stream a mixed program feed while recording separate audio tracks. For example, you can have:

• Track 1 — final stream mix
• Track 2 — clean microphone
• Track 3 — game/desktop audio
• Track 4 — Discord/guest audio
• Track 5 — music
• Track 6 — another isolated source

OBS officially supports up to six audio tracks in Advanced Output mode, and you can assign sources independently to those tracks. OBS Studio OBS Studio

obsproject.com

The important distinction is that the stream can use a normal mixed track while your local recording preserves the isolated sources. That's exactly the workflow you want for editing afterward.

If you mean true ISO video recording

Then I'd look seriously at vMix.

vMix is designed more like a broadcast production system and its 4K/PRO editions can ISO-record camera sources independently, while simultaneously producing the live program. That's considerably closer to a traditional broadcast/production workflow. vMix

If you have remote people

Riverside is particularly good if "isolated" means each person's camera and microphone should be recorded independently. It records locally and provides separate tracks, with support for up to 4K video and high-quality audio. Riverside Riverside

riverside.fm

So I'd choose:

• Streamer/gaming/content studio: OBS
• Professional multicamera/broadcast production: vMix
• Podcast/interview/remote guests: Riverside

If you tell me what you're streaming (gaming, podcast, live event, multicam studio, etc.), your cameras/mics, and Mac vs Windows, I can recommend the exact setup—including how I'd route the isolated tracks for Premiere/Resolve/FCP.

If you mean true ISO video recording

Then I'd look seriously at vMix.

Yes. If by “clean isolated” you mean you want to stream a finished program while simultaneously recording separate camera feeds and separate audio tracks for an editor, there are a few good options—but one stands out.

My pick: vMix

vMix is probably the best fit for a professional post-production workflow.

Its MultiCorder/ISO recording can record individual camera inputs simultaneously while you're producing and streaming the live program. That means your editor can later choose different camera angles, add graphics, re-cut scenes, etc., instead of being stuck with the program feed. vMix specifically describes its ISO recordings as clean camera feeds intended for post-production. vMix vMix

vmix.com

It also gives you independent audio inputs and professional mixing, including support for ASIO interfaces and multiple audio mixes. vMix vMix

The catch: vMix is Windows-only and the ISO workflow is in the 4K and Pro editions, with fairly substantial hardware/storage requirements. vMix vMix

How I'd rank the options

obsproject.com can record separate audio tracks, so it's surprisingly capable if you mainly need isolated audio rather than true multicamera ISO recording. OBS Studio

riverside.fm is particularly attractive if your production involves remote guests: its workflow is recording-first, with separate participant tracks, rather than relying on the compressed livestream as your master. SaaSCompared

streamyard.com is easier to operate than vMix and has local multitrack recording, but I'd choose it when simplicity and browser-based live production matter more than maximum control. StreamYard

If this is a serious production

I'd build it roughly like:

Cameras → capture/SDI/HDMI → vMix →

• Live program → YouTube/LinkedIn/etc.
• ISO Camera 1 → SSD
• ISO Camera 2 → SSD
• ISO Camera 3 → SSD
• Clean mic tracks → SSD
• Program/master recording → SSD

That gives you a broadcast feed and an edit-friendly set of source recordings.

If you tell me how many cameras, how many microphones/guests, Windows vs Mac, and where you're streaming (YouTube/Zoom/LinkedIn/etc.), I can recommend the exact software + hardware architecture.

It also gives you independent audio inputs and professional mixing, including support for ASIO interfaces and multiple audio mixes. vMix vMix

The catch: vMix is Windows-only and the ISO workflow is in the 4K and Pro editions, with fairly substantial hardware/storage requirements. vMix vMix

riverside.fm is particularly attractive if your production involves remote guests: its workflow is recording-first, with separate participant tracks, rather than relying on the compressed livestream as your master.

If your priority is clean isolated audio/video files for post-production while you are live streaming, you want ISO recording / multitrack recording, not just a normal stream recorder. The best choice depends on how “broadcast” your workflow is.

Best options

1. vmix.com — best for professional live production

Best for: studios, events, multi-camera shows, esports, broadcast-style streams.

Why it’s strong:

• Records individual camera sources separately (ISO recording) for editing later.
• Handles multiple cameras, capture cards, NDI sources, remote guests, graphics, and switching.
• Can stream and record at the same time. vMix

Tradeoffs:

• Windows only.
• Requires a more powerful production computer and more setup knowledge. Riverside

Pick this if: your stream is basically a live TV production and you have an operator or technical workflow.

2. riverside.fm — best for interviews, podcasts, webinars, creator content

Best for: remote guests, talking-head shows, podcasts, courses.

Why it’s strong:

• Records locally instead of relying only on the livestream feed.
• Captures separate audio/video tracks for participants.
• Designed for post-production workflows. Riverside Riverside

Tradeoffs:

• Less control than a full live production system.
• Not ideal for complex multi-camera shows with lots of live switching.

Pick this if: you want “everyone gets a clean camera + mic file automatically.”

3. obsproject.com — best free flexible option

Best for: creators who want control without paying.

Why it’s strong:

• Free and highly customizable.
• Can record while streaming.
• Supports multiple audio tracks and advanced routing with plugins. Riverside

Tradeoffs:

• ISO workflows require more setup.
• You may need tools like audio routing software, NDI, or extra recorders to get true “every source separately” workflows.

Pick this if: you’re willing to build your own setup.

4. ecamm.com — best Mac creator workflow

Best for: Mac-based streamers, interviews, YouTube/live content.

Why it’s strong:

• Very polished Mac workflow.
• Supports advanced streaming layouts and isolated audio features on higher tiers. Riverside

My recommendation by scenario

For a serious production pipeline, the ideal setup is usually:

• vMix/OBS/Ecamm → live switching + stream output
• ISO recording → isolated camera feeds
• Multitrack audio recorder or interface → isolated microphones
• DaVinci Resolve/Premiere → final edit

If you tell me your setup (number of cameras, remote guests or local, Mac/Windows, and where you stream—YouTube/Twitch/webinar/etc.), I can narrow it to a specific workflow.

Yes. If the requirement is “stream live, but simultaneously capture clean isolated source files for serious post-production,” I’d shortlist these:

My recommendation

If you're producing a show with multiple remote people: I'd lean StreamYard or Riverside. They record each participant locally, so the final files aren't dependent on the quality of the live stream. StreamYard, for example, can produce separate local audio/video files per participant and supports high-quality files for Premiere, Final Cut, and DaVinci Resolve. StreamYard StreamYard

If everyone/source feeds are on one production machine: OBS Studio is probably the better choice. You can route microphone, application audio, game/system audio, etc. to separate recording tracks rather than baking everything into the livestream mix. OBS Studio OBS Studio

The important distinction is isolated recording vs. simply recording the livestream. You want something like:

LIVE STREAM
 ├── Program video
 └── Program mix

POST-PRODUCTION MASTERS
 ├── Camera 1
 ├── Camera 2
 ├── Guest video
 ├── Host mic.wav
 ├── Guest mic.wav
 ├── System/app audio.wav
 └── Music/SFX.wav

That lets your editor completely remix the show afterward instead of trying to rescue the compressed livestream.

If you tell me your setup (number of cameras, number of people, remote vs. in-studio, platforms you're streaming to, and whether you edit in Premiere/Resolve/Final Cut), I can recommend the exact software + recording architecture.

If your requirement is “stream live, but simultaneously capture clean isolated audio/video sources for serious post-production,” I’d shortlist these:

My first choice: vMix

If you're on Windows, vMix is probably the strongest fit.

Its MultiCorder/ISO recording can record individual camera inputs independently while simultaneously producing and streaming the program feed. That means you can switch cameras live for the audience while retaining the clean camera feeds for editing later. vMix specifically describes ISO recordings as clean camera feeds intended for post-production. vMix vMix

It also handles multiple audio devices, ASIO interfaces, capture cards, NDI, SRT, remote guests, etc. vMix

This is the one I'd choose for a production-oriented workflow.

If you're on Mac: Ecamm Live

Ecamm Live has become particularly interesting for this exact use case.

Its Pro plan can record isolated video from up to three cameras plus individual audio tracks while simultaneously recording/streaming the program. It can also isolate guest audio/video. Ecamm Help Center

The big caveat: its ISO video is currently capped at 1080p, even when the source is 4K. Ecamm Help Center

OBS: great if you want flexibility

OBS Studio is still an excellent option, particularly because it's free and runs on Windows, Mac, and Linux. OBS Studio

OBS natively supports multiple audio recording tracks, so you can put your mic, guest, music, system audio, etc. on separate tracks for your editor. OBS Studio

For isolated video sources, though, you're more likely to be building a workflow around plugins/configuration rather than getting a polished ISO-production system out of the box. The Source Record plugin, for example, can independently record an OBS source. OBS Studio

Riverside: easiest for remote productions

Riverside is worth considering if you're doing podcasts, interviews, webinars, or remote guests rather than a complex studio.

It records locally with separate audio/video tracks and supports up to 4K video, which makes it attractive when the priority is getting high-quality post-production files without building a complicated production system. Riverside

What I'd pick

• Multi-camera studio / broadcast / serious production: vMix
• Mac studio / creator / interviews: Ecamm Live
• Remote podcast/interview: Riverside
• Free/custom/open-source: OBS Studio
• Maximum post-production flexibility: vMix + dedicated audio interface + ISO recording

One important distinction: don't confuse “multitrack” with “ISO.” Separate audio tracks are relatively easy. What you really want for post is clean ISO video feeds + isolated audio stems + a synchronized program recording.

If you tell me Mac or Windows, number of cameras, number of people/mics, resolution (1080/4K), and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact workflow and hardware/software combination.

It also handles multiple audio devices, ASIO interfaces, capture cards, NDI, SRT, remote guests, etc. vMix

This is the one I'd choose for a production-oriented workflow.

If you're on Mac: Ecamm Live

Ecamm Live has become particularly interesting for this exact use case.

Its Pro plan can record isolated video from up to three cameras plus individual audio tracks while simultaneously recording/streaming the program. It can also isolate guest audio/video. Ecamm Help Center

The big caveat: its ISO video is currently capped at 1080p, even when the source is 4K. Ecamm Help Center

OBS: great if you want flexibility

OBS Studio is still an excellent option, particularly because it's free and runs on Windows, Mac, and Linux. OBS Studio

OBS natively supports multiple audio recording tracks, so you can put your mic, guest, music, system audio, etc. on separate tracks for your editor. OBS Studio

For isolated video sources, though, you're more likely to be building a workflow around plugins/configuration rather than getting a polished ISO-production system out of the box. The Source Record plugin, for example, can independently record an OBS source. OBS Studio

Riverside: easiest for remote productions

Riverside is worth considering if you're doing podcasts, interviews, webinars, or remote guests rather than a complex studio.

It records locally with separate audio/video tracks and supports up to 4K video, which makes it attractive when the priority is getting high-quality post-production files without building a complicated production system.

What I'd pick

If your priority is streaming live while simultaneously capturing clean, isolated sources for serious post-production, I’d rank the options:

1. vmix.com — best for professional multi-camera production

• Its MultiCorder/ISO recording can record individual camera inputs independently while you stream the program feed. That means you can re-edit camera angles later rather than being stuck with the switched live output. vMix vMix
• It also supports multiple independent audio mixes and multichannel ASIO audio. vMix
• Best choice if: you're doing podcasts, interviews, events, multi-camera shows, or broadcast-style production.
• Catch: Windows only, and ISO recording is in the higher-tier editions.
• obsproject.com — best value / flexible option

• Free and open source.
• You can stream and record simultaneously, and configure multiple audio tracks for post. OBS also supports separate application-audio sources on Windows. OBS Studio OBS Studio
• Best choice if: you're primarily one/two cameras, screen capture, gaming, YouTube, or a relatively simple production.
• Limitation: it isn't as turnkey for true multi-camera ISO video recording as vMix.
• streamlabs.com — easiest creator-oriented option

• Supports up to six separate audio tracks, so mic, game, Discord, music, etc. can remain independently editable. Streamlabs Streamlabs
• Its Selective Recording can also let you control what goes to the stream versus the recording. Streamlabs
• Best choice if: you're a streamer/creator and audio isolation is more important than true camera ISO.

One important distinction

If by "clean isolated audio/video" you mean something like:

Live stream = edited program feed
Recording = Camera 1 clean + Camera 2 clean + Camera 3 clean + Mic 1 isolated + Mic 2 isolated + system audio isolated

then vMix is the strongest fit. That's specifically what ISO recording is designed for. vMix

If instead you mean:

One camera + several audio sources, with each audio source isolated for editing

I'd go OBS Studio unless you need more sophisticated production features.

If you tell me how many cameras, how many people/mics, whether you're on Mac or Windows, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup—including recording format, audio routing, and hardware.

If your priority is streaming live while capturing clean isolated audio/video files for editing later, you’re looking for ISO recording / multitrack recording, not just a normal stream recorder. The best choice depends on your production level:

Best overall for post-production workflows: riverside.fm

Best for: interviews, podcasts, remote guests, webinars, creator teams.

Why it’s strong:

• Records local, isolated tracks rather than relying only on the streamed feed.
• Captures separate participant audio/video tracks for editing.
• Good export workflow for Premiere, Final Cut, DaVinci, etc.
• Easier for guests because they can join from a browser. Riverside Riverside

Tradeoff:

• It is less of a full live TV control room; you get fewer advanced switching/graphics options than broadcast tools.

Best professional live-production option: vmix.com

Best for: broadcast-style streams, events, multi-camera shoots, studios.

Why it’s strong:

• Designed for simultaneously producing, streaming, and recording.
• Its MultiCorder feature can record isolated camera inputs (ISO feeds) for post-production. vMix vMix
• Works well with capture cards, NDI, multiple cameras, graphics, replay, and live switching.

Tradeoff:

• Windows only.
• Requires a powerful PC and more operator skill.

Best free/flexible option: obsproject.com

Best for: creators who want control without licensing costs.

Strengths:

• Free and open source.
• Excellent streaming engine.
• Supports multiple sources, audio routing, plugins, and custom recording setups. OBS Studio

Tradeoff:

• Out of the box, it is not as polished for true ISO workflows. You often need plugins, virtual audio routing, or additional tools to get a broadcast-style post workflow.

Best for a studio/podcast with remote guests

A typical high-quality setup:

• Riverside → remote guests + isolated recordings
• OBS/vMix → live switching, overlays, stream output
• DaVinci Resolve / Premiere Pro / Final Cut Pro → post-production

Quick recommendation by use case

If you mean a live stream where you have multiple cameras + separate mic tracks + want an editor to rebuild the show afterward, I would lean vMix (broadcast) or Riverside (creator/remote) depending on whether the cameras are in one studio or spread across locations.

Yes. If by “clean isolated” you mean record the camera(s), microphone(s), guests, gameplay/screen, etc. separately while simultaneously sending a live mixed stream, there are a few strong options.

My picks

• vMix — best for serious multi-camera production.

This is the one I'd choose if post-production flexibility is a priority. Its MultiCorder/ISO recording can record individual camera inputs as clean feeds while you simultaneously stream the program output. That means you can completely re-edit the show afterward rather than being stuck with the live switched feed. ISO recording is available in the 4K/PRO tiers. vMix vMix

• OBS Studio — best value / flexible DIY setup.

OBS can record multiple independent audio tracks while streaming—for example, mic, desktop/game audio, music, and other sources separately. OBS Studio
The catch is that OBS's native recording workflow isn't as turnkey for isolated camera ISO video as vMix. You can build sophisticated setups with plugins/NDI/etc., but it's more engineering.

• Streamlabs Desktop — easiest creator-oriented option.

It supports up to six separate audio tracks, and you can choose different audio routing for the stream versus the recording. Streamlabs Streamlabs Good if your main requirement is clean isolated audio rather than full broadcast-style camera ISO recording.

• Streamlabs Talk Studio — particularly interesting for remote interviews/podcasts.

Its local recording can capture separate raw audio and video tracks per participant, rather than giving you only the composited stream. Streamlabs Streamlabs

If this is for a professional production

I'd rank them:

vMix > OBS > Streamlabs Desktop > Talk Studio

If you have multiple cameras + multiple mics + remote guests and want to stream live while giving an editor pristine individual sources afterward, vMix is the closest match to what you're describing. It can simultaneously produce the live program and ISO-record the camera inputs. vMix vMix

If you tell me your setup—e.g. 2–4 cameras, number of microphones, remote guests, Mac/Windows, and whether you're streaming to YouTube/Twitch/etc.—I can recommend the exact workflow and hardware/software combination.

If by “clean isolated audio/video” you mean ISO recordings—each camera/person/audio source saved separately while you simultaneously send a live program feed—then vMix is probably the strongest fit.

My shortlist

• 🥇 vMix — best for professional live production + post

• Can stream and record simultaneously.
• Its MultiCorder records individual camera inputs as separate files, rather than just recording the switched program. vMix vMix
• Supports multiple independent audio mixes and multichannel audio inputs. vMix
• Excellent if you're doing multi-camera shows, podcasts, events, interviews, corporate production, or broadcast-style streams.
• Downside: Windows only, and the ISO functionality is in the higher-tier 4K/Pro editions. vMix
• 🥈 OBS Studio — best free/flexible option

• Free and open source.
• Can stream while recording locally.
• Supports up to 6 separate audio tracks, so you can keep mic, guests, Discord/comms, game/system audio, etc. separate for editing. OBS Studio OBS Studio
• Video ISO recording is less turnkey than vMix; you generally need additional sources/plugins/workarounds depending on exactly what you want isolated.
• Runs on Windows, macOS, and Linux. OBS Studio
• 🥉 Riverside — best for remote people/interviews

• Records participants locally rather than relying entirely on the livestream connection.
• Provides separate audio/video tracks and up to 4K recording, making it particularly attractive for podcasts and remote productions. Riverside Riverside
• Much easier than building a broadcast setup yourself.
• Less appropriate if you're doing a complex live-switching / multi-camera control-room production.

What I'd choose

If your workflow looks like:

Cameras + microphones → live switch/mix → YouTube/Twitch/etc.
while simultaneously getting:

Camera 1 ISO + Camera 2 ISO + Camera 3 ISO + isolated audio tracks → Premiere/Resolve

I'd go vMix.

If it's:

Host + remote guests → livestream → polished podcast/video afterward

I'd go Riverside.

If it's:

One/few cameras + screen/game capture → livestream → maximum flexibility for minimal cost

I'd go OBS Studio.

The important distinction is that “recording the stream” isn't the same as “ISO recording.” For serious post-production, you want the latter: clean camera feeds before graphics, transitions, and other live-program elements are baked in. vMix explicitly supports that workflow. vMix

If you tell me how many cameras, how many people/mics, Mac or Windows, and whether you're streaming to YouTube/Twitch/etc., I can recommend the exact setup/software stack.

Yes. If by “clean isolated” you mean record each camera/mic/source separately while simultaneously producing and streaming a live program, I’d narrow it to these:

Best overall: vMix

vmix.com is probably the strongest fit if you're on Windows and this is a professional post-production workflow.

• ISO records individual camera inputs rather than only the switched program feed.
• Its MultiCorder can record multiple camera inputs simultaneously.
• You can stream the edited/live program at the same time as recording the clean sources.
• Supports cameras, capture cards, NDI, SRT, audio interfaces, remote guests, graphics, etc.
• ISO recording is available in vMix 4K and PRO. vMix vMix
• Current vMix 29 also supports recording to separate drives for individual camera recordings, which is useful for demanding productions. vMix

If your priority is: “Give my editor clean camera files + clean audio while I simultaneously run the live show” → vMix is my first choice.

Best free option: OBS Studio

obsproject.com is excellent if budget matters.

It can:

• Stream and record simultaneously.
• Put different audio sources onto separate tracks.
• Capture individual application audio sources.
• Use different recording and streaming encoders/settings. OBS Studio OBS Studio OBS Studio

The limitation is that OBS isn't as naturally designed around true multi-camera ISO video recording as vMix. You can build sophisticated workflows around it, but it takes more configuration.

If you're primarily doing remote interviews/podcasts: Riverside

riverside.fm is worth considering if your “isolated” requirement is mostly each remote participant getting their own clean camera and microphone recording. That's a different problem from a multi-camera live-production ISO workflow. Current comparisons describe Riverside as recording participants locally and producing separate tracks/files for editing. SaaSCompared

My recommendation

One important distinction: if you mean clean isolated video feeds—camera 1, camera 2, screen capture, etc.—vMix is substantially closer to what you're describing than typical streaming platforms. Its ISO recording is specifically designed to preserve clean camera feeds for post-production. vMix

If you tell me how many cameras, how many separate microphones, resolution/frame rate (1080p/4K), Mac vs Windows, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact software + recording architecture.

Yes — what you’re describing is usually called ISO (isolated) recording: you stream a live program while simultaneously saving clean, separate camera and audio sources for editing afterward.

My top picks

1. ecamm.com — best if you're on Mac

• Records each camera separately rather than baking everything into the live program.
• Records individual microphones, guests, sound effects, app audio, etc. as separate audio files.
• Can choose whether camera effects are included, giving you a cleaner source for post.
• Particularly nice for podcasts, interviews, multicam shows, and creator-style productions.
• Catch: ISO video requires the Pro plan and Apple Silicon; ISO video is capped at 1080p according to Ecamm's current documentation. Ecamm Help Center Ecamm Help Center
• vmix.com — best for serious/production environments

• vMix's MultiCorder can ISO-record camera inputs while you're streaming.
• Designed more like a professional live-production system: lots of cameras, capture cards, NDI, SDI, remote guests, etc.
• ISO recording is available in vMix 4K and PRO. vMix vMix
• I'd pick this if you're building a proper studio or broadcast workflow rather than a creator setup.
• obsproject.com — best free/flexible option

• Free, open source, Windows/Mac/Linux.
• Excellent streaming and recording engine, but getting a polished fully isolated post-production workflow generally takes more configuration than Ecamm or vMix. OBS Studio

What I'd choose

If your workflow is something like:

2–3 cameras + multiple mics → live stream → simultaneously capture clean sources → edit in Premiere/Resolve/FCP afterward

I'd go Ecamm Pro on an Apple Silicon Mac for simplicity, or vMix 4K/Pro on Windows if you're doing a more elaborate production.

The important distinction is that you don't want merely "record while streaming." You want ISO recording + clean feeds, so that afterward you have something like:

Camera 1 — clean video
Camera 2 — clean video
Camera 3 — clean video
Mic 1 — isolated audio
Mic 2 — isolated audio
Guest — isolated audio/video
Program — finished live mix

That gives your editor vastly more flexibility.

If you tell me Mac or Windows, number of cameras/mics, and whether you're streaming to YouTube/Twitch/etc., I can narrow it down to the best setup and tell you exactly what I'd use.

Yes. If by “clean isolated” you mean each camera/mic recorded independently while the program is simultaneously being streamed, I’d narrow it to these:

Best overall: vMix

vmix.com

For a serious production workflow, vMix is probably the strongest fit. Its MultiCorder feature can ISO-record individual camera inputs while you simultaneously produce and stream the live program. The ISO files are clean feeds, so you can completely re-edit the show afterward. ISO recording is available in vMix 4K and Pro. vMix vMix

It also handles:

• Multiple cameras/capture cards
• Separate audio sources
• NDI/SRT
• Remote guests
• Graphics/titles
• Simultaneous recording + streaming
• Professional output formats

Catch: Windows only, and you'll want a fairly powerful machine and fast SSDs for multiple simultaneous recordings. vMix

Best free option: OBS Studio

obsproject.com

OBS is excellent if you want maximum flexibility without paying for the software. It can record multiple isolated audio tracks, which is very useful for post. OBS Studio

However, OBS isn't as turnkey for ISO video recording of multiple cameras as vMix. You can build sophisticated setups with plugins, scenes, multiple OBS instances, etc., but it takes more engineering.

Best for remote interviews/podcasts: Riverside

riverside.fm

If your production involves remote people, Riverside is particularly attractive. It records participants locally and gives you separate high-quality tracks rather than relying solely on the compressed livestream feed. It supports up to 4K recording and separate audio/video tracks. Riverside Riverside

It's less of a traditional broadcast-control-room tool than vMix, though.

My recommendation

If you're doing something like a studio show with 3–6 cameras, multiple microphones, graphics, and a livestream, I'd go vMix + local ISO recording. You get the live program and clean camera masters for the editor afterward.

If you tell me how many cameras, microphones, whether you're on Mac or Windows, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact software + recording setup.

Yes — if by “clean isolated” you mean record each camera and each microphone/source separately while simultaneously producing and streaming the live program, there are a few strong options.

My top picks

• ecamm.com — best for Mac / podcasts / creator productions.

Its Pro tier can record isolated video from up to three cameras plus separate audio files for microphones, guests, sound effects, app audio, etc. Ecamm Help Center Ecamm Help Center
A particularly useful feature for post is that you can choose whether camera effects are baked into the ISO recording or record the source clean. Ecamm Help Center
Caveat: ISO video is capped at 1080p and requires an Apple-silicon Mac. Ecamm Help Center

• vmix.com — best for serious multi-camera production / Windows.

vMix's MultiCorder can ISO-record camera inputs independently while you're producing and streaming. The ISO feature is available in the 4K and Pro editions. vMix vMix
This is the one I'd look at if you're doing 4K, lots of cameras, SDI/NDI, dedicated production hardware, or broadcast-style workflows.

• OBS Studio — excellent free option, particularly if you build the recording architecture yourself. It's very flexible, but for your specific requirement—clean ISO video + isolated audio automatically generated during a live production—I'd generally favor Ecamm or vMix because that's much more native to their workflow.

What I'd choose

If “clean” is the critical word, I'd lean toward vMix for a Windows/broadcast setup and Ecamm for a Mac/creator setup. Ecamm explicitly lets you keep the ISO camera footage free of its camera effects, while vMix's ISO workflow is designed around giving you clean individual camera feeds for post-production. Ecamm Help Center vMix

If you tell me Mac or Windows, number of cameras, resolution (1080/4K), streaming platform, and whether you need separate mic tracks, I can narrow it down to the best exact workflow.

Yes. If the requirement is “stream live, but simultaneously capture clean isolated sources for serious post-production,” I’d shortlist these:

My pick depends on your setup

If you have multiple physical cameras and want a TV-style production:
Go with vmix.com. Its MultiCorder can ISO-record individual camera inputs while simultaneously producing and streaming the live program. Those clean camera feeds are specifically intended for post-production. vMix vMix

If you're recording remote people:
riverside.fm is probably the easiest. Each participant's audio/video is recorded locally rather than simply capturing the compressed livestream, and you can download individual tracks afterward. It supports up to 4K video and uncompressed WAV audio. Riverside Riverside Help Center

If you're on Mac and doing podcasts/interviews/live shows:
ecamm.com is particularly compelling. Its isolated audio feature records individual guests, microphones and sound effects separately, while ISO video gives you individual camera sources rather than just the final program feed. Ecamm YouTube

If you want free/open-source and don't mind configuring it:
obsproject.com can record multiple separate audio tracks, which works very well for post. OBS Studio

For your exact wording

If “clean isolated audio/video” is the priority, I'd rank them:

vMix > Ecamm > Riverside > OBS

But that's assuming you're talking about a studio/live production with local cameras and microphones. If you're talking about Zoom-style remote guests, I'd flip that to:

Riverside > vMix > Ecamm > OBS

If you tell me Mac or Windows, number of cameras, number of people, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup—including which one will give you ISO camera files + separate WAVs + clean program feed simultaneously.

Yes — if the key requirement is “stream live, but simultaneously capture clean isolated sources for a real post-production edit,” I’d put vMix at the top of the list.

Best fit: vmix.com

vMix is specifically built around this workflow:

• Live stream + record simultaneously from the same production system. vMix
• ISO record individual camera inputs rather than just recording the switched program. Its MultiCorder can record multiple camera inputs simultaneously, giving you clean camera feeds for editing later. vMix vMix
• Supports high-quality recording formats, including 4K, and can record raw inputs without putting your live graphics/transitions into the source footage. vMix vMix
• For audio, it has a proper mixer, multiple independent audio buses, ASIO/multichannel input support, and VST3 processing. vMix vMix
• You can therefore build a workflow like Camera 1 ISO + Camera 2 ISO + Camera 3 ISO + isolated mics + clean program + streamed program.

The big caveat: vMix is Windows-only. vMix

If you want something cheaper/flexible: OBS

obsproject.com is excellent for streaming and can record multiple isolated audio tracks for post-production. OBS Studio

But there's an important distinction:

OBS is much better at isolated audio than true camera ISO recording. If you have three cameras and want three clean, independently editable video files while simultaneously producing the live switched stream, I'd favor vMix.

My ranking

Streamlabs can also separate audio tracks for recording, but it requires more routing/setup to achieve a clean split between stream and recording. Streamlabs

So if you're doing a serious multi-camera production — podcast, interview, live show, music, event, etc. — I'd choose vMix 4K/Pro rather than OBS. The fact that vMix's MultiCorder is explicitly designed to ISO-record cameras for post is the deciding feature. vMix

If you tell me how many cameras, how many microphones, Mac or Windows, and what you're streaming to (YouTube/Twitch/etc.), I can recommend the exact software + hardware workflow.

If your priority is clean ISO audio/video for post while simultaneously streaming, I’d put vMix at the top of the list—especially for a professional multi-camera production.

Best options

• vmix.com — Best overall for serious production

• Can stream and record simultaneously.
• MultiCorder can ISO-record individual camera inputs rather than just the program feed.
• You can keep clean camera feeds without your live graphics/lower thirds baked in, which is exactly what you want for post. vMix vMix
• Has a proper audio mixer with EQ, compression, noise gates, multiple buses, ASIO interfaces, etc. vMix vMix
• Supports NDI, SDI/capture cards, remote guests, multiple outputs, and professional codecs/workflows.
• Downside: Windows only. vMix
• obsproject.com — Best free option

• Excellent for streaming and can record multiple isolated audio tracks—mic, desktop, music, guests, etc. OBS Studio
• Much less expensive and very flexible.
• The important distinction is that OBS's native strength is separate audio tracks, whereas vMix is much stronger when you need actual isolated camera recordings/ISOs.
• Great choice if you're doing one/two cameras and don't need a broadcast-style production system.
• streamlabs.com — Good creator-oriented alternative

• Supports up to six separate audio tracks, so you can independently edit mic, desktop audio, etc. afterward. Streamlabs Streamlabs
• Easier for a typical streamer than vMix, but I wouldn't choose it over vMix for a serious multi-camera/post-production workflow.

What I'd choose

If you're describing something like:

Camera 1 + Camera 2 + Camera 3 + isolated mics → live switch/graphics → stream, while simultaneously saving:

CAM1_clean.mov
CAM2_clean.mov
CAM3_clean.mov
Mic_1.wav/track
Mic_2.wav/track
Program_with_graphics

then vMix is the closest fit. Its MultiCorder is specifically designed to record individual camera inputs for post-production while you're producing the live show. vMix

If you're doing one or two cameras and mostly need isolated audio, I'd save the money and use OBS.

If you tell me how many cameras, microphones, whether you're on Mac or Windows, and what you're streaming to (YouTube/Twitch/etc.), I can narrow it down to the best exact setup—including hardware and recording formats.

If your priority is streaming live while capturing clean isolated audio/video files for later editing, you want software with ISO recording / local recording / multitrack capture, not just a screen recorder.

The best choices depend on your production style:

My shortlist:

• Remote interviews / podcasts: Riverside
• Live show + polished edits afterward: StreamYard or Riverside
• You have cameras, switchers, capture cards, and an operator: vMix
• You want maximum control and lowest cost: OBS
• Mac-only creator workflow: Ecamm Live

A common pro workflow is:

• Stream output → YouTube/Twitch/LinkedIn/etc.
• ISO recordings → editor receives separate camera and mic files
• Edit in Adobe Premiere Pro, Final Cut Pro, or DaVinci Resolve

If you tell me:

1. number of cameras,
2. number of remote guests,
3. Mac or Windows,
4. where you stream (YouTube, Twitch, corporate webinar, etc.),

I can narrow it to the best setup.

Yes — if your priority is clean isolated audio/video for post-production while simultaneously streaming, I’d shortlist these:

🥇 My pick: vMix

If you're doing a real production—multiple cameras, graphics, guests, switching, etc.—I'd go with vMix. It can stream and record simultaneously, and its ISO recording can capture individual camera sources for post-production. vMix specifically says ISO recording is available in its 4K and PRO editions. doc.vmix.com

The big advantage is that you can have:

Live program feed → stream
Camera 1 → clean ISO
Camera 2 → clean ISO
Camera 3 → clean ISO
Individual audio sources → independent mixes/tracks

That's much closer to a broadcast/post-production workflow.

vMix official site

🥈 Riverside if you're recording people remotely

For podcasts, interviews, webinars, or remote productions, Riverside is arguably easier. It records each participant locally, producing separate high-quality audio/video tracks rather than relying on the streamed/compressed feed. It supports up to 4K video and WAV audio tracks. support.riverside.com

That's particularly valuable if your concern is "I don't want my post-production master to be the same compressed thing viewers saw on the stream."

Riverside official site

🥉 OBS if budget/flexibility matters

OBS Studio is fantastic for streaming and can record multiple separate audio tracks. You can assign microphones and other sources to individual tracks for editing later. obsproject.com

But I'd choose it more for streaming-first setups than for a serious multi-camera ISO production workflow.

OBS Studio official site

So, in one sentence:

• Broadcast / multi-camera / serious post: vMix
• Remote people / podcast / interview: Riverside
• Free + highly customizable: OBS

If you tell me how many cameras/mics you have, whether guests are remote, and whether you're on Mac or Windows, I can recommend the exact setup and recording workflow.

Yes. If by “clean isolated” you mean record each camera and audio source separately while simultaneously sending a live program feed, there are two standouts:

🥇 vMix — best for serious post-production

vMix is probably the closest match to what you're describing.

• ISO-records individual camera inputs rather than just recording the switched program. www.vmix.comwww.vmix.com
• Can stream and record simultaneously. www.vmix.comwww.vmix.com
• Has extensive audio routing: independent buses and multichannel recording options. www.vmix.com
• Handles cameras, capture cards, NDI, SRT, remote guests, graphics, etc.
• Excellent if you're essentially building a small live-production/post-production system.
• Windows only. www.vmix.com
• ISO recording requires vMix 4K or PRO. www.vmix.comwww.vmix.comwww.vmix.com

vMix official site

🥈 OBS Studio — best value/flexibility

OBS Studio is fantastic if you don't necessarily need true video ISO recording.

It can simultaneously stream and record, and you can put different audio sources onto separate recording tracks—for example:

• Track 1: complete stream mix
• Track 2: microphone
• Track 3: Discord/remote guests
• Track 4: game/system audio
• Track 5: music
• Track 6: other production audio

OBS supports up to six audio tracks, with independent source assignment. obsproject.comwww.vmix.com

OBS Studio official site

The important distinction is that OBS's built-in recording is primarily a mixed video recording, whereas vMix's MultiCorder is specifically designed to record individual camera inputs as ISOs. obsproject.comwww.vmix.com

🥉 Riverside — easiest if you're doing interviews/remote production

Riverside is worth considering if this is more of a podcast/interview/webinar workflow than a multi-camera broadcast.

It records locally with separate audio tracks and up to 4K video, making the files much more useful for post-production. riverside.com

Riverside official site

My recommendation

If you tell me how many cameras, how many audio sources, Mac vs. Windows, resolution (1080p/4K), and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup—including how I'd route the isolated audio/video so your editor gets clean post-production files.

If your priority is clean isolated audio/video for post-production while simultaneously streaming, I’d narrow it to three:

My pick: vMix

If you're talking about a real production workflow—multiple cameras, mics, graphics, switching live, and then wanting pristine footage afterward—vMix is probably the strongest fit.

Its MultiCorder can ISO-record individual camera inputs while simultaneously recording the program output and streaming. The ISO feeds are clean camera sources, which means you can completely change the edit afterward rather than being stuck with whatever you switched live. www.vmix.com

vMix official site

If you're doing remote interviews: Riverside

For something like podcasts, interviews, webinars, or a show with remote guests, I'd actually choose Riverside. It records each participant locally on their own machine, producing separate high-quality video and WAV audio tracks. Internet problems don't degrade those local tracks. support.riverside.com

It can also stream live, including 1080p streaming while recording up to 4K, with separate audio/video/screen-share tracks. marketing.riverside.com

Riverside official site

OBS

OBS is fantastic if you want free + extremely flexible, but I'd put it behind vMix for a serious ISO post-production workflow. It is primarily a live production/recording mixer; getting a sophisticated isolated-recording setup usually means configuring multiple audio tracks, sources, plugins, or additional recording tools. obsproject.com

OBS Studio official site

So, in one sentence:
vMix for a studio/multi-camera production, Riverside for remote people, OBS if budget/flexibility is the priority.

If you tell me how many cameras + microphones, whether guests are remote, and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup and recording architecture so you get clean ISO files + a finished live program simultaneously.

If your priority is clean, isolated source recordings while simultaneously producing a live stream, I’d narrow it to OBS Studio vs. vMix.

My pick: vMix — if you're doing serious multi-camera production

vMix is particularly strong for this workflow because its MultiCorder can record individual camera inputs as clean ISO files while you simultaneously stream the program output. That means your editor can re-cut the production later using the original camera feeds rather than being stuck with the live switched program. www.vmix.comsupport.streamlabs.com

It also has sophisticated audio routing: multiple independent audio buses can be configured, so you can keep microphones, cameras, playback, etc. independently controllable rather than baking everything into the stream mix. www.vmix.com

Best for:

• Multiple physical cameras
• Live switching + streaming
• Clean camera ISOs for post
• Separate audio mixes
• Professional productions
• Windows production machines

The catch is that ISO recording requires vMix 4K or PRO, and it can be demanding on the production PC. www.vmix.com

Best value/flexibility: OBS Studio

OBS Studio is excellent if you primarily need isolated audio rather than full camera ISO recording.

OBS can stream while recording and put individual audio sources onto separate tracks—for example:

• Track 1 → complete stream mix
• Track 2 → microphone
• Track 3 → game/desktop
• Track 4 → guest/Discord
• Track 5 → music

That gives your editor independent control of the sources afterward. OBS officially documents recording up to six audio tracks. obsproject.com

For video, though, OBS isn't as naturally oriented around recording every camera as an isolated clean feed. You can build sophisticated workflows, but vMix is considerably more purpose-built for that.

Streamlabs

Streamlabs can also record up to six separate audio tracks and has a particularly useful Selective Recording feature that lets the recorded video contain different sources from the live stream. support.streamlabs.com

I'd choose it primarily for a creator/gaming workflow rather than a professional multi-camera post-production workflow.

Bottom line

If by “isolated audio/video” you mean something like “we want to stream a podcast/interview but simultaneously save clean 4K camera files + isolated lav/boom audio + the live program mix”, then vMix is the one I'd investigate first. Its ISO workflow is specifically designed for exactly that. www.vmix.com

vMix official site
OBS Studio official site

Yes. If the requirement is “stream live while simultaneously capturing clean, isolated sources for a serious post-production workflow,” I’d narrow it to these:

Best overall: OBS Studio

OBS Studio

Best if you want maximum control and don’t mind configuring the workflow. OBS can simultaneously stream and record, route different audio sources to separate tracks, and capture individual applications separately. Its official documentation specifically supports multi-track recording for post-production. obsproject.com

Typical setup:

• Stream output: finished program mix
• Recording: clean mic track + game/system track + guest/Discord track + music, etc.
• Video: program recording, with more advanced ISO workflows possible

The downside is that true isolated video recording is more complicated than isolated audio in standard OBS. For a multi-camera production, you'll need additional configuration/plugins or a more production-oriented application.

Best turnkey ISO workflow on Mac: Ecamm Live

Ecamm Live

This is particularly interesting if you're on an Apple Silicon Mac. Ecamm's current Pro plan can record isolated audio and video files for individual cameras/sources while simultaneously recording the program/live stream. Each selected camera gets its own movie file, and audio components can be captured separately. support.ecamm.com

That's much closer to what a traditional production team means by ISO recording.

One important limitation: Ecamm's ISO video recordings are currently capped at 1080p, even when the main program can be higher resolution. support.ecamm.com

Best if you want an easier OBS-like workflow: Streamlabs Desktop

Streamlabs Desktop

Streamlabs supports multi-track audio and, importantly, Selective Recording—you can have sources appear in the livestream but not in the recording, or vice versa. support.streamlabs.com

That's useful for things like:

• Stream alerts → live only
• Clean camera → recording
• Commentary mic → recording
• Music → live mix but excluded from the master recording

My recommendation

If you're producing professional video/podcast/interview content:

Mac + multiple cameras → Ecamm Live
Windows or maximum flexibility → OBS Studio
Easy creator-oriented workflow → Streamlabs Desktop

If by “isolated audio/video” you mean each camera gets its own clean video file and each microphone gets its own unprocessed WAV/track, while the audience receives a completely separate live mix, tell me Mac or Windows + how many cameras/mics, and I can recommend the exact production setup.

Yes — if clean isolated recordings for post-production are the priority, I’d shortlist these:

Best overall: vMix

vMix

If you’re on Windows, vMix is probably the strongest fit for a serious production workflow. Its MultiCorder can record the raw video/audio from individual camera and NDI inputs to separate files while simultaneously recording and streaming the finished program. That means your editor can get the clean camera feeds rather than having to extract them from the live program. www.vmix.com

It also has multiple independent audio buses, so you can keep your streaming mix separate from what you're recording. www.vmix.com

I'd pick vMix if: multi-camera, professional post, Windows workstation, lots of sources, or you eventually want SDI/NDI/SRT.

Best/easiest on Mac: Ecamm Live

Ecamm Live

Ecamm is particularly good if you're on an Apple Silicon Mac and want a much simpler interface. Its Pro plan can record individual camera feeds and individual audio tracks simultaneously with the stream. You can get separate files for cameras and clean recordings of microphones, guests, sound effects, etc. support.ecamm.com

One important limitation: Ecamm's ISO video recordings are currently capped at 1080p, even if the source/main recording is 4K. support.ecamm.com

Best free option: OBS Studio

OBS Studio

OBS is excellent if you don't necessarily need true ISO video. It can record multiple separate audio tracks, which is very useful for post-production, but its workflow is less turnkey for recording individual clean camera feeds than vMix's MultiCorder or Ecamm's ISO system. obsproject.com

My ranking

If you tell me your setup — Mac or Windows, number of cameras, resolution (1080/4K), audio sources, and where you're streaming (YouTube/Twitch/etc.) — I can tell you exactly which one I'd use and how I'd configure the recording/stream split.

If the goal is live streaming while simultaneously capturing clean, isolated sources for serious post-production, I’d shortlist these:

🥇 Best overall: vMix

vMix

For a professional multi-camera production, vMix is probably the strongest fit. Its ISO recording can capture individual camera inputs separately while also recording/streaming the finished program. That means you can stream a switched show live but later rebuild the edit from clean camera feeds. doc.vmix.com

Best for: multi-camera studios, live shows, events, podcasts with multiple cameras, broadcast-style productions.

🥈 Best for remote guests: Riverside

Riverside

If your production involves remote people, Riverside is exceptionally good. It records locally on each participant's device, giving you separate high-quality video and audio tracks rather than relying on the livestream's compressed feed. It can also livestream while recording. riverside.fm

You can download individual MP4 video and WAV audio tracks for editing in Premiere, Resolve, Final Cut, etc. support.riverside.com

Best for: podcasts, interviews, remote contributors, webinars, distributed production teams.

🥉 Best inexpensive/flexible option: OBS Studio

OBS Studio

OBS is fantastic if you're primarily streaming and want to build your own workflow. It supports multiple isolated audio tracks, so you can keep microphones, desktop audio, music, etc. separated for post. obsproject.com

The limitation is that OBS isn't as turnkey for ISO video recording of multiple cameras as vMix.

Also worth considering: Ecamm Live

Ecamm Live

If you're on an Apple Silicon Mac, Ecamm has added genuine isolated audio/video recording: individual camera movie files plus clean individual audio tracks alongside your program/stream recording. The catch is that ISO recording is currently Pro-only, Mac/Apple-Silicon-only, and capped at 1080p. support.ecamm.com

What I'd choose

If you tell me your exact setup (number of cameras, microphones, Mac/PC, streaming destinations, and whether you have remote guests), I can recommend the specific workflow—including how I'd route the audio so the stream gets a polished mix while the editor gets clean isolated WAVs + clean camera feeds.

If the priority is “stream live, but simultaneously capture clean isolated sources for a real post-production workflow,” I’d narrow it to these:

My pick: Ecamm if you're on Mac

Ecamm is unusually well suited to exactly what you're describing. Its Pro plan can record each camera as its own video file and each microphone/audio source as its own audio file, while simultaneously producing the live program. You can even choose whether camera ISO files contain the clean camera feed or your applied camera effects. support.ecamm.com

The important part is that the ISO recordings aren't simply the finished stream with graphics burned in. You're getting the individual sources so an editor can rebuild the production afterward. Ecamm also automatically records the broadcast locally. support.ecamm.com

Caveat: ISO video requires an Apple Silicon Mac and is capped at 1080p. support.ecamm.com

If you're doing a more serious broadcast: vMix

I'd choose vMix if you're on Windows and have multiple cameras, SDI/NDI sources, complex audio, replay, graphics, etc. Its MultiCorder can independently record camera inputs, specifically intended to give you clean camera material for post-production. ISO recording is available in the 4K and PRO editions. www.vmix.com

vMix also has considerably deeper audio routing: independent buses and multiple controllable outputs make it much better suited to a proper production audio workflow. www.vmix.com

OBS is great, but I'd put it third for this particular requirement

OBS can absolutely be configured for multitrack recording, and it's excellent if you want something free and highly customizable. But if your goal is “hit Stream and automatically get a clean, editor-friendly set of isolated camera + audio files,” Ecamm or vMix is a more purpose-built solution.

So:

• Mac + podcast/interview/creator production → Ecamm
• Windows + multi-camera professional production → vMix
• Free/custom/technical setup → OBS

If you tell me Mac or Windows, number of cameras, number of microphones/guests, and whether you need 4K, I can recommend the exact setup—including what gets recorded locally versus what gets sent to the stream.

If your priority is clean ISO recordings for post-production while simultaneously streaming, I’d shortlist these:

🥇 Best overall for Mac: Ecamm Live

This is probably the closest match to what you described.

• Records each camera as its own video file
• Records each microphone/audio source separately
• Can record guests separately
• Streams and records simultaneously
• You can choose whether camera effects are baked into the ISO recording
• Pro can use a separate encoder for recording, so stream bitrate changes don't compromise your master recording. support.ecamm.comwww.vmix.comobsproject.comsupport.ecamm.com
• ISO video currently tops out at 1080p, even when the main program can be 4K. support.ecamm.com

If you're on an Apple Silicon Mac, I'd choose Ecamm for a podcast/interview/show workflow.

🥈 Best for serious multi-camera production: vMix

If you're on Windows and want something more broadcast-oriented, vMix is extremely capable.

Its MultiCorder can record the raw video/audio from individual inputs into separate files in addition to the main program recording. It supports cameras, NDI sources, and multiple simultaneous recordings. www.vmix.comsupport.ecamm.com

That's particularly attractive if you're doing multiple physical cameras + external audio + NDI + a clean program feed.

🥉 Best free/flexible option: OBS Studio

OBS is excellent for streaming and can separate audio sources/tracks—for example, keeping microphone, desktop/application audio, etc. independent in the recording. obsproject.com

But for your specific requirement, ISO video recording + clean post-production workflow, you'll generally need more configuration and potentially additional plugins/tools than with Ecamm or vMix.

My recommendation

One important distinction: if by “clean isolated” you mean camera feeds with no overlays, transitions, graphics, or compression from the livestream baked in, then vMix MultiCorder is particularly strong, while Ecamm's ISO recording is designed specifically around that post-production use case too. Ecamm can even record camera sources without applied camera effects. www.vmix.comsupport.ecamm.com

If you tell me Mac or Windows, number of cameras, resolution (1080/4K), and whether you're recording guests remotely, I can tell you exactly which setup I'd use.

Yes. If your goal is live streaming + simultaneously capturing clean, isolated source files for serious post-production, I’d narrow it to these:

My pick: Ecamm Live

If you're on an Apple Silicon Mac, Ecamm is particularly compelling. Its Pro plan can record individual camera sources and individual audio sources while you're streaming, rather than just saving the final program feed. You can get separate files for cameras, microphones, guests, sound effects, etc. support.ecamm.comwww.vmix.com

That means your workflow can look like:

Cameras → Ecamm → live stream
↳ Camera 1 ISO
↳ Camera 2 ISO
↳ Guest ISO
↳ Mic 1 WAV-ish audio track
↳ Mic 2 audio track
↳ Program/master recording

That's exactly the sort of setup I'd want if the stream is the live deliverable but the recordings are the source material for an editor.

One caveat: Ecamm's ISO video is currently capped at 1080p, and isolated recording requires an Apple Silicon Mac. It can also use a separate encoder for recording so stream bitrate limitations don't degrade the local recording. support.ecamm.com

If you're doing a serious multi-camera production: vMix

I'd choose vMix instead if this is more like a small broadcast studio—multiple cameras, capture cards, graphics, NDI, SDI, lots of sources, etc. Its MultiCorder can ISO-record camera inputs while simultaneously producing the live program, with ISO recording available in the 4K and PRO editions. www.vmix.com

If remote guests are the main thing: Riverside

Riverside is different: it's optimized around recording each participant locally on their own device, then giving you separate synchronized tracks. Its high-quality tracks can reach 4K video and are available as separate audio/video files for offline editing. support.riverside.com

So if you're doing something like host + 3 remote guests, I'd strongly consider Riverside over a traditional streaming switcher.

Bottom line:

• Mac + live show + local ISO files → Ecamm
• Professional multi-camera/broadcast setup → vMix
• Remote podcast/interviews → Riverside
• Free/open/customizable → OBS

If you tell me Mac or Windows, number of cameras/mics, resolution (1080p/4K), and where you're streaming (YouTube/Twitch/etc.), I can recommend the exact setup and recording architecture.

If your priority is clean isolated audio/video files for post-production while also live streaming, you want a tool that does ISO recording (isolated tracks), not just a stream recorder. The best choice depends on your production style:

My recommendations by scenario:

• Two or more cameras + serious editing later (Premiere/DaVinci/FCP):

→ vMix (Windows) is probably the strongest fit. You can stream the finished show while keeping clean camera masters. www.vmix.com

• Podcast/interview with remote guests:

→ Riverside is usually the easiest because guests don’t need a complex setup and you get isolated tracks. riverside.comriverside.com

• Solo creator with cameras, mic, overlays, and a small budget:

→ OBS Studio plus proper audio routing can get surprisingly close. riverside.com

• TV-style production:

→ vMix, Wirecast, or a hardware switcher + ISO recorders.

A high-quality workflow many creators use:

1. Cameras → capture cards/NDI → vMix or OBS
2. Microphones → audio interface → isolated tracks
3. Stream output → YouTube/Twitch/etc.
4. Record ISO camera feeds + multitrack audio locally
5. Edit from the clean files afterward

If you tell me your setup (number of cameras, Windows/Mac, remote guests or not, streaming platform, and editing software), I can narrow it down to the best workflow.
