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.

🥈 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.
