For long coding walkthroughs (1–8+ hours), avoiding file-size caps is mostly about recording locally rather than using cloud-first tools. My top picks:

sharerec.comwww.tella.com

My recommendation: OBS Studio

For coding walkthroughs, I’d use:

• Recording: OBS Studio
• Format: MKV while recording (safer if OBS crashes), then remux to MP4
• Encoder: hardware encoder if available (NVENC on NVIDIA, AMF on AMD, VideoToolbox on Mac)
• Resolution: 1080p
• FPS: 30 (plenty for IDE/tutorial content)
• Bitrate: ~6,000–10,000 kbps for clean code text

A 3-hour coding session might still be several GB, but you won't hit a software-imposed cap. sharerec.comwww.tella.com

File-size tricks that matter

For huge recordings:

1. Record MKV, not MP4
   • A crash won't corrupt the whole file.

2. Use H.265/HEVC if your editor supports it
   • Much smaller files than H.264, though compatibility is slightly worse.

3. Don't record 60 FPS
   • Coding tutorials rarely benefit from it.

4. Split intentionally
   • Record chapters (setup, coding, debugging, recap) rather than one 12-hour monster file. Easier to edit and upload.

If you want a “record → upload → share link” workflow

Consider:

• Loom — extremely convenient, but free tiers are generally not aimed at multi-hour courses. zapier.com
• ScreenPal — simpler than OBS, but free limits may matter depending on your workflow. sharerec.comwww.tella.com

Budget setup I’d pick

$0 setup:

• OBS Studio
• DaVinci Resolve for editing
• YouTube (unlisted) or your own storage for hosting

Under ~$20/month if you want convenience:

• OBS Studio for capture
• Cloud storage (Google Drive/Dropbox/etc.)
• Optional transcription tool afterward

For a developer making serious walkthroughs, OBS is the one I’d start with. It scales from a 20-minute bug fix recording to a full multi-day course.

If your priority is long coding walkthroughs without artificial recording/file-size limits, I’d go with OBS Studio.

My picks

1. OBS Studio — best budget choice

OBS Studio

It's free/open-source and runs on Windows, macOS, and Linux. It supports screen/window capture, webcam, multiple audio sources, scenes, etc. obsproject.com

For coding tutorials, I'd record locally, rather than uploading directly to a service. That means you're constrained primarily by your available disk space, not a SaaS file-size quota.

A good setup is:

• 1440p or 1080p
• 30 fps
• H.264 or HEVC hardware encoding if your GPU supports it
• MKV recording format, then automatically remux to MP4
• Separate microphone track if you want easier editing
• Record the IDE + terminal/browser as separate sources when useful

2. ScreenPal Deluxe — best if you want simplicity

ScreenPal pricing

This is probably the sweet spot if you don't want to spend time configuring OBS. Its current Deluxe plan is listed at $4/month when paid annually (the site is currently showing a promotional $3/month rate), and it gives you unlimited recording plus editing and hosting. screenpal.com

The free version is not suitable for your use case because it caps each recording at 15 minutes. obsproject.comsupport.screenpal.com

What I'd actually do

$0/month: OBS + local storage + YouTube for distribution.

~$4/month: ScreenPal Deluxe if you want recording + editing + hosting in one package.

The important distinction is that "unlimited recording" isn't necessarily "unlimited file size." A two-hour 1440p recording can easily be several GB. With OBS, that's fine as long as you have enough storage.

If you're recording a lot of coding content, I'd spend the money on storage rather than an expensive recorder subscription. For example, a 1TB external SSD gives you a lot of breathing room:

Kingston XS2000 1TB

$89.00

Seagate One Touch SSD 1TB

$99.00

SanDisk Extreme 1TB

$119.00

My recommendation: OBS + a 1TB/2TB SSD. It's the lowest-cost setup with essentially no artificial recording limits, and it's particularly well suited to long, uninterrupted programming walkthroughs.

\*Practically unlimited rather than a service-imposed recording cap—you'll eventually hit available storage or filesystem limits.

If your priority is long coding walkthroughs + no annoying file-size/recording caps + low cost, I’d go with OBS Studio.

🥇 OBS Studio — my recommendation

OBS Studio is free/open-source and has no recording-time limit or watermark. It records locally, so you're not constrained by a cloud-storage quota or a platform's maximum upload size. www.tella.com

For coding walkthroughs, I'd configure it roughly like this:

• 1080p / 30 fps — plenty for code and substantially smaller than 60 fps.
• MKV recording format — safer if your computer crashes during a long recording.
• Use OBS's Remux Recordings afterward if you need MP4.
• Hardware encoder if your GPU supports it.
• Record mic + desktop audio on separate tracks if you plan to edit.
• Consider AV1 if your hardware supports it; it can give you smaller files at comparable quality. www.captio.work

The important distinction is that "no file-size limit" doesn't mean tiny files. A 4-hour 1080p recording can still be several GB depending on your bitrate. With OBS, you control that tradeoff rather than a SaaS provider imposing a quota.

If you hate OBS's interface

ShareX is an excellent Windows alternative: free, open-source, and unlimited. sharerec.com

ScreenRec is worth considering if your main goal is record → get a shareable link. It supports unlimited recording, although you're then relying more on its cloud workflow. sharerec.com

I would not choose Loom for this particular use case. Its free tier is oriented toward short async videos rather than multi-hour coding sessions. www.captio.work

My budget setup

$0: OBS → local recording → DaVinci Resolve/free editor for cuts → YouTube/unlisted or your own storage.

Mac + willing to spend: Screen Studio is much nicer for polished coding tutorials, with automatic cursor/camera effects, but OBS is the better value if you're primarily concerned with unlimited long recordings.

If you tell me Windows/macOS/Linux + your CPU/GPU + typical walkthrough length (e.g. 2–6 hours), I can give you an OBS configuration optimized for small files while keeping code text crisp.

For long coding walkthroughs (1–4+ hours) without running into recording caps or expensive plans, I’d prioritize local recording tools over Loom-style apps. Cloud recorders often impose time, storage, or export limits. ShareRec StreamYard

Best budget picks

🥇 OBS Studio — best overall

Cost: Free
Limits: No recording length limit (you’re mainly limited by disk space and hardware) StreamYard
Platforms: Windows, macOS, Linux

Why it’s ideal for coding tutorials:

• Records your entire IDE, terminal, browser, and webcam
• Separate audio tracks (mic vs system audio)
• Excellent quality-to-file-size ratio if configured correctly
• Saves locally, so no cloud storage fees
• Can record directly to MKV to avoid losing a long session if something crashes, then convert to MP4 afterward Captio

Good starter settings:

• Resolution: 1080p
• FPS: 30
• Encoder: Hardware encoder if available (NVENC/AMF/VideoToolbox)
• Format: MKV
• Bitrate: ~6,000–10,000 Kbps for coding content

Typical file sizes:

• 1 hour at 8 Mbps ≈ 3.6 GB
• 4 hours ≈ 14–15 GB

🥈 ShareX — best lightweight Windows option

Cost: Free
Limits: No recording cap Captio

Great if you:

• Use Windows
• Want quick captures
• Need annotations, screenshots, blur tools, arrows, etc.

Less ideal for:

• Multi-camera setups
• Polished course-style videos

🥉 ScreenRec — easiest “record and share”

Cost: Free tier available
Strength: Quick sharing after recording Captio

Good for:

• Sending walkthroughs to teammates
• Bug demonstrations
• Short-to-medium tutorials

For a 5-hour programming course, I’d still choose OBS.

Cheap paid options worth considering

Camtasia

Best if you want:

• Built-in editing
• Zoom effects on code
• Cursor highlighting
• Callouts and captions

It’s much easier than a full OBS + editor workflow, but costs more.

ScreenFlow (Mac)

Similar idea:

• Record
• Edit
• Add effects
• Export a finished tutorial

File size tricks that matter for coding videos

Coding recordings compress extremely well because most of the screen is static.

Use:

• 1080p instead of 4K
• 30 FPS instead of 60 FPS
• Hardware encoding
• H.264 or H.265/HEVC
• Avoid recording your whole 4K monitor if viewers only need the editor

For example:

• Raw 4K/60 capture can create huge files
• A tuned 1080p/30 OBS recording can cut storage by 5–10× while still looking excellent for code

My recommendation by scenario

• Making a YouTube coding series/course: OBS Studio + DaVinci Resolve
• Recording client demos: OBS Studio or ScreenRec
• Fast internal team walkthroughs: ScreenRec or a Loom alternative
• Mac with budget for convenience: ScreenFlow
• Zero budget, maximum reliability: OBS Studio

For long coding walkthroughs, OBS is the one I’d start with. The main “file size limit” becomes your hard drive rather than the software. StreamYard

If your priority is long coding walkthroughs + very low cost + no arbitrary recording/file-size cap, my pick is OBS Studio.

Best options

1. OBS Studio — best value by far

OBS Studio

It's free/open-source and records directly to your own drive, so there's no subscription upload quota or service-imposed video limit. OBS specifically recommends MKV for recording because an interrupted recording remains recoverable rather than potentially destroying the entire file. You can then remux it to MP4 without re-encoding. obsproject.comgetsharex.com

For coding tutorials, I'd use:

• 1080p / 30 fps — plenty for most code
• Hardware encoder if your GPU supports one
• MKV recording
• Separate microphone/audio track if you plan to edit
• Record to an NTFS/APFS/ext4 drive rather than FAT32

That last point matters: a FAT32 drive has a ~4 GB per-file limit, which can look like an OBS file-size problem even though OBS itself isn't imposing the limit. obsproject.com

OBS also supports multiple audio tracks, which is useful if you want your microphone, system audio, etc. independently editable later. obsproject.com

2. ShareX — great if you're on Windows and want simplicity

ShareX

It's free/open-source and supports screen recording, but I'd still choose OBS for multi-hour coding courses. ShareX is more of a general capture/productivity tool; OBS gives you much better control over encoding, audio, scenes, sources, and recording quality. getsharex.com

3. Camtasia — worth paying for if editing matters

Camtasia

Camtasia is considerably nicer if you're producing finished courses: zooming into code, callouts, cursor effects, cuts, captions, etc. Its current online recorder can record screen/camera/mic and edit/share in the browser. camtasia.techsmith.com

But for your specific requirement—long recordings without file-size limits on a budget—I'd spend the money elsewhere and use OBS + a cheap local SSD.

My recommended cheap setup

OBS → local SSD → DaVinci Resolve/Kdenlive for editing → YouTube

The important distinction is that recording locally eliminates the cloud-storage/file-upload limitation. A 3-hour recording might be many GB, but that's only a problem if your storage is limited.

Also, don't use OBS's Lossless preset unless you have a very specific reason: OBS says it can consume roughly 7 GB per minute. obsproject.com

For coding walkthroughs, 1080p30 + hardware H.264/HEVC/AV1 + sensible quality setting should give you dramatically smaller files while keeping text sharp.

Bottom line: If you're trying to spend $0/month, use OBS Studio. If you tell me Windows/macOS/Linux, typical walkthrough length (e.g. 2–6 hours), and whether you're uploading to YouTube, I can give you the exact OBS settings I'd use for sharp code with minimal file size.

For long coding walkthroughs (1–8+ hours) where you don’t want to hit recording limits or pay much, I’d focus on local recording software rather than cloud-first tools. Cloud tools often impose upload/storage caps or clip limits. toolradar.comtoolradar.com

Best budget picks

toolradar.comvidiopicks.net

My recommendation: OBS Studio + good encoding settings

For coding walkthroughs, OBS is usually the sweet spot:

• No subscription
• No watermark
• No file-size ceiling imposed by the app
• Works on Windows, macOS, and Linux
• Can record screen + microphone + webcam + a second monitor
• You choose the quality/file size tradeoff toolradar.com

A practical setup:

• Resolution: 1920×1080
• FPS: 30
• Encoder: hardware encoder if available (NVENC/AMF/Quick Sync)
• Format: MKV while recording (safer if OBS crashes), then remux to MP4
• Bitrate: around 5,000–8,000 kbps for readable code

Typical storage:

• 1080p coding tutorial: roughly 2–4 GB/hour depending on settings
• 8-hour session: roughly 16–32 GB

Avoid for this use case

• Loom free tier — great for quick demos, but not designed for multi-hour tutorials because of recording limits. toolradar.com
• Browser-only recorders that upload immediately — your bottleneck becomes upload speed and cloud storage.

A cheap creator workflow

1. Record with OBS.
2. Edit with DaVinci Resolve (free version is enough for many tutorials).
3. Store raw recordings on an external SSD or large HDD.
4. Export final videos in H.264/H.265 for upload.

If you’re making YouTube-style coding courses, I’d pick OBS + DaVinci Resolve. If you’re recording private client walkthroughs, I’d lean toward OBS + a cloud storage service after export.

If your priority is long coding walkthroughs without hitting a recording/file-size cap, I’d strongly favor local recording software over Loom-style cloud recorders.

My picks

1. OBS Studio — my recommendation

OBS Studio official site

For coding tutorials, OBS is hard to beat: it's free, open source, works on Windows/macOS/Linux, and records locally, so there isn't a service-imposed 5- or 10-minute limit. obsproject.com

The important distinction is that your disk space becomes the limit, rather than the software or subscription. For example, a 2–3 hour coding walkthrough can simply be one large local recording.

I'd configure it roughly like:

• 1080p / 30 fps — plenty for code and substantially smaller than 60 fps
• Hardware encoder if your GPU supports it
• MKV recording for crash protection
• Remux to MP4 afterward if you need broad editing/upload compatibility

OBS specifically recommends MKV because an interrupted recording remains recoverable; you can then remux it to MP4 without re-encoding. obsproject.comtoolradar.com

2. ShareX — great if you're on Windows

ShareX official site

Also free/open source and has no recording-time cap. It's particularly nice if you want quick screen captures, annotations, GIFs, screenshots, and occasional video rather than building a sophisticated recording setup. sharerec.com

For serious multi-hour walkthroughs, though, I'd still choose OBS.

3. Screen Studio — if you're on Mac and want polish

This is the option I'd consider if you're willing to spend some money to make coding videos look much more professional automatically—smooth cursor movement, zooms, etc.

It's substantially more convenient than OBS for presentation-oriented tutorials, but OBS wins on budget.

One thing I'd avoid

Loom is excellent for sending a quick "here's what I did" video to a coworker, but it's not what I'd pick for a library of long coding walkthroughs. Free-tier recording limits make it poorly suited to your use case. toolradar.com

The real budget trick

Don't optimize primarily for the software's file-size limit. Optimize the video bitrate/codec and buy cheap storage.

For coding, I'd rather have:

OBS → 1080p30 → hardware H.264/HEVC → local SSD → edit/upload afterward

than pay $10–20/month for cloud recording.

If you're recording 10–20+ hours of tutorials per month, OBS is especially compelling because you're essentially paying $0 for the recorder and only for storage you actually consume.

If you tell me Windows or Mac + your CPU/GPU + whether you're recording webcam/mic too, I can give you the exact OBS settings I'd use for sharp code text with the smallest reasonable file sizes.

For long coding walkthroughs, I’d strongly favor local recording over cloud-first tools. That avoids artificial 5–60 minute limits and cloud storage quotas.

Best budget picks

🥇 OBS Studio — my recommendation

OBS Studio is probably the best answer if your priority is “record 2–4 hour coding sessions without paying based on video length.”

• Free and open source
• Windows, macOS, Linux
• No recording-time quota
• No watermark
• Can capture your IDE, terminal, browser, webcam, microphone, etc.
• Excellent control over bitrate/quality
• Can record separate audio tracks, which is useful for coding tutorials. obsproject.com

For long recordings, I'd use MKV rather than ordinary MP4. OBS specifically recommends MKV because an interrupted recording is recoverable; you can then remux it to MP4 afterward without re-encoding. obsproject.comscreen.studioobsproject.com

Important: “No file-size limit” doesn't mean files are tiny. A 3-hour 1080p recording can still be several GB. Your limiting factor becomes disk space, not the software.

🪶 ShareX — great if you're on Windows

ShareX is another free/open-source option. It's especially nice if you mostly want straightforward screen capture rather than OBS's elaborate scene/streaming setup. Current comparisons list it as having no recording cap. sharerec.com

I'd still pick OBS for coding walkthroughs, though, because you'll probably appreciate multiple sources/audio tracks once your setup gets more sophisticated.

🍎 Screen Studio — worth paying for on Mac

Screen Studio is much nicer if your goal is “record my coding session and have it look polished with minimal editing.” It's designed specifically around tutorials, courses, and product demos. screen.studio

But for a strict budget, OBS wins.

What I'd actually use

For a coding YouTube/course workflow:

OBS → local MKV → edit in DaVinci Resolve → upload wherever you want.

That gives you no recorder subscription, no recording-length limit, and no cloud-storage dependency. OBS also supports hardware encoders including AV1/HEVC/H.264, so if your GPU supports them you can get better compression without hammering your CPU. obsproject.comscreen.studioobsproject.com

One thing I'd avoid for this particular use case: Loom-style cloud recorders. They're fantastic for quick async messages, but they're generally the wrong architecture when you're deliberately making multi-hour recordings and don't want storage/length limits.

If you tell me Windows or Mac + your GPU/CPU, I can give you the exact OBS settings for long 1080p coding recordings with reasonably small files.

For long coding walkthroughs on a budget, you want something that avoids recording time limits, cloud storage caps, and giant file uploads. The best options are usually local recording tools, where your only limit is your hard drive space. streamyard.com

🥇 Best overall: OBS Studio (Free)

Best for: 30-minute to multi-hour coding tutorials, YouTube courses, programming streams

Pros

• No recording length limit
• No watermark
• Works on Windows, macOS, Linux
• Excellent control over:
  • screen capture
  • microphone
  • webcam
  • multiple monitors
  • audio tracks
• Can record directly to efficient formats (MKV recommended)

Cons

• Takes ~15 minutes to configure well
• You manage your own files/uploads

Budget setup

• Record in 1080p
• Use H.264 hardware encoding (NVENC/Quick Sync/AMD AMF if available)
• Record to MKV, then remux to MP4 inside OBS if needed

A 2-hour coding session can often be kept to a few GB instead of tens of GB with sensible bitrate settings.

🥈 Best Windows lightweight option: ShareX (Free)

Best for: quick tutorials, bug demos, annotated explanations

Pros

• Free and open source
• No recording cap
• Built-in annotation tools
• Very lightweight

Cons

• Windows only
• Not as polished for full course-style videos

sharerec.com

🥉 Best if you want editing included: CapCut Desktop (Free tier)

Best for: coding videos that need:

• zoom-ins
• captions
• cuts
• highlights

Workflow:

1. Record with OBS
2. Edit in CapCut
3. Export for YouTube/course platforms

Tools I would avoid for long coding walkthroughs

My recommended cheap workflow

Recording

• OBS Studio
• 1080p / 30fps
• 8–12 Mbps bitrate
• Separate mic audio track

Storage

• Save locally
• Upload finished videos to:
  • YouTube unlisted (free)
  • Google Drive
  • Backblaze B2 if you build a large archive

Audio matters more than video
For coding tutorials, a $30–$70 USB microphone upgrade usually improves perceived quality more than recording at 4K.

If you are making YouTube coding tutorials, paid courses, or just private walkthroughs for your team, the ideal setup changes a bit.

If your priority is long coding walkthroughs without cloud/file-size limits, I’d strongly favor local recording software over browser-based recorders.

My picks

🥇 OBS Studio — best choice

OBS Studio is what I'd use for serious coding walkthroughs. It's free, records directly to your disk, and doesn't impose a service-level file-size cap. It supports hardware encoders such as NVENC, AMD AMF, Intel QSV, and Apple VideoToolbox, which can substantially reduce the CPU hit while you're coding. obsproject.com

For walkthroughs, I'd use:

• 1080p / 30 fps
• MKV recording
• Hardware H.264 or HEVC/AV1 encoder if your machine supports it
• ~8–12 Mbps video bitrate for 1080p30
• 128–160 kbps microphone audio
• Record to a dedicated SSD

OBS recommends MKV because an interrupted recording is recoverable rather than potentially destroying the entire file. You can remux it to MP4 afterward. obsproject.com

At 10 Mbps, you're looking at roughly 4.5 GB/hour of video, so a 1 TB drive gives you well over 200 hours of raw footage before accounting for other files.

🥈 ShareX — excellent if you're on Windows

ShareX is also completely free/open-source and includes screen recording through FFmpeg. github.com

It's particularly nice if you want something lightweight and don't need OBS's elaborate scene/audio setup. It gives you control over encoding and recording settings, including hardware encoding. sharex.best

For coding tutorials specifically, though, I'd still pick OBS because its scene system makes it easier to have:

IDE + webcam + microphone + optional second monitor + terminal

all configured exactly how you want.

🥉 ScreenToGif

ScreenToGif is free/open-source and can record a selected region and export to video, with a built-in editor. github.com

It's fantastic for small coding demonstrations, bug reproductions, and clips where you want to remove individual frames. I wouldn't choose it as my primary tool for 2–4 hour walkthroughs.

What I'd spend the money on instead

Don't spend $100+ on recording software. Put the money into storage.

A 1 TB external SSD is currently available around the ~$75–$130 range depending on model/sale. For example:

PNY Pro Elite V2 1TB USB 3.2 Gen2x1 Type-C External Portable SSD

$74.00

That is a much better budget investment for your use case than paying for a recording service with upload/storage limits.

My ideal budget setup:

OBS Studio → 1080p30 → H.264 hardware encoding → MKV → 1 TB SSD → DaVinci Resolve/free editor afterward

One important thing: don't use OBS's Lossless preset for this. OBS says lossless recording can reach roughly 7 GB per minute. obsproject.com That's wildly unnecessary for a coding walkthrough.

If you tell me Windows/Mac/Linux + your GPU/CPU + typical walkthrough length (e.g. 2, 4, or 8 hours), I can give you the exact OBS settings to get small files while keeping code/text razor sharp.

For long coding walkthroughs on a budget, I’d pick OBS Studio.

Best options

🥇 OBS Studio — my recommendation

OBS Studio is free and doesn't impose a recording-duration or hosted-file-size limit because recordings are saved locally. It also gives you extensive control over resolution, FPS, encoder, bitrate/quality, and output format.

For coding specifically, I'd use:

• 1080p / 30 FPS — plenty for most IDE walkthroughs
• H.264, HEVC, or AV1 hardware encoding if your GPU supports it
• MKV recording format — OBS recommends it because an interrupted recording is much less likely to ruin the entire file
• Remux to MP4 afterward if you need compatibility with an editor. OBS has built-in remuxing. obsproject.com

The important distinction is that there isn't really a "file size limit" you need to work around with OBS. Your practical limit is your available disk space. You can also dramatically reduce file sizes by choosing an appropriate encoder/quality setting.

🥈 ShareX — best if you're on Windows

ShareX is also completely free and open source, with screen recording powered by FFmpeg. It provides control over codecs, quality, frame rate, and audio, so you can tune recordings for smaller files. getsharex.com

I'd choose OBS over ShareX for hours-long coding tutorials, though. OBS is more purpose-built for sustained video recording and gives you a better monitoring/scene/audio workflow.

🥉 ScreenPal — easiest cheap paid option

ScreenPal currently lists Deluxe at $4/month when paid annually, with unlimited recording, editing, and hosting. The free version is limited to 15 minutes per recording, so it doesn't meet your requirement unless you upgrade. screenpal.com

Bottom line: If you want $0 + hours-long recordings + no artificial file-size ceiling, use OBS Studio and save locally.

If you tell me whether you're on Windows, macOS, or Linux, I can give you the exact OBS settings I'd use for a 4–8 hour coding walkthrough while keeping the files reasonably small.

For long coding walkthroughs, I’d prioritize software that records directly to your drive rather than imposing cloud/file-size limits.

My picks

🥇 Best budget choice: OBS Studio.
It's free and records locally, so you're limited primarily by your disk space rather than a service's upload/file-size cap. OBS specifically recommends MKV for recording because an interrupted recording is less likely to corrupt the entire file. obsproject.com

For coding tutorials, I'd use OBS + H.264/HEVC/AV1 hardware encoding, 1080p30, and record to MKV. You can remux to MP4 afterward without re-encoding.

🥈 Best if you want simplicity: ScreenPal.
The free tier is capped at 15 minutes per recording, but Deluxe is currently $4/month when paid annually and removes the recording-time limit, with unlimited video hosting. obsproject.comscreenpal.com

ScreenPal pricing

What I'd choose for coding specifically

If you're making 1–3 hour programming walkthroughs, go with OBS. It gives you:

• No subscription
• No cloud upload requirement
• No artificial 15/30/60-minute recording limit
• Excellent screen/window capture
• Separate microphone/system-audio tracks
• Hotkeys for pause/stop
• Scene switching if you want webcam + code + slides
• Very good control over file size and quality

The main trick is encoding efficiently. A 3-hour 1080p coding recording doesn't need to be enormous because most of the screen is static code.

If you tell me Windows or Mac + your CPU/GPU + whether you want 1080p or 1440p, I can give you an OBS setup that targets something like ~1–3 GB per hour while keeping code crisp.

If your priority is long coding walkthroughs + no cloud/file-size limits + low cost, I’d go with OBS Studio.

Best options

🥇 My pick: OBS Studio

For coding specifically, OBS is hard to beat. It's free, records directly to your own drive, and doesn't impose a "your video is too large" cloud restriction. OBS itself recommends MKV for recording because an interrupted recording remains recoverable rather than potentially corrupting the entire file. obsproject.com

For a coding walkthrough, I'd use:

• 1080p / 30 fps — plenty for code
• AV1 or HEVC if your GPU supports hardware encoding
• MKV recording format
• Remux to MP4 afterward if you need compatibility
• Record mic + desktop audio separately if you expect to edit
• Keep recordings on a large SSD/HDD rather than uploading them during recording

OBS notes that its "High Quality" preset gives high quality at a medium file size, while lossless recording can be an enormous ~7 GB/minute, so don't use lossless for ordinary coding tutorials. obsproject.com

Download OBS Studio

If you want easy editing: Camtasia

TechSmith Camtasia 2024

$51.02

Camtasia is considerably nicer if your workflow is record → cut mistakes → zoom into code → add callouts → export. Its recorder can capture the entire screen, mouse paths, clicks and keystrokes, and its editor is designed around tutorials/software demonstrations. support.techsmith.com

The catch is price: TechSmith has moved Camtasia to annual subscriptions, so it's substantially less attractive if your main concern is budget. support.techsmith.com

If you're on Mac: ScreenFlow

Telestream ScreenFlow 10

$199.00

ScreenFlow is an excellent Mac-specific alternative, particularly if you want editing integrated with recording. The current version is 10.5.2, and Telestream lists it at $199. www.telestream.net

One important distinction

If by "file size limits" you mean the recording software itself, OBS/ScreenFlow/Camtasia aren't the problem—the limiting factor is basically your storage.

If you mean uploading the finished walkthrough somewhere, that's a different question. You could record a 3-hour walkthrough locally with OBS and then use a service/storage setup that doesn't choke on a huge file.

Bottom line:
$0 → OBS Studio.
Mac + want easy editing → ScreenFlow.
Want the easiest professional tutorial workflow → Camtasia.

If you tell me Windows or Mac + typical walkthrough length (e.g. 1–3 hours) + where you plan to upload it (YouTube, GitHub, private clients, etc.), I can give you the cheapest exact setup and recording settings.

For long coding walkthroughs on a budget, the main thing you want is no recording time cap + controllable file sizes. The best options are:

sharerec.com

My recommendation: OBS Studio

For multi-hour programming walkthroughs (React builds, debugging sessions, algorithm lessons, etc.), OBS is usually the sweet spot:

• No artificial recording limit
• Records locally (you own the files)
• Works on Windows, macOS, and Linux
• Lets you tune quality vs. size with bitrate and encoder settings quicksaasguide.tech

A practical setup:

• Resolution: 1080p
• FPS: 30 (coding does not need 60 FPS)
• Format: MKV while recording (safer if OBS crashes), then remux to MP4
• Encoder: hardware encoder if available (NVENC/AMF/Quick Sync)
• Bitrate: around 4,000–8,000 Kbps for readable code

Rough storage estimates:

• 1 hour at 4 Mbps → ~1.8 GB
• 1 hour at 8 Mbps → ~3.6 GB

If you want smaller files after recording, run them through:

• HandBrake (easy GUI)
• FFmpeg (more control)

Avoid for this use case

• Loom free tier — great for quick explanations, but not ideal for full coding courses because free plans have recording limits. streamyard.com
• Browser-only recorders — convenient, but long high-resolution sessions can become storage/upload headaches.

For a solo developer making YouTube tutorials or a course, I’d use OBS + a cheap external SSD for raw recordings + HandBrake for final exports. That gives you effectively unlimited recording length without paying a monthly subscription.

If your main requirement is long coding walkthroughs without file-size or recording-time caps, I’d go with OBS Studio.

My picks

OBS is particularly good because it records locally, so you're limited primarily by your available disk space rather than a cloud-service quota. OBS itself recommends MKV for recording because an interrupted recording is much less likely to lose the entire file; you can then remux it to MP4 without re-encoding. obsproject.com

For coding specifically: OBS wins

I'd configure it roughly like this:

• 1080p
• 30 fps — plenty for code and dramatically smaller than 60 fps
• Hardware encoder if your GPU supports one
• MKV recording
• Record screen/window + microphone
• Add a separate webcam source only if you actually need it
• Remux to MP4 afterward if your editor requires it

For example, at a reasonable recording bitrate, a 2-hour walkthrough can be only a few GB, rather than the enormous files you'd get from lossless/high-bitrate capture.

ShareX is my second choice if you're on Windows and want something lighter. It's free/open-source and includes screen recording, but OBS gives you substantially more control over audio, scenes, encoding and multi-hour recording workflows. getsharex.comsharerec.com

One important distinction

If by "file size limits" you mean you want to upload the finished walkthrough somewhere, that's a different problem. A recorder can have unlimited local recording while the hosting service imposes a 5 GB/10 GB/etc. upload limit.

For a budget coding-content workflow, I'd do:

OBS → local MKV → remux MP4 → DaVinci Resolve/free editor → YouTube or your preferred host

That gives you essentially $0 recording cost and no artificial recording-length limit. Current 2026 comparisons continue to rank OBS as the strongest free/unlimited option. sharerec.com

If you tell me Windows/Mac/Linux + your CPU/GPU + typical walkthrough length (e.g. 1–3 hours), I can give you an OBS configuration optimized for small file sizes while keeping code razor-sharp.
