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

My shortlist

1. OBS Studio — best overall

obsproject.com is free, open-source, and available on Windows, macOS, and Linux. It doesn't impose a cloud-storage-style recording limit because recordings are saved locally to your drive. OBS Studio OBS Studio

For coding tutorials, it's particularly good because you can record:

• Your IDE/editor
• Webcam
• Microphone
• System audio
• Multiple monitors
• Browser windows
• Terminal
• Separate audio tracks

For very long recordings, use MKV rather than directly recording to MP4. OBS specifically recommends MKV because an interrupted recording remains recoverable, and you can subsequently remux it to MP4 without re-encoding. OBS Studio OBS Studio

The important distinction is: there isn't a magical "unlimited file size" format. A 4-hour 1080p recording can still be several GB. But OBS doesn't impose a small artificial file-size/time ceiling; your practical limit is disk space and your encoding settings.

2. ShareX — great if you're on Windows

getsharex.com is also free/open-source and uses FFmpeg for recording. It lets you control codec, quality, frame rate, and audio, which gives you considerable control over file size. ShareX️ ShareX

I'd choose it if you want "select my coding window and hit record" rather than OBS's more elaborate production setup.

3. Camtasia — if editing matters

Camtasia is much more polished for record → edit → annotate → publish, but it's not my budget pick. Its current plans are paid, although its recording capability supports unlimited 4K/60fps recordings on some paid tiers. TechSmith Support G2

The setup I'd use for coding walkthroughs

For 1080p coding tutorials, I'd start with:

• OBS Studio
• 1920×1080
• 30 FPS rather than 60 FPS
• Hardware H.264/HEVC/AV1 encoder if your GPU supports it
• MKV recording
• Separate microphone audio track
• CQP/quality-based encoding rather than an unnecessarily high fixed bitrate
• Remux to MP4 afterward if needed

The 30 FPS choice is especially sensible for programming: your screen isn't changing nearly as rapidly as gameplay, so 60 FPS usually isn't worth doubling the recording workload/file size.

Bottom line: If your main concern is "I want to talk through code for 2–6 hours without some app telling me I've hit the recording limit," OBS Studio is the one I'd install. Your constraint becomes available disk space rather than a software recording quota. OBS Studio OBS Studio

If you tell me Windows/Mac + your GPU (e.g. NVIDIA/AMD/Apple Silicon), I can give you the exact OBS settings for small files while keeping text/code crisp.

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

My shortlist

• obsproject.com — best overall, free

• No recording-length or cloud-file-size limit; you're limited primarily by your available disk space.
• Excellent for coding: screen + webcam + microphone + separate audio tracks.
• Record to MKV, then let OBS remux it to MP4 afterward. OBS specifically recommends MKV because an interrupted recording doesn't destroy the whole file. OBS Studio OBS Studio
• Supports hardware encoders such as NVENC/AMD/Quick Sync and newer codecs including HEVC and AV1, which can reduce storage requirements. OBS Studio
• Cost: $0.
• screenstudio.dev — best if you're on Mac and want polished tutorials

• Particularly nice for coding walkthroughs because it automatically adds cursor movement/zoom, click effects, keystrokes, webcam bubbles, and basic editing. Screen Studio
• As of September 2026, its beta is free with no time or export limits. Screen Studio
• macOS 15+ only. Screen Studio
• getsharex.com — good free Windows alternative

• Free/open-source-style utility focused on capture rather than editing.
• Uses FFmpeg and supports MP4/WebM recording. ShareX️
• Less convenient than OBS if you want multiple scenes, webcam layouts, audio tracks, etc.
• techsmith.com — good paid option if editing matters

• TechSmith currently lists a Starter plan at $39/year, including unlimited 4K/60fps recordings; more advanced editing is in the substantially more expensive tiers. TechSmith
• Better suited if you want to record, cut mistakes, add callouts/zoom effects, captions, etc. in one application.

What I'd use for your specific case

OBS + local recording + 1080p30 + hardware H.264/HEVC/AV1 encoder.

For coding, 30 fps is usually plenty and substantially reduces storage compared with 60 fps. OBS's own documentation notes that higher-quality/lossless settings can create enormous files; its lossless preset can be around 7 GB per minute. OBS Studio

A practical starting point:

Important distinction: there isn't really a magic "no file size limit" recorder. With local recording, the constraint becomes your disk capacity rather than an application's upload/file-size limit.

If you're doing 2–6 hour programming tutorials, OBS is probably the most economical setup by a wide margin.

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

Best options

🥇 My pick: OBS Studio

obsproject.com

For what you're describing, OBS is probably the answer. It's free, records directly to your SSD/HDD, and doesn't impose a platform upload quota or recording-duration subscription limit. OBS specifically recommends MKV for recordings because an interrupted recording remains recoverable, and you can automatically/remotely remux it to MP4 afterward. OBS Studio OBS Studio

For coding walkthroughs, I'd use roughly:

• Resolution: 1080p
• FPS: 30
• Encoder: hardware encoder if your GPU supports it
• Rate control: CQP/quality-based encoding
• Quality: around CQ 20–24 as a starting point
• Container: MKV
• Audio: 160–192 kbps AAC
• Then: remux MKV → MP4 if your editor requires it

OBS notes that quality-based encoding lets bitrate vary according to what's on screen, which is particularly useful for relatively static content like a code editor. OBS Studio OBS Studio

Important: don't use OBS's lossless setting unless you really need it—it can produce roughly 7 GB per minute. OBS Studio

🥈 If you're on Mac: Screen Studio

screen.studio

This is much nicer than OBS if your goal is polished coding tutorials rather than raw screen capture. It automatically zooms toward your cursor, smooths cursor movement, can record mic/system audio and webcam, and has built-in transcript/subtitle features. Screen Studio Screen Studio

The downside is cost: it's subscription software, whereas OBS is completely free.

🥉 Windows: ShareX

getsharex.com

If you want something extremely lightweight and don't care about fancy tutorial effects, ShareX is worth considering. But for multi-hour coding walkthroughs, I'd still choose OBS because its recording controls and encoder configuration are much better suited to this use case.

What I'd actually use

For a budget coding channel/course:

OBS → local MKV → DaVinci Resolve → final MP4

That gives you effectively unlimited recording length, limited mainly by your available disk space rather than a software subscription.

If you tell me Windows or Mac + your GPU/CPU, I can give you the exact OBS settings I'd use for 1–3 hour coding recordings while keeping the files reasonably small.

If your priority is long coding walkthroughs, no artificial recording-length/file-size cap, and low cost, I’d strongly favor local recording software over browser-based tools like Loom.

My picks

1. OBS Studio — best overall

• Free and open source.
• Excellent for hours-long recordings.
• Records directly to your drive, so there’s no cloud upload/file-size quota imposed by OBS.
• You can use MKV for safer long recordings and automatically split recordings by time or size. OBS Studio
• Excellent audio controls: mic, system audio, separate tracks, etc.
• Supports hardware encoders such as NVENC/AMF/QSV, which can make long recordings relatively storage-efficient.

For coding walkthroughs, this is the one I'd choose.

2. ShareX — best lightweight Windows option

• Free/open source and uses FFmpeg for recording.
• Supports MP4/WebM and configurable codecs, bitrate, frame rate, and quality. ShareX️
• Great if you basically want "record my IDE + microphone" without OBS's production-oriented interface.
• I'd still choose OBS for multi-hour sessions, but ShareX is wonderfully simple.
• ScreenToGif — great for short coding demos, not my choice for hours

• Free and very convenient for recording a region/window.
• Can export to MP4/MKV/WebM and other formats. Softpedia
• But its own documentation has historically recommended more advanced software for hours-long fullscreen recordings. GitHub

The setup I'd use

For a 2–6 hour coding walkthrough, I'd do:

OBS → MKV → 1080p → 30 fps → hardware H.264/HEVC encoder → separate mic/system-audio tracks

Then have OBS automatically split the recording every 1–2 hours. That gives you manageable files rather than one enormous video, while avoiding a service's upload/file-size limit. OBS Studio

For coding specifically, you don't need 60 FPS. 30 FPS is plenty, and reducing resolution to 1080p (or even 720p if text remains readable) can dramatically reduce storage.

Bottom line:
OBS Studio > ShareX > ScreenToGif for your use case. If you're recording genuinely long programming sessions, I'd skip cloud-first recorders and keep the master files locally.

If you tell me Windows/macOS/Linux + how many hours per recording + whether you need webcam, I can give you an exact OBS configuration that keeps the files small while keeping code text crisp.

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

Best picks

• obsproject.com — Best overall / $0

• Free and open source.
• Excellent for 2–8+ hour coding sessions.
• Your recording size is basically limited by your available disk space, not an imposed cloud/file limit.
• Supports hardware encoding (NVENC, AMD, Intel, Apple) to keep file sizes reasonable.
• You can record directly to MKV, which is safer for very long sessions; if OBS or your computer crashes, the recording is much more recoverable than a traditional MP4. You can then remux it to MP4 without re-encoding. OBS Studio OBS Studio
• Recent OBS versions also have Hybrid MP4, which combines broad MP4 compatibility with crash resilience. OBS Studio
• screen.studio — Best if you're on Mac and want polished tutorials

• Much nicer out-of-the-box presentation: cursor effects, zooms, etc.
• Currently listed at about $9/month billed yearly or $29/month monthly. Screen Studio
• I'd choose it if you're making polished public tutorials rather than simply recording your development sessions.

What I'd use for coding

OBS + hardware H.264/HEVC/AV1 + 1080p/30fps is the budget sweet spot.

For example, roughly:

Don't use OBS's Lossless preset—it can generate around 7 GB per minute, which is obviously enormous. OBS Studio

For a coding walkthrough, I'd rather have a 100–300 MB/hour-ish efficient recording than a gigantic near-lossless file. The exact size depends heavily on your encoder, resolution, screen activity, and quality setting.

My recommendation: start with OBS Studio. It's hard to beat when "long recordings + no artificial limits + $0" are the requirements. If you tell me Windows/Mac/Linux + your GPU/CPU + whether you want webcam/mic, I can give you the exact OBS settings I'd use for coding walkthroughs.

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

Best options

• 🥇 OBS Studio — best overall, especially for long recordings

• Free and open source.
• Records directly to your drive, so there’s no SaaS upload quota or cloud recording limit.
• Excellent for 1–4+ hour coding sessions, multiple monitors, webcam, mic, and system audio.
• Use MKV as the recording container; OBS specifically recommends it because an interrupted recording is much less likely to become unusable. You can remux it to MP4 afterward. OBS Studio OBS Studio
• Best choice if you're on Windows, macOS, or Linux.
• 🥈 ShareX — best ultra-budget Windows option

• Completely free/open source with no subscription or account required. ShareX
• Supports screen recording and saving recordings locally.
• Much simpler than OBS if all you want is "record my screen + microphone."
• I'd choose it for straightforward coding demos where you don't need elaborate scenes/overlays.
• 🥉 Screen Studio — best polished Mac experience

• Currently its beta is free, with no time limit or export limit according to its September 2026 FAQ. Screen Studio
• Particularly nice for coding tutorials because it automatically handles things like cursor movement, clicks, zooms, keystrokes, webcam, and annotations.
• If you're on macOS, this is probably the easiest way to make recordings look professional without spending hours configuring OBS.
• Camtasia — best paid all-in-one editor

• More expensive, but the current Starter plan is $39/year and includes unlimited 4K/60fps recordings. TechSmith
• Makes more sense if you want to record and heavily edit the walkthrough afterward rather than simply capture it.

What I'd actually use

For long coding walkthroughs on a budget:

One important distinction: "no file-size limit" doesn't mean recordings are infinitely small. A 3-hour 1080p recording can still consume many GB depending on your encoder/bitrate. The advantage of OBS/ShareX is that you're limited primarily by your own storage, not a service's upload quota or recording-duration restriction.

For coding specifically, I'd start with OBS + AV1/HEVC hardware encoding if your GPU supports it, recording to MKV. OBS recommends hardware encoders for high-quality local recording and lists AV1 > HEVC > H.264 in terms of compression efficiency. OBS Studio

If you tell me Windows or Mac + your GPU/CPU, I can give you a good OBS configuration for hours-long coding recordings that stay reasonably small while keeping text/code crisp.

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

My ranking

1. OBS Studio — best overall

• Free, open source, no recording-time limit, no watermark. OBS Studio OBS Studio
• Windows, macOS, and Linux.
• Excellent for coding because you can capture your IDE, browser, terminal, webcam, mic, and separate audio sources.
• Crucially, there isn't an artificial file-size limit imposed by OBS. Your practical limit is your available disk space.
• It supports hardware encoding such as NVIDIA NVENC, AMD AMF, Intel QSV, and Apple VideoToolbox, which can substantially reduce CPU load while recording. OBS Studio
• Best choice if you're making 1–4 hour tutorials.
• ShareX — best lightweight Windows option

• Free and open source, with no recording-time cap. ShareX ShareX
• Particularly good if you just want to select your coding window/region and record.
• Less suitable than OBS if you want polished tutorials with multiple scenes, webcam layouts, overlays, etc.
• Windows only.
• ScreenRec — easiest if you want cloud sharing

• Useful if your priority is recording and immediately getting a shareable link.
• Current comparisons report unlimited recording, though cloud/account conditions apply. Captio
• I'd still choose OBS for serious long-form coding content because you retain the original files locally.

The important distinction: recording length vs. file size

If by "without hitting file size limits" you mean you don't want Loom-style restrictions, OBS is ideal. You're recording directly to your own drive rather than uploading to a service with a storage quota.

For example, roughly:

For coding, you can often get considerably smaller files because the screen doesn't change nearly as much as gameplay.

The OBS setup I'd use for coding

1080p / 30 FPS is usually the sweet spot. You don't need 60 FPS for typing code.

I'd also record to MKV, rather than directly to MP4. OBS recommends MKV because an interrupted/crashed recording won't normally destroy the entire recording; you can then remux it to MP4 afterward. OBS Studio OBS Studio

For the encoder, use your GPU's hardware encoder if available. OBS specifically recommends hardware encoding for good performance with relatively little CPU impact. OBS Studio

Bottom line:
If you're recording long programming tutorials/coding walkthroughs, I'd spend $0 on the recorder and use OBS Studio + a large SSD. That's a much better budget setup than paying monthly for Loom or similar services.

If you tell me Windows/Mac/Linux + your GPU/CPU, I can give you the exact OBS settings for small files while keeping code/text crystal clear.

For long coding walkthroughs, I’d prioritize software that records locally to your own drive. That avoids the annoying “you hit the 1-hour/2-hour/4 GB limit” problem that some cloud-first recorders impose.

My picks

• 🥇 OBS Studio — best overall, free

• Completely free and excellent for long recordings.
• Records directly to your disk, so there’s no cloud storage/file-upload limit.
• Supports MKV, which OBS specifically recommends because an interrupted recording is much less likely to destroy the entire file. OBS Studio
• Excellent for coding because you can capture your IDE, terminal, browser, webcam, microphone, etc. as separate sources.
• My recommendation if you're on a budget.
• 🥈 Camtasia — best if you want easy editing

• Much easier than OBS for editing mistakes out of a 2–4 hour walkthrough.
• Current Starter pricing is $39/year and includes unlimited 4K/60fps recording, although the editor is watermarked at that tier. The Essentials plan is $179.88/year and adds full editing capabilities. TechSmith
• Good choice if you're producing polished tutorials rather than just recording yourself coding.
• 🥉 ScreenToGif — excellent for short demos, not long walkthroughs

• Free/open source and can export to video. GitHub
• But its own documentation recommends using more advanced software if you're recording hours of fullscreen content, so I wouldn't pick it for your use case. GitHub

What I'd actually use

OBS Studio + local SSD + H.264/H.265/AV1 recording

For example:

OBS → 1080p → 30 fps → microphone + desktop → MKV → local SSD

A 1080p/30fps coding recording can be surprisingly manageable in size, particularly because an IDE/terminal has much less visual movement than gaming footage.

The important distinction is that “no file size limit” doesn't mean the file can literally be infinite—your practical limit is your available disk space and the filesystem. But you're no longer constrained by a software subscription's recording duration or cloud-upload limit.

For your specific use case, I'd pick OBS without hesitation. It's $0, handles multi-hour sessions, and gives you much more control over recording quality than most browser-based tools. OBS Studio

If you tell me Windows/macOS/Linux + typical walkthrough length (e.g. 2, 4, 8 hours), I can give you the exact OBS settings to get small files while keeping code text/crisp terminal output readable.

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

Best options

• 🥇 OBS Studio — best overall / essentially free

• Free and open source.
• No artificial recording-duration or cloud-storage limit; you're recording directly to your own drive.
• Excellent for 1–4+ hour coding sessions, with screen, webcam, mic, system audio, and multiple sources.
• Use MKV as the recording format. OBS specifically recommends it because an interrupted recording remains recoverable; you can automatically remux it to MP4 afterward. OBS Studio OBS Studio

• It's subscription-based, currently around $9/month billed annually or $12/month monthly according to its site. Screen Studio
• screen.studio
• 🥉 Camtasia — best integrated recorder + editor, but not my budget pick

• Strong editing workflow after recording.
• Its online version can record in the browser, but for lots of long recordings I'd still favor a local recorder like OBS. Camtasia

The key to avoiding huge files

There isn't really a magical "no file-size limit" recorder: long recordings necessarily consume disk space. The trick is using an efficient codec and reasonable quality settings.

For coding walkthroughs, I'd start with:

OBS → MKV → hardware H.264/HEVC/AV1 → 1080p60 or 1080p30 → quality-based encoding

Don't use OBS's Lossless setting—it can produce roughly 7 GB per minute, which is absurd for multi-hour tutorials. OBS Studio

For example, a 2-hour coding walkthrough encoded efficiently might be only a few GB rather than tens or hundreds of GB, depending on your screen content, resolution, codec, and quality setting.

My pick: If you're primarily recording VS Code/terminal/browser + your voice, OBS is the obvious budget winner. Spend the money on a large SSD rather than a recording service with cloud/file limits.

If you tell me Windows or Mac + your GPU/Apple chip, I can give you the exact OBS settings for ~1–3 GB/hour while keeping code text crisp.

For long coding walkthroughs on a budget, I’d avoid cloud-first recorders with storage caps. The best approach is usually: record locally → compress/export → upload wherever you want. QuickSaaSGuide

Best picks

Toolradar StreamYard## My recommendation by budget

$0 budget: OBS Studio

This is the one I’d pick for most developers.

A good setup:

• Record at 1080p / 30 FPS
• Use H.264 or H.265 hardware encoding if your GPU supports it
• Save as MKV while recording (safer if OBS crashes), then remux to MP4
• Split very long sessions into chapters (for example, 45–90 minute files)

OBS is free, open source, and designed for unlimited local recording rather than pushing you into storage plans. QuickSaaSGuide

Low-end laptop: ShareX (Windows)

If OBS feels heavy, ShareX is a simpler option for:

• IDE capture
• terminal demos
• short-to-medium walkthroughs
• quick annotations

Paid but efficient: Camtasia

Worth considering if you’re making:

• paid courses
• client training
• polished YouTube tutorials

The time saved in editing can justify the cost. Knowlify

Storage tips so files don’t explode

Typical sizes:

• 1080p coding walkthrough: ~1–5 GB/hour depending on settings
• 4K recording: can become tens of GB/hour

To keep files manageable:

• Use 30 FPS, not 60 FPS
• Use H.265/HEVC if your editor supports it
• Avoid recording your whole 4K monitor if viewers only need the IDE
• Record the IDE at a readable zoom (125–150%)
• Keep audio on a separate track if possible

A cheap “creator” workflow I’d use

1. OBS Studio → record screen + mic
2. DaVinci Resolve (free) → cut mistakes, add chapters
3. Upload to YouTube, course platform, or cloud storage

That combination gives you essentially unlimited recording length without paying monthly fees. stepvideo

If you tell me your OS (Windows/Mac/Linux), PC specs, and whether these are for YouTube, a course, or private docs, I can suggest exact OBS settings.

For long coding walkthroughs (1–5+ hours) on a budget, avoid cloud-first recorders with caps. You generally want local recording, a good codec, and control over bitrate so your files don’t explode. iTechGuides Tella

My recommendation for coding walkthroughs

🥇 Best value: OBS Studio + H.264/H.265 recording

Use OBS if you are making:

• YouTube programming tutorials
• Udemy-style courses
• live coding sessions
• long debugging sessions

A good setup:

• Canvas: 1920×1080
• FPS: 30
• Encoder: hardware H.264 (NVIDIA NVENC / AMD AMF / Intel QSV if available)
• Format: MKV (safer if OBS crashes), then remux to MP4
• Bitrate: - 1080p coding: ~5–8 Mbps
• 1440p coding: ~8–15 Mbps

Approximate file sizes:

• 1080p coding at 6 Mbps → ~2.7 GB/hour
• 1080p coding at 3 Mbps → ~1.35 GB/hour

Text-heavy IDE footage compresses very well, so you can often go lower than gaming settings.

Cheapest “serious creator” workflow

OBS Studio → DaVinci Resolve (free editor)

• OBS handles unlimited recording.
• Resolve handles cutting mistakes, adding zooms, captions, and chapters.
• Store raw recordings on a large HDD/SSD.

This avoids subscriptions entirely.

Tools I would avoid for multi-hour coding

• Loom — great for quick explanations, but free tiers are designed around shorter sharing workflows rather than huge archives. iTechGuides
• Browser-only recorders — they often introduce upload/storage limits.
• Very high bitrate “maximum quality” presets — IDE text does not need them.

If you want the simplest setup

My ranking:

1. OBS Studio — best overall, free, no practical recording limit. Tella
2. OBS + DaVinci Resolve — best free YouTube/course workflow.
3. Camtasia — pay for convenience if editing time matters more than money. ScreenStory

If you tell me your OS (Windows/Mac/Linux), target platform (YouTube/course/private), and whether you need webcam + mic, I can suggest exact settings.

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

• But it's subscription software, so OBS wins if minimizing cost is the priority.

The setup I'd use for coding

OBS + hardware encoder + local recording.

For a typical 1080p coding tutorial, I'd start around:

• Resolution: 1920×1080
• FPS: 30 fps
• Encoder: NVENC/AV1 if your NVIDIA GPU supports it; otherwise Apple VideoToolbox, AMD, or Intel Quick Sync as appropriate
• Rate control: CQP/quality-based recording rather than an unnecessarily high fixed bitrate
• Container: MKV
• Audio: 160–192 kbps AAC
• Separate audio tracks: mic + desktop audio, if you plan to edit afterward

OBS's own documentation recommends hardware encoding where available and gives CQP as an advanced recording option.

One important point: don't use OBS's Lossless preset for this. OBS says it can produce roughly 7 GB per minute—massive files.

If you tell me Windows/Mac/Linux + your GPU/CPU, I can give you the exact OBS settings I'd use for 2–4 hour coding walkthroughs with small files but crisp text.

For long coding walkthroughs, I’d strongly recommend OBS Studio. It’s free, has no artificial recording-duration/file-size limit, and is much better suited to 1–4+ hour technical recordings than most “easy” screen-recording apps. OBS Studio OBS Studio

My picks

• 🥇 OBS Studio — best overall / $0

• Excellent for VS Code + terminal + browser + webcam/mic.
• Record directly to your own drive, so there’s no cloud upload or subscription storage ceiling.
• Use MKV for recording; it’s designed to remain recoverable if the recording gets interrupted. You can automatically remux it to MP4 afterward. OBS Studio
• For a coding walkthrough, I'd start with 1080p30, H.264 hardware encoding, CQP ~20–23. OBS recommends CQP/CRF-style recording rather than CBR when recording locally. OBS Studio

• screentogif.com
• 🥉 ShareX — excellent free utility

• Great if you want screenshots, quick captures, and lightweight recording alongside your normal development workflow.
• getsharex.com

The important part: storage, not the recording software

There isn't really a meaningful “file-size limit” with OBS—the practical limit is your available disk space. File size is largely determined by bitrate/quality settings.

For example, at 10 Mbps, approximately:

• 1 hour = 4.5 GB
• 2 hours = 9 GB
• 4 hours = 18 GB
• 8 hours = 36 GB

For coding, you can often get away with a relatively modest bitrate because the screen isn't changing as rapidly as gameplay.

If your laptop's internal drive is small, recording to an external SSD is a very inexpensive solution. For example:

• SanDisk 1TB Extreme External Portable SSD - $119.00 (Walmart)

A 1TB SSD gives you roughly 50–100+ hours of 1080p recordings depending on your OBS quality settings, before accounting for other files.

What I'd personally use

OBS → 1080p/30 → hardware H.264 → CQP 22 → MKV → external 1TB SSD → automatically remux to MP4.

That gives you a cheap setup with essentially no software-imposed duration limit, good quality for reading code, and much less risk of losing a multi-hour recording if something goes wrong. OBS Studio OBS Studio

If you tell me Windows/Mac/Linux + your GPU (NVIDIA/AMD/Intel/Apple), I can give you the exact OBS settings for smallest practical file size while keeping code crisp and readable.

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

My picks

1. OBS Studio — best overall

• Free and open-source.
• Excellent for multi-hour coding sessions.
• No subscription or cloud-storage quota; recordings go directly to your drive.
• Great control over resolution, FPS, bitrate, microphone, webcam, multiple monitors, etc.
• For long recordings, use MKV while recording, then remux to MP4 afterward. This avoids losing the entire recording if something interrupts the file.
• Particularly good if you're recording VS Code + terminal + browser + narration.

Best choice if: you want maximum control and don't want to pay.

2. ShareX — best lightweight Windows option

• Free and open-source, with screen recording built in. ShareX GitHub
• Uses FFmpeg and supports recording regions/windows/full screens. ShareX️
• Much simpler than OBS if you just want to hit Record and capture your coding session.
• Local files mean you're not constrained by an online service's upload limit.

getsharex.com

3. Camtasia — best paid/easy option

• Much nicer if you want to edit the walkthrough afterward—cursor effects, callouts, audio editing, captions, etc.
• Its current Starter plan advertises unlimited 4K/60fps recordings and costs $39/year, although the included editor is watermarked; the Essentials tier is $179.88/year and includes the full editor. TechSmith
• Probably overkill if you're mainly recording raw coding sessions.

What I'd actually use

For a coding tutorial channel/course, I'd do:

OBS Studio → MKV recording → local SSD → edit in DaVinci Resolve/Kdenlive → export MP4

The important distinction is that "no file-size limit" doesn't mean the recording will be small. A 3-hour 1080p recording can easily be several GB depending on your bitrate/encoder. Your practical limit becomes available disk space, not the recording software.

For coding specifically, I'd use 1080p60 or 1440p30, a relatively modest H.264/H.265 bitrate, and prioritize crisp text. If you're recording primarily an IDE and terminal rather than gameplay, you can get surprisingly long recordings without enormous files.

Bottom line:

• 💰 $0: OBS Studio
• 🪶 Simplest Windows workflow: ShareX
• ✂️ Best if you want polished editing: Camtasia
• 🏆 My recommendation for your use case: OBS Studio

If you tell me Windows/Mac/Linux + desired resolution (1080p/1440p/4K) + typical walkthrough length, I can give you an OBS configuration that keeps a 3–6 hour coding walkthrough reasonably small while keeping code text sharp.

My picks

1. obsproject.com — best overall, free

• No subscription or recording-duration limit.
• Excellent for 1–4+ hour coding sessions.
• Can record your IDE, webcam, microphone, multiple monitors, etc.
• Use MKV as the recording format so an interrupted recording is much less likely to be ruined; OBS can remux it to MP4 afterward.
• You control the bitrate/quality, so the practical limit is your disk space, not an arbitrary file-size cap.
• Particularly good if you're comfortable spending 10 minutes configuring it once.
• getsharex.com — best lightweight Windows option

• Free/open-source and includes FFmpeg-based screen recording. ShareX️ GitHub
• Supports MP4/WebM recording and region/window/full-screen capture. ShareX️
• Great if you mostly want “record my coding window + microphone” without OBS's production-oriented interface.
• I'd still choose OBS for very long, important recordings.
• screentogif.com — great for short coding demos

• Free and open source, with video export and a built-in editor. GitHub GitHub
• I wouldn't make it my first choice for multi-hour walkthroughs; it's more oriented toward clips, demonstrations, GIFs, and detailed frame editing.
• techsmith.com — best paid/easy editor

• Much nicer if you want to edit the walkthrough afterward.
• Current TechSmith pricing lists $39/year Starter with unlimited 4K/60fps recordings, but the editor is watermarked; the editing-focused Essentials tier is $179.88/year. TechSmith
• For your specific goal, though, I'd save the money and use OBS + a free editor.

What I'd actually use

OBS → MKV → local SSD → DaVinci Resolve/free editor if needed → MP4

For coding specifically, I'd record at 1080p/30fps rather than 60fps. Text in an IDE doesn't benefit much from 60fps, and 30fps substantially reduces storage requirements.

As a rough example, at 8 Mbps, a 3-hour recording is around 10.8 GB. At 4 Mbps it's around 5.4 GB. So even very long walkthroughs are manageable with a reasonably sized SSD.

Bottom line: If your concern is specifically “I don't want my 2–4 hour coding walkthrough to hit some stupid file-size or duration limit,” get OBS Studio. It's free, local, and the limiting factor is essentially your available storage.

For long coding walkthroughs (1–6+ hours) on a budget, prioritize tools that record locally rather than cloud-first tools. File size limits usually come from cloud storage quotas, not the recorder itself. StreamYard

• Anything that uploads automatically unless you specifically want cloud hosting.

Cheapest practical workflow

Record:

• OBS Studio → local MKV files

Edit (optional):

• DaVinci Resolve free edition

Store:

• External 2–4 TB hard drive, or
• Cheap cloud backup after compressing

For a coding channel/course, a very solid $0 setup is:

OBS + DaVinci Resolve + external drive.

If you tell me your OS (Windows/Mac/Linux), GPU, and whether these are for YouTube, a course, or private notes, I can suggest exact OBS settings to minimize file size without making code blurry.

For long coding walkthroughs on a budget, I’d prioritize:

1. No recording time cap
2. No forced cloud storage limits
3. Good text/code readability
4. Reasonable file sizes
5. Recovery if a 3-hour recording crashes

My top picks:

🥇 Best overall: OBS Studio (Free)

obsproject.com

Best for: multi-hour programming tutorials, YouTube courses, bootcamp lessons.

Why it fits:

• Free forever
• No recording duration limits
• Saves directly to your own drive (so you aren’t fighting cloud caps)
• Supports hardware encoding (NVIDIA NVENC, Intel Quick Sync, AMD AMF) to reduce CPU load
• Can record screen + webcam + microphone + multiple audio tracks

OBS is the default recommendation for this use case because the only real limit is your disk space and hardware. OBS Studio Tech Journal

• A 10-hour course: ~40–80 GB

🥈 Easiest polished option: Camtasia

techsmith.com

Best for: paid courses where editing speed matters.

Pros:

• Recording + editing in one app
• Excellent callouts, zooms, cursor effects
• Easier than OBS

Cons:

• Expensive compared with free tools
• Large projects can become heavy

Good choice if you make tutorials professionally and value editing time more than minimizing cost.

🥉 Best Mac-only choice: Screen Studio

Best for: beautiful developer demos with minimal editing.

Pros:

• Automatic zooms and cursor emphasis
• Very clean output
• Great for SaaS demos and coding explainers

Cons:

• Paid
• macOS only

Avoid for long coding walkthroughs

Loom

loom.com

Great for:

• quick bug reports
• 5–10 minute explanations
• team messages

Less ideal for:

• 2-hour coding sessions
• building a course library

Free tiers tend to have recording/storage restrictions. StreamYard

My budget workflow recommendation

For a serious coding channel/course:

Recording

• OBS Studio

Audio

• Any decent USB microphone
• Noise suppression filter in OBS

Editing

• DaVinci Resolve (free version is very capable)

Storage

• Record locally to a large SSD
• Archive finished videos to a cheap external HDD or cloud storage

OBS settings I’d start with for coding tutorials

• Canvas: 2560×1440 if your monitor supports it
• Output: 1920×1080
• FPS: 30
• Encoder: NVENC/Quick Sync/AMF if available
• Rate control: CQP/CRF style quality mode rather than a fixed high bitrate when possible
• Quality target: around 20–23 for a good balance of clarity and size Francisco Gonzalez

Bottom line: install OBS Studio first. It is the best zero-budget choice for multi-hour coding walkthroughs. Add DaVinci Resolve later if you need editing.

For long coding walkthroughs on a budget, you want a recorder that:

• has no recording-length limit
• avoids artificial file-size caps
• can record hours of IDE + terminal + browser
• keeps file sizes reasonable
• doesn't require a subscription

My top picks:

🥇 Best overall: OBS Studio — Free

Best choice for serious coding tutorials, YouTube courses, or multi-hour sessions. It has no recording time limit, no watermark, and saves locally, so you are only limited by your disk space. Riverside Tech Journal

Why it fits coding walkthroughs:

• Record your whole screen, a specific monitor, or just VS Code/JetBrains
• Add microphone + webcam + system audio
• Pause/resume long recordings
• Hardware encoding (NVIDIA/AMD/Intel GPUs) can reduce CPU load
• Record directly to MKV (safer if OBS crashes), then convert to MP4

Recommended settings for coding:

• Resolution: 1080p
• FPS: 30 (60 is usually unnecessary for code)
• Encoder: NVENC/AMF/QSV if available; otherwise x264
• Bitrate: ~5–8 Mbps

A 2-hour coding session at 6 Mbps is roughly 5–6 GB, instead of enormous raw recordings.

🥈 Best lightweight option (Windows): ShareX — Free

Great if you mostly want screen capture without the production features. It supports long recordings without a built-in recording cap and is open source. FreeSoftwareX

Good for:

• quick coding demos
• bug reports
• internal tutorials
• lower-end laptops

Less ideal for:

• webcam overlays
• polished YouTube-style courses
• multi-scene setups

🥉 Best if you want easy sharing: ScreenRec

Useful if you record walkthroughs and immediately send links to teammates. It focuses more on quick sharing than advanced editing. ShareRec

Paid but worth considering: Camtasia

If you are making a paid course, Camtasia is much easier than OBS:

• built-in editing
• zoom effects for code
• cursor highlighting
• callouts
• annotations

But for a budget workflow, OBS + a free editor usually wins.

Avoid for long coding sessions

• Loom free tier — designed for short async clips, not multi-hour tutorials. Riverside
• Browser-based recorders — convenient, but cloud upload limits can become painful.
• Recording uncompressed/raw video — file sizes explode.

My recommended cheap workflow

1. Record with OBS Studio
2. Save as MKV
3. Convert to MP4 after finishing
4. Edit with: - DaVinci Resolve (free, powerful), or
5. Kdenlive (lighter)
6. Upload to YouTube/unlisted, Google Drive, or your preferred host

For most coding walkthrough creators, OBS + DaVinci Resolve is the closest thing to a professional setup for $0. Riverside

If you tell me your OS (Windows/Mac/Linux) and whether these are for YouTube, a course, or private team videos, I can suggest exact OBS settings and storage estimates.

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

My ranking

• 🥇 OBS Studio — best overall

• Free and open source.
• No cloud/file-size quota because recordings are saved directly to your drive.
• Excellent for 1–4+ hour coding sessions.
• Use MKV rather than MP4 while recording; OBS specifically recommends MKV because an interrupted recording remains recoverable. You can remux it to MP4 afterward. OBS Studio OBS Studio
• Supports hardware encoding including AV1, HEVC and H.264, which can dramatically reduce file sizes while maintaining quality. OBS Studio
• Best choice if you don't want to pay per minute, per recording, or for cloud storage.
• 🥈 Kdenlive — best if you also want free editing

• Free/open source and available on Windows, macOS and Linux. Kdenlive
• Has screen capture, although its capture functionality is less polished than OBS. Kdenlive Documentation
• Particularly good if you want to cut out pauses, mistakes, terminal fumbling, etc. afterward.
• 🥉 Camtasia — easiest polished workflow, but not my budget pick

• Very approachable for screen-recording + editing.
• Its current web version offers free recording without a watermark, but for a serious long-form coding workflow I'd still favor a local recorder like OBS. Camtasia

The setup I'd use

OBS → MKV → local SSD → Kdenlive/DaVinci Resolve for editing → MP4 for upload

For coding specifically, I'd record at 1080p/30 fps unless you genuinely need 60 fps. Text doesn't benefit much from 60 fps, and 30 fps substantially reduces storage requirements.

Also, don't confuse file-size limits with storage capacity. OBS itself isn't imposing a 2 GB/4 GB/10 GB upload-style limit; your practical limit is your drive/filesystem. For example, the old 4 GB problem people encountered with OBS was often caused by recording onto FAT32, which has a 4 GB file-size limit. OBS Studio

Bottom line: If you're recording 2–6 hour programming tutorials and want to spend essentially $0, OBS Studio is the one I'd choose. Set it to hardware H.264/HEVC/AV1 if your GPU supports it, record MKV, and you're good to go. OBS Studio

obsproject.com

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

My ranking

1. OBS Studio — best overall

• Free and open source.
• No recording-length or file-size limit imposed by the software; you're primarily limited by your disk space.
• Windows, macOS, and Linux.
• Excellent for recording VS Code/JetBrains + terminal + browser + webcam + microphone together.
• Hardware encoding can keep CPU usage reasonable.
• For long recordings, OBS recommends MKV because an interrupted recording is much less likely to destroy the entire file; you can remux it to MP4 afterward. OBS Studio OBS Studio
• obsproject.com
• ShareX — best if you're on Windows and want simpler

• Free/open source.
• No practical recording-length cap.
• Much lighter and less intimidating than OBS.
• Particularly good if you don't need webcam overlays or elaborate scenes.
• getsharex.com
• Current comparisons also consistently put it among the strongest free Windows options. ShareRec Redol
• ScreenRec — easiest if you want sharing rather than editing

• Long/unlimited recordings on its free offering, with cloud sharing.
• Windows/macOS/Linux.
• More convenient for sending a walkthrough to someone than managing large local video files.
• The tradeoff is that you're relying more on its cloud workflow. ShareRec Captio

What I'd actually use for coding

OBS + hardware H.264/HEVC/AV1 encoding + MKV recording.

For example, for a 1080p coding tutorial:

• Resolution: 1920×1080
• FPS: 30
• Encoder: your GPU's hardware encoder if available
• Quality: roughly CQP/ICQ 20–23 as a starting point
• Container: MKV
• Audio: 128–160 kbps AAC
• Remux to MP4 when finished if needed.

OBS specifically recommends quality-based recording controls such as CQP/ICQ and hardware encoders, and its documentation notes that AV1/HEVC can provide better compression than H.264 when your hardware supports them. OBS Studio OBS Studio

One important distinction: "no file-size limit" doesn't mean tiny files. A 4–8 hour 1080p walkthrough can still consume many GB. The advantage of OBS is that there isn't a SaaS upload quota or 5-minute/25-video free-tier restriction getting in your way—you control the files and storage.

If you're trying to make YouTube-length coding courses (2–10+ hours), I'd choose OBS without hesitation. If you tell me whether you're on Windows, Mac, or Linux and what GPU you have, I can give you an optimized OBS setup specifically for small files + crisp code text + clear voice.

For long coding walkthroughs on a budget, the best choice is usually software that records locally instead of uploading to a cloud service with duration/storage caps. OpenReplay Blog StreamYard

🥈 ShareX — best lightweight Windows option

Cost: Free
Best for: Windows developers who want simple capture

Pros:

• No time limits
• No watermark
• Very lightweight
• Can upload directly to your own storage destinations QuickSaaSGuide

Cons:

I would avoid for long coding walkthroughs

• Loom — excellent for quick demos, but free-tier limitations make it less attractive for multi-hour recordings. Tella
• Browser-only recorders — you’re depending on upload limits and browser stability.
• Lossless recording modes — coding screens compress extremely well, so they waste storage.

Cheap workflow I’d use

Recording:

• OBS Studio

Editing:

• DaVinci Resolve (free version)

Storage:

• External SSD or cheap large HDD
• Upload final videos to YouTube as unlisted/private if you need sharing

For a coding channel or course, OBS + DaVinci Resolve is probably the best $0 setup. Tella

If you tell me your OS (Windows/Mac/Linux), computer specs, and whether these are for YouTube, Udemy/course content, or private notes, I can suggest exact OBS settings to minimize file size.

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

🥉 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.
