ZoomCap vs OBS: Which Screen Recorder Should You Use?

OBS and ZoomCap both record your screen, and both keep the footage on your computer. After that they do different jobs. OBS is a capture and streaming engine. ZoomCap is a demo-video maker: it records and then does the part that usually happens afterwards, so the video is readable on a phone without an evening in an editor. We installed and used both for this post: OBS Studio from obsproject.com and ZoomCap's CLI and browser recorder. Our test method is published.

Why ZoomCap, in short

• Zooms placed for you. ZoomCap finds your clicks and bursts of typing and animates the frame there. With OBS you keyframe every zoom by hand in another app.
• Editing is mostly done when recording stops. The editor opens with zooms, a smooth cursor and your recording ready for a background, captions and music.
• Nothing to configure first. One command, or open /record in Chrome or Edge. No scenes, sources or encoder settings.
• $29 once. Pay once, keep it, with a 14-day refund.

ZoomCap vs OBS: not the same kind of tool

ZoomCap is a demo-video maker. It records, finds where you clicked and typed, glides the frame there, holds, releases, redraws the cursor, and opens the result in an editor ready to export as an MP4.

OBS Studio is a broadcast and capture engine. Scenes, sources, filters, audio mixers, encoders, live output to Twitch or YouTube: it exists to get pixels and audio out of your machine reliably.

So the fair comparison for a demo video is not OBS against ZoomCap. It's OBS plus an editor plus your evening against ZoomCap.

Side by side

Where ZoomCap wins

The zoom is the whole point. A raw screen recording of a 4K display, watched in a phone-sized player, is unreadable: the problem we wrote about in why screen recordings look bad. The fix is zooming to where the action is, and doing that by hand is the slowest part of editing a demo. ZoomCap detects clicks and typing bursts and animates for you. OBS has no equivalent; you crop and keyframe it yourself afterwards.

Typing-aware zoom, specifically. Even the community mouse-follow scripts for OBS assume a mouse. Terminal and IDE demos are mostly typing. ZoomCap treats a burst of typing as a zoom, aims it at where you last clicked (usually the pane you're typing into), holds while you type, and releases when you stop. It doesn't follow the text caret, so click into the pane before you type. If your demos are terminal-heavy, this is the feature that matters.

The editing is mostly done when recording stops. OBS hands you a raw file. Then comes an editor, a timeline, and the twenty minutes that keep you from making the video at all. ZoomCap opens the recording with zooms already placed; you check them, pick a background, and export.

Nothing to configure first. OBS's power is paid for at setup: scenes, sources, audio devices, an encoder you have to have an opinion about. ZoomCap is one command on macOS or Linux, or the browser recorder on any OS, when you just want to record ninety seconds of a feature you shipped.

Finishing in one place. Backgrounds, padding, rounded corners, a macOS window frame, 16:9, 9:16, 1:1 and 4:3 with cursor follow, captions via in-browser Whisper, seven music tracks and style presets, exported as H.264 MP4 up to 4K or GIF. Automatic zoom needs the CLI's click data; on browser recordings or imported OBS files you place zooms by hand.

When OBS fits better

• You're streaming, or need multi-source scenes. A chroma-keyed background, three windows composited into one scene, a capture card, a live stream to two platforms: that's OBS's everyday work, and outside what ZoomCap does.
• You need precise encoder and audio control. Bitrate, keyframe interval, colour space, audio routing per source.
• You're on Windows and want a native desktop recorder. ZoomCap on Windows is the browser recorder with manual zooms.

On recent macOS versions OBS can capture desktop audio through its macOS Screen Capture source; on older setups it needs a virtual audio device, which we cover in recording a Mac screen with audio. The two also work together: record a complicated shot in OBS, then finish it in ZoomCap's editor.

What a finished demo takes in each

Here is the same job, a 90-second feature demo with zooms on the important clicks, done both ways. These are the steps we followed, not estimates from a feature list.

With ZoomCap

1. Run npx zoomcap record in a terminal on macOS or Linux X11. Run npx zoomcap doctor first if you want to check permissions, and npx zoomcap displays to pick a screen.
2. Record the demo. On macOS a ● REC item sits in the menu bar; stop with q in the terminal or ⌃⌥S.
3. The editor opens in your browser with zooms already placed on click clusters and typing bursts. Delete or nudge the ones you don't want.
4. Trim, pick a background and padding, turn on captions (Whisper runs in the browser) and music if you want them.
5. Export an MP4 from 720p up to 4K, or a GIF. It is encoded on your computer.

With OBS

1. Install OBS and run the auto-configuration wizard (choose “optimize just for recording”).
2. Add a display or window capture source, and on macOS grant screen recording permission in System Settings.
3. Check the audio mixer: mic level, desktop audio, and mute anything you don't want.
4. Set the output format and quality in Settings → Output. MKV is safest against crashes; remux to MP4 afterwards from File → Remux Recordings.
5. Record, then stop.
6. Open the file in an editor (DaVinci Resolve, Kdenlive, Shotcut, iMovie or whatever you know), trim the start and end, and cut the dead air.
7. For every moment you want zoomed, add scale and position keyframes in, hold, and out. On a 90-second demo that is often eight to fifteen zooms.
8. Add captions and a background if you want them, then export.

Five steps against eight, and the step that takes longest in the OBS route (keyframing every zoom) is the one ZoomCap does for you.

Cost: free vs $29

ZoomCap Lifetime costs $29 once; Pro at $12.49 a month comes to $450 over three years, so if you know you'll keep using it, Lifetime is the better deal. The free plan gives you the browser recorder and editor with 2 watermarked exports a month, and commercial use is allowed on every plan. OBS costs nothing. The full price box is at the end of this post and on the pricing page.

The money is only half the sum. If a demo takes twenty extra minutes of zooming in an editor and you make two a month, that's about eight hours a year spent on work ZoomCap does for $29 once.

Privacy and safety

Both tools keep your recordings local. ZoomCap records, edits and encodes on your machine: the CLI passes the file to the browser editor over localhost and the video is never uploaded to our servers. The CLI records the timing of key presses to drive typing zoom, never which keys you pressed. Your account is held in Firebase, payments are processed by Dodo Payments, and paid plans come with a 14-day refund if ZoomCap doesn't work for you and we can't fix it (refund terms). The whole data flow is on our security page. OBS writes to your disk and has no account.

When not to use ZoomCap

• You stream, or need scenes, a green screen or several sources in one shot.
• You're on Windows and want automatic zoom in desktop apps.
• You need motion blur or a hosted share link with comments.
• You need system audio on Linux, or you run Wayland: the Linux CLI is X11 and video-only.

A free way to test it

Take a recording you already made in OBS, drop it into ZoomCap's editor on the free plan, and spend five minutes placing zooms, a background and captions. That shows you the finishing half for free. The automatic half (zooms that find your clicks and typing, the redrawn cursor) comes from the ZoomCap CLI, part of Pro and Lifetime, and the 14-day refund applies if it doesn't work for you.
