OpenScreen vs OBS Studio

OpenScreen and OBS Studio are both free, open-source screen recorders for Windows, macOS and Linux, so choosing between them is mostly a question of editing. OBS records and streams scenes built from many sources and leaves editing to another app, while OpenScreen records a display or one window and edits the take itself: automatic zooms, a cursor you restyle afterward, on-device captions, and MP4 or GIF export. OBS Studio is still the better choice for live streaming and multi-scene productions.

This page is published by the OpenScreen project. The OBS Studio details come from obsproject.com, the OBS Studio GitHub repository and Flathub, and were checked in September 2026. The sources are listed at the end.

What both tools do​

The two overlap more than the "streamer versus editor" split suggests. None of the following is unique to either.

  • Free and open source. Both cost nothing, and both publish their code on GitHub. Both licenses let you use the app for paid work.
  • Windows, macOS and Linux. Both ship for all three, with macOS 13 as the minimum.
  • Screen, webcam, microphone and system audio in the same recording.
  • Recordings that survive a crash. OBS's default Hybrid MP4 and MOV formats stay recoverable if writing stops. OpenScreen writes fragmented MP4 on Windows and macOS, so a take cut short stays readable up to its last second or so.
  • Local speech-to-text with Whisper. OpenScreen has it built in. On OBS, the LocalVocal plugin runs Whisper on your machine and can show live captions through a text source.
  • Automation. OBS includes a WebSocket server for remote control and runs Lua or Python scripts. OpenScreen has a command line that records, exports, captions and packs projects, with JSON output.

Where OpenScreen differs​

Editing in the same app​

  • A timeline after the take. Import recordings or existing videos, reorder them, and set in and out points and a crop for each clip. Cut spans, and change speed from 0.1× up to 100×. See Editing & timeline and Media library.
  • Zooms placed afterward. Auto-enhance → Automatic zooms reads the recorded cursor movement and drops zoom regions where the cursor dwells, with no network call and no model. Manual zooms at six depths sit alongside them. The OBS "Zoom to Mouse" script zooms a display capture when you press its hotkey, so each zoom is decided during the take. More on auto-zoom.
  • A cursor you can change afterward. By default, OpenScreen records the pointer as data rather than pixels. You can resize it, smooth its path, and add motion blur and a click bounce after recording. What each system captures is listed under Cursor mode.
  • Framing. Add a wallpaper, a solid color, a gradient or your own image behind the recording, with padding, rounded corners and a shadow. Output as 16:9, 9:16, 1:1, 4:3, 4:5, 16:10, 10:16, or the clips' own shape.
  • Annotations on the timeline. Text with six animations, arrows in eight directions, images, and blur regions, Gaussian or mosaic. OBS adds text and images as scene sources while you record. OpenScreen places them after the take, where you can move them.

Captions and transcript​

  • Captions without a plugin, on all three systems. whisper.cpp ships inside the app. One Whisper Small model of about 264 MB is downloaded once, and captions are burned into the video. OBS's own captions tool is built only for Windows. More on captions.
  • Editing by text. Select words in the transcript and delete them to cut that passage from the video. Silences are marked and can be cut the same way. See Transcript editing.
  • Caption translation into 15 languages, through an AI provider you connect.

Export and chat editing​

  • An export step with choices. MP4 at 720p, 1080p or source size, at 24, 30 or 60 fps, in H.264 or H.265, or a GIF. No watermark. In OBS, the output resolution, frame rate and encoder are set in Settings before you record. See Export.
  • Optional chat editing with your own key. Describe cuts, zooms, speed changes or annotations in plain language. Each change lands as an ordinary undoable edit. It is off until you connect a provider. See AI editing.

When OBS Studio is the better choice​

  • You stream. OBS streams to built-in services or to a custom server. OpenScreen records and edits.
  • You produce with several sources. OBS offers unlimited scenes, custom transitions, a Studio Mode to preview changes before they go out, and a Multiview that monitors 8 scenes.
  • You need a caption file. The LocalVocal plugin writes .srt files. OpenScreen burns captions into the video.
  • You run Windows on ARM. OBS publishes a Windows ARM64 zip (as of September 2026). OpenScreen's Windows builds are x64.

Using both​

You do not have to choose. OBS can record, and OpenScreen can edit the result.

  1. Record in OBS. Since version 32.0, new profiles record to Hybrid MP4 on Windows and Linux, and to Hybrid MOV on macOS.
  2. In OpenScreen, switch to Media and choose Import media. The file dialog accepts mp4, mov, mkv, flv and ts files, among others.
  3. Drag the source card onto the clip row, then cut, speed up, zoom, annotate and frame it as usual.
  4. Select its card in Media mode and choose Regenerate to transcribe it for captions and transcript editing.

Some features will not apply to an OBS file. Automatic zooms, cursor-following zoom focus and cursor styling read the cursor data that OpenScreen saves next to its own recordings, and an OBS file has none. Manual zooms still work. If your OBS scene included a webcam, the webcam is part of the picture, so OpenScreen's webcam layouts and Full Camera segments have nothing to work with.

Getting started​

  1. Download OpenScreen from the download page. On Windows, the Microsoft Store is the recommended route.
  2. Follow Installation. On macOS, grant the Screen Recording and Accessibility permissions before the first take.
  3. Make a first recording with the quick start, then run Auto-enhance → Automatic zooms on it. To edit an OBS recording instead, start from Media library and add captions.
