What Is OBS Studio and What Can You Do With It?

Updated

OBS Studio is free and open-source software for video recording and live streaming, available for Windows, macOS, and Linux. It fits anyone who needs to capture and mix real-time video and audio — streamers sending to Twitch or YouTube, people recording locally in H.264/AAC, or anyone building multi-source productions with scenes, transitions, and an audio mixer. If you only need a one-click screen grab with no mixing or scene switching, OBS is more tool than you need; if you want control over sources, audio, and layout, it's built for exactly that.

What OBS Studio actually does

At its core, OBS captures and mixes video and audio in real time, then sends the result either to a streaming platform or to a local recording file. The official feature set describes it as:

  • High performance real-time video/audio capturing and mixing
  • Scenes made up of multiple sources — window captures, images, text, browser windows, webcams, capture cards, and more
  • Unlimited scenes you can switch between seamlessly via custom transitions
  • An intuitive audio mixer with per-source filters such as noise gate, noise suppression, and gain, plus VST plugin support
  • H.264 / AAC encoding for high-quality output

That combination — sources, scenes, and a per-source audio chain — is what separates OBS from a plain screen recorder.

Key capabilities, grouped by what you're trying to do

Capture and compose a scene

A scene is a layout you build from sources. You can add window captures, images, text, browser windows, webcams, and capture cards, then arrange and adjust their properties. You can create an unlimited number of scenes and switch between them with custom transitions, including stinger video files.

Control your audio

The built-in mixer works per source, so you can apply filters like noise gate, noise suppression, and gain to individual inputs rather than the whole mix. VST plugin support extends this further if you need more advanced processing.

Stream or record

OBS supports "all your favorite streaming platforms and more," including Twitch and YouTube, and can also record your own videos locally. The same scene setup serves both — you choose whether the output goes to a platform or a file.

Run a more advanced production

  • Studio Mode lets you preview scenes and sources before pushing them live, so you can adjust or create new ones and confirm they're right before viewers see them.
  • Multiview gives a high-level view of your production — monitor 8 different scenes and cue or transition to any of them with a single or double click.
  • Hotkeys can be set for nearly every action: switching scenes, starting/stopping streams or recordings, muting audio sources, push to talk, and more.
  • A powerful API enables plugins and scripts for further customization, with native plugins for high-performance integrations.

Arrange the interface your way

The modular Dock UI lets you rearrange the layout as you like, and you can pop out each individual Dock into its own window. The Settings panel is a single streamlined place to configure every aspect of your broadcast or recording.

Platform and version requirements

Platform Requirement
Windows Windows 10 and Windows 11
macOS macOS 12.0 or newer (Intel and Apple Silicon builds available)
Linux Available (version selection listed on the download page)

The latest release listed is 32.2.2 (August 14th). The project is funded through sponsors and backers.

How to decide if it fits you

OBS is a good fit if you:

  • Want to stream to Twitch, YouTube, or other platforms from Windows, Mac, or Linux
  • Need to mix multiple video and audio sources into one output
  • Want scene switching, transitions, and preview-before-live control
  • Want per-source audio filters and VST support
  • Want to extend functionality with plugins or scripts

Look elsewhere if you:

  • Only need a simple, single-source screen recording with no mixing
  • Don't want to configure sources, scenes, or encoding settings

Getting started

  1. Go to the OBS download page and pick the build for your OS — Windows 10/11, macOS 12.0+ (Intel or Apple Silicon), or Linux.
  2. Install and launch OBS Studio.
  3. Add sources to a scene (window capture, webcam, image, text, browser, capture card, etc.).
  4. Check levels in the audio mixer and apply per-source filters as needed.
  5. Choose your output: configure a streaming platform or set up local recording.
  6. Optionally enable Studio Mode to preview before going live, and set hotkeys for the actions you use most.
