OBS Studio

Screen recording and live streaming with scenes, sources and audio mixing

Alternative toCamtasiavMix

OBS Studio records your screen, camera and audio and streams them live, with scenes you switch between and a full audio mixer. It is the open source alternative to paid recording and streaming tools such as Camtasia's recorder and vMix, under GPL-2.0.

Best for when

you record tutorials, courses or screen demos
you stream live to YouTube or Twitch
you want separate audio tracks for voice, system sound and music

Watch out for

it has no editor, so recordings need another program for cutting and zooms
the encoder and bitrate settings are manual, and bad choices show up as dropped frames
on Linux with Wayland, screen capture depends on PipeWire portals and their prompts

Scenes made of sources

Everything in OBS is a scene made of sources: a display capture, a window, a webcam, an image, a browser page, a microphone. You arrange them like layers, add filters such as noise suppression or chroma key, and switch scenes with transitions while recording or streaming to YouTube, Twitch or any RTMP server.

It uses hardware encoders such as NVENC, AMD and Apple's VideoToolbox, so recording does not need to load the CPU. Plugins add features like virtual backgrounds, vertical canvases and advanced audio routing, and the WebSocket API lets other apps and stream decks control it.

What switching really costs

OBS records and streams, it does not edit. Tools like Camtasia bundle a recorder with a simple editor, cursor effects and zoom animations. With OBS you record here and edit in another program, which is one more step if your videos are quick tutorials.

The first setup takes effort: choosing an encoder, bitrate, output format and audio tracks is up to you, and wrong settings give dropped frames or out of sync audio. On Linux, Wayland screen capture goes through PipeWire portals, which works but asks for permission per source.
