OBS Studio (formerly Open Broadcaster Software or OBS, for short)[9] is a free, open-source, and cross-platform screencasting and streaming app. It is available for Windows, macOS, Linux distributions,[a] and BSD.[b] OBS Project raises funds on Open Collective and Patreon.[10][11]


OBS Studio is a free and open-source app for screencasting and live streaming. Written in C/C++ and built with Qt, OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via the Real Time Messaging Protocol (RTMP). It can stream videos to any RTMP-supporting destination, including YouTube, Twitch, Instagram and Facebook.[12]

For video encoding, OBS Studio can use the x264 transcoder,[13] Intel Quick Sync Video, Nvidia NVENC and the AMD Video Coding Engine to encode video streams into the H.264/MPEG-4 AVC or H.265/HEVC formats.[14] It can encode multiple tracks of audio in the AAC format. More experienced users can choose any codecs and containers available in libavcodec and libavformat, or output the stream to a custom FFmpeg URL.[15]

OBS Studio also supports plug-ins to extend its functionality.[16]

User interface[edit]

OBS 24.0.0

The main user interface is organized into five sections: scenes, sources, audio mixer, transitions, and controls. Scenes are groups of sources like live and recorded video, text and audio. The mixer panel lets the user mute the audio, and adjust the volume through virtual faders, and apply effects by pressing the cogwheel next to the mute button. The control panel has options for starting/stopping a stream or recording, a button to transform OBS to a more professional Studio Mode (see below), a button for opening the settings menu and a button to exit the program. The upper section has a live video preview, used to monitor and edit the current scene. The user interface can be switched to a variety of themes, including both dark and light themes, depending on what the user prefers.

When in Studio Mode, there are two canvas preview windows, the left one for modifying and preview of non-active scenes, while the right window is for preview of the live scene ("Preview" and "Program" respectively). In the middle there is a secondary transition button, allowing for transitioning to the non-active scene in the left window using user-defined "quick transitions".

There are some simple tutorials on the Internet that show how to use OBS Studio,[17][18][19] including more in-depth tutorials designed to cover every aspect of the application.[20]


OBS Studio started out as a small project created by Hugh "Jim" Bailey, but quickly grew with the help of many online collaborators working both to improve OBS and spread the knowledge about the program. The first version was released in August 2012.[21] In 2013, development started on a rewritten version known as OBS Multiplatform (later renamed OBS Studio) for multi-platform support, a more thorough feature set, and a more powerful API.[22] In 2016, OBS "Classic" was no longer supported, and OBS Studio became the primary version.[23]

Usage in other software[edit]

Streamlabs Desktop (formerly Streamlabs OBS)[24] is a live streaming app that integrates OBS Studio with viewer interactions, chat management, and tip donations.[25][26] The app uses OBS Studio for media streaming and Electron for its user interface.[27] It distributes contents over Twitch, YouTube Live, and Facebook Live.[28][29] The first version of the app was launched on 31 March 2020 for macOS.[30][31] On 18 November 2021, following criticism, the app's name changed to Streamlabs Desktop to prevent any illusion of affiliation with OBS Studio.[32][24]

On 16 December 2021, an OBS Studio developer drew attention to an invite-only release of TikTok Live Studio, which appeared to be based on OBS Studio, without acknowledgement and in violation of OBS Studio's license.[33][34]
