User interface

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. The layout of the interface can further be customized by undocking or adjusting the size and location of each panel. 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".

History

OBS Studio started out as a small project created by Lain Bailey, but quickly grew with the help of many online collaborators working both to improve OBS and to share knowledge about the program. The first version was released in August 2012. 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. In 2016, OBS "Classic" lost support and OBS Studio became the primary version. In March 2022, OBS was released on Steam for both Windows and Mac. On 16 December 2021, an OBS Studio developer drew attention to an invitation-only release of
