OBS Studio 31.0.0 – Final

OBS Studio (Open Broadcaster) is a free and open source software for video recording and live streaming. It features high-performance real-time video/audio capturing and mixing with unlimited scenes you can switch seamlessly via custom transitions. Filters for video sources are available, including image masking, color correction, chroma/color keying, an intuitive audio mixer with filter functions such as noise gate, noise suppression, and gain can improve the quality.

OBS Studio is equipped with a powerful API, enabling plugins and scripts to provide further customization and functionality specific to your needs. Utilize native plugins for high performance integrations or scripts written with Lua or Python that interface with existing sources. Work with developers in the streaming community to get the features you need with endless possibilities.
