OBS stands for “Open Broadcaster Software”, and the Studio product is an open-source, free platform for video streaming and recording. It creates a virtual webcam for just about any platform, including Zoom, Google Meet, and MS Teams. It supports multiple cameras, overlays, virtual backgrounds (chromakey), and much more. It is a sophisticated system with a bit of a learning curve, but it’s infinitely extensible through a long list of add-ins. Available for Windows, iOS, and Linux.
