What is obs64.exe?

OBS Studio is a free, open-source software for video recording and live streaming. It captures video from sources such as your screen, specific windows, webcams, and graphics overlays, then composes scenes with transitions and audio. It can stream to Twitch, YouTube, Facebook, or custom RTMP endpoints, and runs as obs64.exe on Windows.

OBS Studio's pipeline captures sources, composes scenes, applies filters, and encodes output to streaming or file. It runs on Windows, macOS, and Linux, using software or hardware encoders and a configurable audio mixer.
