OBS Studio is free and open source software for video recording and live streaming. It features real-time video/audio capture and mixing using multiple sources including window captures, images, text, browser windows, webcams, video capture cards, audio sources etc. You can set up scenes with different combinations of audio and video sources and transition the live output between them. This is pro-AV mixing for free.
The output of OBS Studio can be displayed on a monitor, sent to a streaming service such as YouTube Live or used instead of a webcam for video-conferencing.
This course introduces OBS Studio and how to use it to stream to YouTube Live. Two sessions of 3.5 hours (e.g. 1000 to 1330, 1300 to 1630)
