I would like to 'overlay' two individual video feeds from two i-phones (with individual audio feeds from each person via XLR cable) to an existing video so as to stream both the prerecorded video as well as the live video simultaneously.
Meaning: I would first create a 'zoom-like' video with 2 'missing' squares. When going live, I want to fill in the missing squares with the live video (and audio) from our i-phones.
Any suggestions? Many thanks in advance!
