Today I was using zoom.us cloud meeting software for my community engagement, but also streaming directly from the ATEM. This was a mobile battery powered livestream, so using the ATEM as my video source was really effective. The problem is that the audio and video signals loop back into the meeting software. If it were possible to pin the UVC output to a single A/V input that would solve this problem entirely. So I’m going to post it on the Blackmagic forum.
Using zoom.us my audio pathways look like this:
Microphone -> camera -> ATEM -> UVC audio+video -> Zoom
The cheap fix is to introduce an XLR audio interface in between the mic and the ATEM:
Microphone -> Audio Interface -> Zoom
Audio Interface -line level-> Camera -> ATEM -> UVC video only -> Zoom
I also now have a backup ATEM Mini, and considering the price it’s a shame that I would use it to replace a $100 part like the Zoom microphones U-22.
That dual-ATEM setup will look like this:
Microphone -> Camera -> ATEM A -> Monitor Out -> ATEM B -> Stream
ATEM A -> UVC audio+video -> Zoom
Because my PC’s audio output is currently lost in the mix I need to go back to the drawing board. Genuinely, creating hardware audio busses with few wires is a tricky puzzle and I’m thankful for the practices I’ve learned from vMix and Voicemeeter that will help me figure this out in the next few days.
