Macbook Air M1 external webcam

I got a MacBook Air M1 (8 Core GPU, 1 TB, 16GB RAM), and since I got it, I've been having trouble with external cameras (especially in Zoom, but experiencing it all through the machine).


I've tried my Blackmagic Design ATEM mini, Logitech C920 HD, and several apps to use my phone as a web cam.


All of them exhibit dropped frames, freezing, and general slowdowns for the rest of the MacBook Air.


I've also experienced slow downs while streaming video from Wisita (haven't seen any issues with Youtube or Vimeo, but haven't really tried anything there this week).


Any advice or suggestions on this?

MacBook Air 13″, macOS 11.0

I have found a workaround for this. Download OBS 27 from Release OBS Studio 27.0 Release Candidate 2 · obsproject/obs-studio · GitHub, set up a "Video Capture" source that points to your webcam, and then start the "Virtual Camera". Set the camera source to be the Virtual Camera instead of the webcam in your videoconferencing app. The lag is gone, but the CPU usage is up. I am on a Mac Mini M1 so I am not worrying too much about the CPU usage.
