What changed with the latest Zoom Mac update regarding connecting Camcorders?

Hi All,

First off, I don't find a post "Location" that makes sense for this post out of the choices available.  I think there's an assumption that everyone is familiar with the myriad services Zoom provides, and I just use Zoom for meetings, thus the location choice, "Meetings".  That's the most general choice, as the others are so specific yet unrelated to my post.  I don't see any location regarding hardware issues or webcam issues.  If someone can tell me where to better post this, I'd appreciate it.

Now, the reason I'm posting.  A few weeks ago and for months before that, I was able to successfully connect my camcorder to my MacBook Air via an HDMI cable from the camera into a small, cheap HDMI-to-USB adaptor, which was then plugged into the USB port on the MacBook.  I could choose "USB Video" or something like that as the camera on Zoom, and the video from the camcorder became my webcam for Zoom calls.

However, since installing the latest Zoom updates, I can no longer get video signal in the above set up to work on Zoom.  All I see is color bars when I choose "USB video" or "USB Camera" as Camera on Zoom Video Settings.  Frustrating.

Was this intentional on Zoom's part to disable USB connectivity with HDMI camcorders?  If not, will this be fixed?  If not, what is required with the new update to use a camcorder as a USB connected webcam, please?

Many thanks,

Tim
