I recently upgraded to a new Macbook Pro with Monterey, and since then Zoom has been giving me problems with the webcam I use for my home office.
I use a Logitech c922 camera with the LogiTune software to crop the camera to focus only on a part of my home office background. However, every time Zoom grabs camera access (including starting a meeting, turning the camera on and off, or even going into video preferences), it treats it as if I am using the default camera settings, ignoring the LogiTune setup.
I can restore the settings by going back to the LogiTune setup process (at which point Zoom recognizes the settings I put in beforehand), but I don't want to be showing my full background for the first 10-15 seconds of each meeting I have.
This is also *only* a Zoom problem -- all other applications that use the camera accept the LogiTune settings without issue. This is also an issue with alternate Logitech software (G Hub) that again works with all other programs.
No fix. Frustrated. Waiting on Zoom to update, but it's a surprisingly long time coming given the popularity of the camera. Had wondered if it was an macOS thing (in case Zoom was forced to implement something Apple gave them) but it seems like every other vendor manages to make the camera work in their software.
Workaround is to open Zoom and start a call, then launch FaceTime or PhotoBooth. These then take over the camera, and the resulting stream (i.e. without the quality problem visible) is also pulled through into Zoom. Going the other way around (i.e. open FaceTime then open Zoom) will degrade the video in FaceTime. Also, remember to open FaceTime once you've actually connected to your call - opening it when you're still on Zoom's video preview screen will fix that video, but won't then apply to the call video itself.
BTW there are references to it being an SD vs HD problem, but it's not - the quality is poor in either mode, and it's much more a "softness" or colour blocking issue (a bit like the 'touch up' option but turned up way too high).
**I am able to control my Logitech c922 camera (to zoom in/out, focus, brightness, contrast, etc) ONLY when I launch and manage the Zoom meeting by using updated Logi Tune software. That was a win and only took me 3 hour chatting with Logitech customer service to figure this workaround out. The old Camera Settings app does nothing.
However, Zoom needs to make an update on their end of things because when I join a Zoom that someone else manages, I have ZERO control over my camera. I will try the suggested FaceTime or PhotoBooth workaround (and post again if it works), but can't imagine that as a long term solution.
I have the same problem on Windows 10 with my 920e. I have to reconfigure my LogiTune settings every time I run Zoom, although changing any one setting will cause all of them to apply.
Oddly Zoom doesn't seem to be using default settings, but something else? For the first 10-15 seconds on every call (before I fix it) my face is completely blown out white and oversaturated. Maybe these were the camera settings that were active when I first installed Zoom?
Google Meet and OBS do not have this problem, only Zoom does.
If you have this problem, maybe try reinstalling Zoom or deleting your user data files wherever they are, maybe you can force it to use new default camera settings.
