Same issue with Logitech C925e, only after upgrading to Monterey. I have three C925e cameras I have experienced the same issue with, all tested against the same computer with multiple versions of Zoom. It does not appears to be a USB 2.0 or hub issue, since I experience the same issue when connected to a hub or directly connected to the laptop.
The video is very blurry whenever Zoom initiates the camera, constantly struggling to maintain focus. If you open any other application that properly uses the webcam AFTER starting your video on zoom, it fixes it (LogiTune, Facetime, Photobooth, etc.). Even if you have the other application open when you start Zoom, turning the camera on in Zoom causes the video to return to its faulty and unfocused state. Issue does not occur in Google Meet, Microsoft Teams, Slack, etc.
Well, it’s been months and nothing has changed. I don’t know if Zoom sees this? We’ve had zoom updates ever since Monterey but other than that is there anyway that we can pass this along to them? Can we at least have an assurance that this will be fixed?
This thread only has 9 upvotes but 51 replies? How many of us have filed bug reports and/or contacted Zoom directly? I suspect that the only way to hope for action on this issue will be for most/all of us to waste a lot of our time bugging Zoom about it. I doubt they actively read these threads...
I have had lots of back and forth with Zoom support but no solution. My problem was that when using MacBook Air and Logitech camera, the videos was marred by frequent flashes but only when I checked the HD box. So I simply unchecked that and no recurrence. Zoom suggested I log onto the Zoom website and check "Group HD" in settings. I did. I don't think I get HD quality that way though. I don't have this problem when using an HP Windows machine and the Logitech camera.
Here's the content of my most recent support ticket... feel free to copy it and file your own ticket:
Hello,
There are numerous reports in of poor video quality with Logitech cameras using recent Zoom versions (including v5.9.1) on macOS Monterey 12.x.x.
The issue has been narrowed down to be a Zoom-specific issue by multiple people, who have all confirmed that their cameras work correctly in all other (non-Zoom) apps.
Cameras that are known to be affected by this bug are: Logitech C920, C922, C925, C925e. You can find details about other people this bug is affecting in these threads:
One workaround to temporarily correct the poor video quality is to open another app that uses the camera (e.g. Logitune, facetime, photobooth) while Zoom is also using it. Doing this somehow forces the camera back into it's correct high-definition mode for the duration of the Zoom call. Once the camera is turned off, the process has to be repeated again next time Zoom is used.
Although multiple people have succeeded in using the workaround mentioned above, it is a hack and an inconvenience to Zoom users. Please provide an update on if/when Zoom intends to address and properly fix this issue.
I've been in contact with Zoom support too, and they said they're aware of it, but that was two months ago. I have no idea why they wont fix this. Must be affecting thousands of users by now, these cameras are really common.
