Our Logitech webcam no longer works properly with Mavericks upgrade. The sound is off, and when recording a video movie with QuickTime player, the video lags then freezes after a few seconds. If you let the recording continue more than 10 seconds, the only Way to quit QuickTime is reboot the computer.
I'm having a similar problem.
The c920 works on my 2011 Mac Mini,
running OS X 10.9.1 Mavericks,
on QuickTime, Photo Booth, FaceTime & Google Hangouts
but only in 720p and the quality looks like 480p.
I purchased WebCam Settings from the App Store
which improved the color & sharpness a little
but it has no resolution settings;
so still no 1080p.
Sound also works,
before & after WebCam Settings
Question: Is it recording in 1080p for you?
Suggestion: Look up Resetting the VRAM by rebooting and holding Command + R + P. I'm probably remembered it wrong, so please look it up before trying it.
Formatted my Drive,
Re-Installed Mavericks,
QuickTime now records in 1080p 🙂
I guess it was an issue with upgrading from Lion to Mavericks?
The fresh install of Mavericks seems to have fixed the issue.
Correction
Either "Get Info" was giving me wrong information on the recorded file's video resolution, or QuickTime is fluctuating it's maximum record quality, because now it's recording supper choppy at 2304x1536.
How the heck do I get the Logitech c920 to record at 1080p 30fps? (''.)
I'd like to know th same thing. I just bought this webcam. So far, it will not record in HD using Mavericks and QuickTimePro 7. What am I doing wrong? In HD the sound starts lagging after a few seconds.
