I recently bought a Logitech HD Pro Webcam C910 for recording to YouTube, in HD - although 720p would be fine. I wanted to do better than the iSight on my MacBook Pro and 27" LCD display. The camera is superb - under Windows. 720/1080, very good. On OSX - useless. Anything greater than 480 and the image swims horribly. It's just not usable. I've installed it on two Macs, a MacBook Pro (a year or so old) and a MacBook air (last refresh). Same issues. Logitech support are useless. They've suggested removing all video software - and that this is the only way they can suggest it will work. hardly reasonable, and on the MacBook Air, the only video software on it is that which shipped with the Mac itself. Tech support also said I needed to be not running in UVC mode - but provided no advice for how to do this, despite me asking twice. The Logitech software is lame - on the PC you get zoom/pan/tilt and auto follow, lots and lots of options. On the Mac, it's resolution - and er, that's it. There's no setting on either for UVC or not. I would record via VMware, but within seconds the audio and video are out of sync because of them being passed the PC via the Mac. Anyone had any experience of these issues? Help appreciated.
