Hi guys. I just got an iSight camera for my DC 2GHz tower. All I can get from it so far is 320x200 recordings (iChat snapshots, Quicktime pro 7 captures). How do I tell it to use 640x480?

I've wondered the same thing. I've never been able to get super-sharp images from mine. (1.25GHz AlBook)

It's still a great camera for video chats, though! It always looks better than the typical PC user's webcam!

Oh yeah, it's beautiful. Figures out exposure in low light settings very well. Audio capture is very reasonable too. I did some VoIP calls with it using Skype and the experience was very good.

Never mind: I figured it out.

In QuickTime, go to Preferences and choose "Recording". Then choose "Device Native" under "Quality". It produces huge files, but at 640x480 that you can then compress later.

This person believes the camera doesn't *really* do 640x480:

Think he's right?

Really? While I totally agree that the iSight has a great set of microphones in it, when I've tried it with Skype, the volume of my voice has been far too low -- I switched to a Logitech USB headset instead. For iChat AV audio or video chats, the iSight mike is perfect, though.

I'm honestly not sure. In 640x480 capture, there are definitely some jaggies, but those could just be the result of a lousy de-bayerizing algorithm. The thing is, whether it's a 640x480 or 320x240 CCD, what is pretty clear is that it's not capturing much (if any) image resolution (as in clarity, not pixel count) beyond 320x240.

I went to system prefs, audio section, and cranked up the recording level. A little past half works great for me. I'm sure it's a much better experience with a headset to cancel out ambient-room noise though. I may do that yet.

Thanks for the QT prefs tip! Awesome! Gave it a whirl and it works great. And yeah, huge files are generated with that setting. It allows for a shorter pause when you begin a recording too as there isn't any pre-buffer for compression to catch up on.

Can someone post a pic taken with iSight? I dropped mine (and dented it) and now my video looks grainy. I don't remember what the picture quality is supposed to be.
