Ok, I got two more iSight cameras, and something's happening that I
don't understand.
With two cameras installed, I put two video input patches in my
composition. The first one shows me a 640x480 image. The second one
produces a 176x144 image. It's rather jarring visually for one to
have so much less resolution.
My system is a dual 2.0Ghz G5, with a GeForce 6800 Ultra, 256MB VRAM,
driving a 30" Cinema display. I have both of the cameras plugged
into the FW ports on the display. With three cameras, the third input
patch gives me an even smaller image.
I've looked at the device settings for both of the input patches, and
they're identical. How do I get them both to hand me a 640x480
image, or failing that, get them both to the same size?
Am I running out of FW bandwidth? Do I need to pick up a FW800 hub,
and plug the cameras into that, or do I need to upgrade my machine
and video card?
The input patches all defaulted to using CCIR-601-uyvy compression,
and there are a LOT of other choices. Would any of them help?
Thanks,
