I did a search on this, but couldn't come up with anything... I'm using the Quicktime 2K proxies in After Effects CS3 and every once in a while, when doing a RAM preview, I get frames in my footage that drop about 20IRE. I've found changing the Project Settings to 32 bits seems to snap the footage out of it - but, every once in a while the dark frames still pop up.
Anyone else have these experiences? I'm running OS 10.5.2 and Quicktime 7.4.1
