I'm having a problem I've encountered before CS5, which is that Photoshop is failing to import the first frame of a .mov file. I render a video from After Effects, Animation compression, Best quality. I check it in QuickTime, and all the frames are there. I open it in Photoshop, and the first frame I get is actually the second frame of the file. No way to access the first frame in Photoshop.
I'm not familiar with this issue, but as a workaround until you get a better answer, perhaps just add a frame of black at the head of your MOV ... you could do obviously do that in AE, but since you've rendered already, you could also do it in QT Pro. Hope this helps.
Right, I've been adding a frame in AE at the beginning as a workaround, but this creates other problems as well...it's just annoying that it doesn't work properly! Thanks though, and I'm hoping someone will know what's up with this problem.
