Yep they are, as each clip needs to continue to play for the full 30 second spot, so I think you're right I'm going to have to move the project to Ae and do some precomps. Premiere started doing some weird stuff with my video clips (After pre-render it would invert the image and shift them all to black and white) which I couldn't find a fix for, so its back to the drawing board as far as prepping them goes.
I think Ann is right, too. The client supplied all the clips, (1280x720 MTS, 60fps) some of which are an hour long, but I only need 30 seconds or less of each clip so it could also be a conforming issue, as a lot of these files are HUGE. I was hoping my machine could handle it (ASUS G73JH, intel 8-Core i7, ATI HD5870, 12 Gigs RAM, 2TB external swap drive/storage, 1TB Internal HD, 512MB SSD Internal swap drive) just because I'm basically lazy and didn't want to have to pre-render each clip, but now it looks like I'm going to have to. I was hoping there was some new sneaky way of only importing select edits of video clips with CS6, but it looks like its manual edit/export for all 50 of 'em.
Good thing I was paid in advance
