I am trying to export some clips from a short film to work on in AE. Every time I export as an Animation MOV the only thing showing up in the video is a scrambled upside down blue frame every second or so. I tried h.264 and it just exports a green frame for the whole thing. What is going on??

Need more info.

what are the project settings? hardware on the system?, etc...

1440x1080 24 frames 1.33 PAR
Premiere CS3 3.2
Quicktime 6.5.4
M2T files

Intel Mac 3 gigs of RAM

I can export titles without a problem...and used to export anything I wanted fine. Now no video will export

i just tried selecting 'de-interlace footage' in the export settings and it worked...but why doesn't 'no fields (progressive scan)' work? The footage is all 24f
