      I captured the footage on Screenium 2.1 at fullscreen on my MacBook Pro (1280 x 800) and edited together several days worth in Screenium. I then exported it as a .mov, it is 11.31 Gb. I created a custom composition in AE measuring 1280 x 720 with 24fps. I can import and place my footage into my composition fine, but as soon as I try resizing or moving the footage within my composition I get the above error message. I have tried creating compositions with the same frame rate and other frame rates (8, 12), I've also tried interpreting the footage and conforming the frame rate to 24 (even though it is already on 24), before placing it into my composition but none of that has worked. The error message stays even after clicking 'OK' and I eventually have to Force Quit the program.
