i made a screen video with quick time 10, definition is 1280 x 800, i am trying to import in final cut, but i got error, i am not allowed to import it in,
with video at 640 x 480 everything is ok, how can i overide this problem ?

I'm not familiar with FC, but it's probably the frame size that's giving you problems.

FC is probably expecting 1280x720. What are your project settings?
