I have imported a 2sec QT (25fps animation) from AE when I put it into FCP and try and render it FCP gets to about 25% and just stops rendering the clip. I tried it again and it got to the same point then crashed FCP this has happened a number of times after putting these short animations in from AE. If I place an in point on the FCP timeline and export the selected section that works fine.
Footage in FCP was originally HDV 1440x1080 25fps the timeline I'm working in is 1280x720
These settings haven't been a problem at all when the footage is being edited and rendered. It's only when I have exported the 1280x720 square pixel QT animation from AE and put it in the timeline in FCP and try and render that I get these problems.
