Hi, and thank you for your reply.

Frame-by-frame image-exports are fine, but video doesn't work properly above 12 fps, as I've learned. I ended up exporting the movie as DV-pal, which worked at a very good quality, but changed the aspect ration. I then fixed that in Quicktime, and got a nice quality video that even got the HQ-button on Youtube - http://www.youtube.com/watch?v=nwkbZPpPsMk
