My project plays for a few seconds and then suddenly stops. I have to hit the space bar again to get it to start up again, but it doesn't go for long before it stops again. The same happens whether it's on automatic quality or highest quality. I have rendered the full movie, so that's not the problem.
The project is only 13 minutes long. Is it possible that the .mov file has some wrong settings? I've been having problems capturing video straight into Premiere Pro (problems with audio), so I've had to capture into iMovie, then "share" it with expert settings into a .mov file. However, I may have some of those "expert" settings wrong (since I'm not an expert).
I appreciate any suggestions you might have.
