I have been working on this video project for the past week on FCP and I have been filming/ receiving footage from a variety of cameras, which was a problem but I thought I fixed it. Anyway I finished my project and exported it and it seems to me like some of the files may be corrupt? They start out fine but then either change to a gray or green color. The audio still works fine and in FCP on the timeline everything worked fine so I have no idea why this is happening?? Help as soon as possible would be nice, thank you!!
