.mov is playing without video in final cut
I'm working on FinalCut 7 and when I bring a folder of broll from the capture scratch to the project, the .mov files suddenly won't play video. I can hear audio but the screen in my viewer is white. This change also occurs in the capture scratch once the files are moved to the project; it just plays audio. How can I troubleshoot this?
