I am experiencing crashing with FCP 7, I have a 60 minute HD show and have some clips that are mp4. I understand these clips are hard on FCP 7 and may be the cause of the crashes. Also, even though I render the entire project, when it crashes and I re-open the project, many of the clips need to be re-rendered again. Very frustrating. ANy ideas why? Thanks.
