I'm using FCP 7. Recently, it has developed an issue with clips that have had speed changes applied. If I speed up or slow down a clip, that portion of the final product (generally a .mov) won't play or isn't there after export. Has anyone ever encountered this problem before? Any advice.
When you say "generally a . mov" you're implying that you have other clips in the sequence that are not QuickTime files. What are they? Hopefully not mp4 files. And, what is the codec of the .mov files (QuickTime files)?
