Despite the fact the videos are from the same source, there is obviously something different between the ones that work and those that don't. When I encounter this problem, I experiment with converting the problem clips to another format, using one or more of the following:
- Quicktime 7 Pro
- FLV Crunch (despite its name, it does more than FLV)
- MPEG Streamclip
I usually try converting them to .MOV (Quicktime) format, however sometimes using FLV Crunch to convert the clip to its same format fixes the issue - I have no idea why.
There's also an option when importing files - when you import them using a menu and not with drag-and-drop, that specifies whether the video should be optimized during import or not. Turning this on or off can sometimes make a difference, but be aware that this option can affect quality.
Trial and error is the key. Just remember to keep your original files until you're sure you've found the right solution.
