Dropped frames in Final Cut Express... what's going on?

Some tudents in the class are having problems with the video dropping frames while playing from the timeline. The video sources play fine and it'll render the movie fine. It only seems to do it on some computers.

Was wondering if anyone else has run into this. I don't know FCE very well, so I haven't a clue where to start for troubleshooting it.

Thanks.

It depends on many factors. How complex is your project? If you have a multi layer with tons of effects and many short clips. FinalCut must acces to many files in a short amount of time. If you are running FinalCut from a laptop, the drives are slower and thus more prone to droping frames. Usually before an output. I will export my project to a Quicktime movie in the same settings as my project. I will the re-import it and output it to tape. That way FinalCut only has a single clip to read and has a lot less chances to drop frame. I also backup this Quicktime file to a DVD-R. That way, I have a backup of my project in case my tape is damaged.

They're eMacs and the projects are fairly simple. I guess I'll have to do some investigation cuz it only does it on some of the computers. Though, technically, they're identical. It's really weird.

It can also be caused by disk fragmentation. It could be a logical explaination. Even if the computers are similar the disks have diferent degree of fragmentation.

The first place I would look is at the Remaining Hard Drive space on the drive that holds the video. If the disk is more than about 70% full you will start to notice things like this. The fuller a disk gets teh slower the seek times become to find information. If you have a 80gig Hard Drive I wouldn't let it get below 20 gigs free.

Not that things won't work just thats where you start to get problems.
