One Possible Reason for Jerky Video Output

[bdaniel]

I have a 12.2G DV video that I dropped onto the time line as one clip and then did Clip -> Save Trimmed Video.

I spot checked the output using Windows Media Player and found a few places with jerky video. I exited and re-entered the Media Player several times and the video was always jerky at the same place. The original was OK.

The original was on my E: drive and the clip was saved on my C: drive. I decided that maybe the file was fragmented because I have not defragmented my C: drive in months or more. So I simply copied the saved clip file onto my D: drive. I tried it again and everything played fine. So I think the problem was a hard drive that needs to be defragmented. Horsepower is not a problem because I have an AMD dual core 3800+ and 1 GB of RAM.

Also I wanted to compare the two file sizes. I made no changes
Original: 13,194,172.417 bytes
Saved : 13,159,959,684 bytes

The saved clip is about 35meg shorter. Any ideas why? I want to break up some of my long DV files into shorter clips and save them as separate files with no loss in quality.

Thanks,
Bobby
