Problem with MPEG STREAMCLIP

[wildstrawberry]

I have subtitle films that I received on dvd. I am working in FCP

I got the films into fcp by exporting them to quicktime, 100% quality, dvcpro 50 Pal- (the movies are pal)

The QT files have frames missing here and there, so there's a stutter in the video. Happens every minute or so. Any idea what this might be? The original dvds don't stutter.

You don't need DVCPRO 50 PAL, as that means a bitrate of 50 Mbit/s and DVD video is encoded with 7-8 Mbit/s at maximum.

You can use the normal DV PAL codec for a normal edit, which has a bitrate of 25 Mbit/s (3.125 MByte/s).

I don't know where the stutter is from, but maybe your hard drive can't sustain a constant bitrate of 50 Mbit/s (only 6.25 MByte/s), which would be strange. How is the drive connected?

The other thing is, that the MPEG-2 codec used for DVD video uses keyframes, meaning not every frame is compressed, but only ever 25th or 10th frame (depending on the settings I think), and the rest is interpolated.
Maybe it was set to 1500 frames (60 seconds)?

I hope that helps somehow and is not a lot of bollocks (it's already late here).

Agreed, DVCPro is a bit much.

I've never used MPEG Streamclip. I would recommend trying Handbrake.

Do not use handbrake. This will compress to mp4, which is a poor editing format. I am not sure what your issue is. I have had nothing but success using MPEG Streamclip to convert DVDs and VOBs to NTSC-DV and then editing in FCE.
