Thank you Jeff,
I am going from NTSC DV 720 x 786 compressed (tested with both the preset and my own settings) to Mpeg2. It is strange, I don’t see it in the original quicktime, when I play back the source (before compressed) in QT and in FCP. It’s not on other mpeg files that were generated a year ago from the same source, so I’m trying to figure out what the problem could be. It does look like an over scan, but it also looks like there is a frame misregister with the image, taking white lines from the bottom of the frame and putting it on top.
It doesn’t happen all the time, only on some clips.
thanks,
Lili
