Ok...I feel like I'm going insane trying to figure out just what is going on with some of the video files I'm previewing in both Premiere and Virtualdubmod. Here is what happens:
I'll preview a clip from an mkv file (loaded w/ directshowsource in avisynth). When the file plays in the monitor in Premiere (after a bit of stutter most likely due to a not-so-super computer), things seem fine. But when I slow it down and go frame by frame, looking for the right part of the clip I wish to use, the video starts stuttering around, with frames out of sequence. It all seems rather random, but what usually happens is a frame anywhere from .5s to several minutes finds its way in between the frames I'm slowly going through. Nothing else happens really, just frames appearing where they shouldn't be. I then try hitting "play" instead of going frame-by-frame, and now it no longer appears smooth, but those random frames start jumping in.
I figured this was some kind of FPS problem (the mkv file was 23.970, and I used assumefps(24)), so I took off that line in the avs file, but no luck. (By the way, I had Premiere set for 24 fps). So I tried letting premiere handle the fps conversion, and set it to 24fps, but that did not help either. I also tried exporting it, but the problem still exists (I used huffyuv2.1.1 in project settings, and exported as avi). The codec of the original mkv was h.264, could that be an issue?
So I'm beginning to this this is a premiere issue. So I look at the mkv (using avs once again) in virtualdubmod, and the problem exists there as well. And its just as weird. The file plays fine the first time through, but when I go back and then forward frame-by-frame, it gets weird. Then when I play at normal speed once again, the jumping around still occurs.
Oh, and just for the record, this only seems to not occur with .vob files (I also tried making that mkv an avi file, thinking it was just premiere not liking mkv's, but no luck). I've tried to duplicate the issue with .vob files, but cannot.
Anyone have any ideas?
Thank you ahead of time.
