mpg from DVD import out of sync

[egproductions]

I copied the VOB files from a DVD and renamed the extention to mpg. Imported the files into premiere and there seems to be a slight out of sync issue over the course of a few mintues. The files play fine out side of premiere (windows media player) but in premiere the audio goes out of sync and there is an occasional random red frame or two.

The footage looks like it was NTSC 29.97 source and of course I import it into premiere the properties say 29.97. I tried interpreting the frame rate to 30FPS and also tried changing the timeline to non drop-frame but the only solution I came up with was stretching the audio. This still doesn't solve my problem with the random red frames though. Is there a reason this happens aside from the fact that mpeg-2s are a presentation format?

I re-built a DVD, but without the problems you describe.

I recently had to do something similar. I'm not an expert, but I've read that simply renaming VOB to mpg can lead to problems, because when footage is taken from something like avi, mov, whatever, it goes through compression and "stuff gets lost" in the process. IOW, and as I understand it, going to mpg is a lossy process.

I used MPEG Streamclip (it's free...do a search) to convert the VOB to avi. Then I imported that to Premiere, inserted it to a new sequence, made my edits, exported the new sequence as .avi, then imported the .avi to Encore. After re-building the menu structure, things were fine. (This way I was able to correct an error from a DVD I authored 2 yrs ago, with no audio problems at all. Of course, now that I've finished all the work, the customer hasn't returned my phone calls, so I may never get paid for this, but I shouldn't be whining here).

Again, I suspect it's that you re-named the VOB rather than converted it, but I'm not sure what's causing the red frames

Others here are much more knowledgeable than me, but I found lots of info on my own. Google a few searches...you'll learn a lot.

Good luck.
