Importing from DVD - multiple frame rates

SteveC100 Aug 12, 2013 11:55 AM

I'm working on an editing sample reel, using material from DVDs. I rip the DVDs via either Ripit or Mac DVD Ripper Pro (MDRP) and then import either the whole disk or the individual vob files into Premiere Pro CC. Either way, the first clip of the main feature displays a frame rate of 29.97 in PP, while the other vobs from the main movie display 23.976. 29.97 is clearly wrong -- video shows a lot of tearing, when you stop you see frame jumps, and sync drifts. All the 23.976 files look good. I've opened 7 DVDs this way and all have the same problem -- the first file is wrong, the others are right. (Image below -- first file is at 29.97, the others are at 23.976.)

If I change the frame rate on the first file, it looks better but it's running too slow and audio sounds s l o w e d down.

Anybody know what's going on here? I was excited to use Premiere for this project, because it can work with the DVD files without transcoding. But so far, no love.

Thanks,

Steve

I've now looked at the vob files with vlc and they all appear to be the same -- all stamped with 59.94 as a frame rate.

So I'm mystified by this. Have ripped more DVDs now, some come in correct, some don't.

If I use handbrake and convert each chapter separately, I can get them all to play properly at 23.976

So maybe this is a bug in the way Adobe interprets the frame rate of the vob file.

You might Read Bill Hunt on editing a VOB/MPG file http://forums.adobe.com/thread/464549

Some VOB files contain a LOT of information besides actual video... which may be your problem

Thanks, John. I read that earlier today but there's not much specific to my situation.

But there's clearly something different about that first vob file that's confusing PP. Too bad -- because otherwise, PP is well and away the slickest way to handle this stuff.
