MPEG from a DVD

Vegas 7 and MPEGs imported from a DVD.

Is there a good reason why they won't play well, even at Preview quality?

Doing nothing but cuts-only, but I can't even get that far. It takes a good 5 minutes to even show the frame the cursor is on. (it does the 1345. 1345.. 1345... thing.)

1 GB of ram, plenty of room on the defragged hard drives (separate ones for video, OS, and pagefile)
 
I too have found mpg and wmv format to perform poorly on the timeline. The render will be fine, but I've found editing to work just as you describe. If I have a lot of edits to do, I will first render to uncompressed AVI and then use that to do all my edits.
 
David: not from the DVD. Used the Import Media thing. Does that convert the .VOBs to something weird? They got dropped into the Project as MPEG-2, 29.97 fps. (Guess the DVD wasn't progressive.)

Mark: I was thinking about doing that, but this "project" is just for fun/editing practice and that's whole lot of time and HD space. :(

Also tried it with v6. Same.

Odd thing is I've edited DVD footage before without much trouble. Although the other footage was from a DVD-Cam, not a "real" DVD.

Importing it only creates the reference in the Media Pool; it doesn't copy the data. If you didn't transfer your .vob files to hard drive, then you're editing from the DVD, and that's exactly the kind of behavior I'd expect from such a slow drive.
 
Um....then it should be a lot slower than that. The DVD is sitting on the shelf in the livingroom.

The are .mpg files. They play fine in WMP, too. But on the timeline...fuhgeddaboutit.
 
AH. I misspoke. Import | DVD Camcorder Disc

Which I'm assuming isn't supposed to work for "real" DVDs. (Although it didn't object to it at all)
 
I've never had a DVD camcorder, so I've never tried it.

Try simply lifting the .vob files off the disc and into your hard drive.
 
Nope. Same problem. (Except now there are 4 1 gb files instead of a bunch of much smaller ones. Looks like the Import does scene detection.)

Additional symptoms: Audio plays fine, even though the video just sits there.
 
If they are commercial movie dvds this is bound to happen. Plain mpeg2 files will work ok. Maybe from your dvd camcorder. Since the files on those camcorders are purely mpeg2. But a commercial hollywood dvd is a totally different story. They employ a lot of content scrambling techniques so the damn thing will never play well on the timeline. Also when you lift a .vob off a commercial dvd it invariably has a 5.1 soundtrack attached to it which you cannot eliminate since is weaved into the vob. 5.1 sound import doesnt work in Vegas. Only 5.1 export. This will cause the incoming movie to skip and be out of sync. It will miss an entire bunch of frames etc. Whereas try a noncopyrighted dvd and that mpeg will never skip and stutter on your timeline. An import from your camcorder disk is non copyprotected and those mpeg streams should work ok on your system. If you have a ripper tool which can rip from the hollywood dvd right into avi with a codec of your choice. That should be your safest bet. Try it out.

Yeah, I was thinking of running it through DVDShrink (without actually "shrinking" it) or Nero Recode to see if that would make it work better.

Not sure it is worth the effort. Doubtful the filmmakers would appreciate it, anyway. Then again, the film is in desperate need of it. :)
