MPEG2 Freezes Vegas 8

[xtremeD63]

Here's what I do:

I rip a DVD in DVDShrink as a single MPEG2 file. Then I open it in Vegas 7, edit as needed and render in a suitable format.

I purchased Vegas 8 Pro and now the MPEG2 files created in DVDShrink freeze it. Vegas 8 locks up now. Anyone know anything about this?

vegas 8 pro imports mpeg2 fine here. as far as i know shrink only makes vobs. you might try using vob2mpeg on them before importing to vegas 8.

[xtremeD63]

It freezes on both. It doesn't freeze on MPEG2 videos not created by DVDShrink, though. This is strange.

Why are you using Shrink ?

Why are you using Shrink ?

my question also --- why?


Vegas will open both program stream mpegs and VOBs just fine

[aedipuss]

vegas 8 opened a file i cut out of a dvd with shrink just fine. must have something to do with your particular dvd.

MPEG2 is a delivery format. It was never meant to be a format that you could edit easily. Especially in Vegas and other editing software.

Rip your DVD with DVD Fab Decrypter. Try it. It can be an ill-formed MPEG2. In this case, try DGIndex, save the project, then use the VFAPI plug-in and open the fake AVI with Vegas Anyway, did you register Vegas 8.0a?

Thank you all for the replies. I found the MPEG2 I was looking for.

New problem, though. The movie I ripped is 23.976 fps. So I edited it like I wanted, and saved it in 23.976 fps, otherwise it looks choppy. When I go to transcode it for DVD burning, the resulting .VOBs look choppy, as if they were rendred in 29.97. I don't know how to fix this. Am I fighting a no-win battle?

Thanks guys.

[aedipuss]

not sure. why are you transcoding it? 23.976 is dvd compliant and will play with the 2:3 pulldown flag. just import it to dlp or other authoring program and make dvd.

[xtremeD63]

It has to transcode before it will burn to the DVD. That's what it's always done.

If you really want to do this, you should invest in the right tools. VideoRedo or Womble are much better as mpeg2 editing than Vegas.

You also need to learn a lot more about digital video if you want decent results.

If you have to re-encode (and if you use Vegas, you will have to), then encode at 23.976 fps with 2:3 pulldown.

How are you authoring at the moment ?

[xtremeD63]

Authoring? As in NeroVision or something like that?

After the MPEG is rendered in Vegas, I play it back in Showtime and it's smooth as silk. No choppiness at all. The problem arises when burning the DVD - the result is jerky video. I looked and looked in NeroVision, and I can't find a way to change the fps to 23.976.

Thanks again.

[guns1inger]

Don't author in NeroVision.

Open the mpeg2 file in g-spot. Look at the number of pics/sec and frms/sec. You should see 23.976 and 29.970 respectively. If you see 23.976 in both, use DGPulldown to add 2:3 pulldown, then author with a decent tool. GUIForDVDAuthor would be a start, although if you are producing mpeg-2 out of Vegas it suggests you also have DVD Archtitect.

Finally, burn with Imgburn so you know nothing else is screwing with the video.

The problem here is Nerovision re-encoding your video to 29.970 fps by adding a lot of duplicate frames, causing the jerky playback.

Thank you guys for all the help. VOB2MPG and VideoRedo were all that was needed. My edited DVD came out just as I had hoped. You guys are the top of the class.
