DVD and VOB file

CAPVideo wrote on 8/15/2007, 5:54 PM

If I know that the AVI will fit on a 4.7gb DVD, does DVDA absolutely have to render it to an MPEG2 before converting it to a VOB file. I know that Pinnacle Movie Studio Plus (version 11) gives you the option of building the DVD without converting to an MPEG2. It just converts the AVI to a VOB.

A VOB file IS an MPEG2 file. No matter what route you take, your video will be MPEG2 by the time it is burned to a DVD. Movie Studio Plus was converting the AVI file to MPEG2 when creating the VOB file. Any software you have used has done this, whether it was obvious about it or not.

Thanks for the reply. The quality is extremely high which makes it hard to believe that it is an MPEG2. Maybe it is rendered at a high fixed bit rate. What do you think?

Could be rather high. DV is about 25mbps for the video. You said the AVI file would fit on a 4.7GB disc, so the movie must be pretty short, probably under 21 minutes. An MPEG2 file that length could fit all the way up to ... 25mbps. The practical limit for DVD player compatability is about 9mbps though.

CAPVideo, Cienworks is correct Pinnacle Studio Plus (no "Movie" in the name) converts the AVI file to MPEG2 in the MakeMovie process.

It confused me a little at first as well when I migrated from Pinnacle Studio to VMS. VMS and DVDAS are separate applications whereas Pinnacle combines editing and disc authoring in the same application.

In my opinion, the way Sony does it is far superior and stable. After getting VMS/DVDAS, I vowed never to use Pinnacle for disc authoring even if I may use Studio for *some* situations. DVDAS is much more flexible and gives you more options.

Couldn't agree more that Sony has got the better product. I have been a Vegas user for years. We rendered a DVD using Pinnacle 11 and there is a setting that states you can render to DVD = Native DVD which does not seem to add any compression. Any notes on this you may have would be appreciated.

ps. I realized that I posted this in the wrong forum. Is there a way to move the message to DVD Architect forum?

Thanks

I didn't upgrade to S11 so I'm not familiar with that setting. You may need to go to the Pinnacle forum to ask.

Regardless though, while it may not ADD compression, it will render it to an mpeg file just as DVDAS would. It's all about the bitrate used to make the file fit on the DVD.

As I said, DVDAS's menu capabilities are far superior to S11 so I don't know why you would use S11 to begin with. If it was because of the compression issue, don't worry, you'll get as good (probably better) render with DVDAS.

As for moving this thread to the Architect forum, I don't think that's possible. I've seen it done in other (non Sony) forums, but not here.

Thanks to both of you for your comments.
