My DVD to be edited on mac?

Jeff_Smith wrote on 2/23/2006, 4:09 PM
I have a friend that wants to put my DVD media into his own new authored DVD. He is on a mac with FCP DVD studio pro. I do not have my original source files, only a DVD. Worse case I could play my DVD and record analogue out to my DV cam and give him the tape to re-capture. What kind of regen hit would that be?

Or, If I just give him my DVD, should he be able to extract the mpeg files from the DVD?

Or is there a way I can create a mac friendly mpeg file for him?

Thanks,

Jeff

Technically, there shouldn't be a problem with extracting the MPEG-2 video and AC3/PCM audio streams from your authored DVD. However, while properly rendered MPEG-2/AC3 streams should work in any DVD authoring application regardless of platform, different authoring apps will be picky about different settings that another app may not be (and vice-versa). For instance, some apps require audio/video assets be imported as elementary streams, while others recommend program streams.

I'm not too familiar with tools to demux VOB files on the mac side, but there are several on the PC side. Perhaps you could extract files on the PC and give him those files. Should be easy for him from there (depending on the authoring app he's using).

If he decides to go the analog route, he should be prepared to lose 2 generations: one by transferring, and another in encoding to MPEG-2 (lossy compression). Depending on how good the connections and the encoding are will determine how bad things look in the end. All in all, this is NOT the recommended method. Demuxing the DVD is far better, faster, and not really difficult at all IMHO.

How do I do that?

He would prefer one big MPEG-2 file DVD studio can read. I tried taking my VOB file and just changing the name to *.mpeg. The file will play in my wmp but not QT.

You need to demux the vob file.

There are numerous tools to do this. One such program is TMPGEnc.

Otherwise, Doom9.net has a list of tools for various tasks relating to working with DVDs.

I'll give it a whirl.

Or - you could use Vegas 6, and the "Import DVD camcorder disc" feature,
and render it as an AVI or Quicktime, which will import into final cut!!!
This was a feature of 6.0c and I assume 6.0d, and I found it very useful!!
Don't forget to render as progressive scan, and click reduce interlace flicker, though.....

You could do that, but doing it will mean losing 2 generations (depending on what codec is used to render to quicktime).

If no editing is needed, then keep it as a MPEG-2 file and don't re-encode it unless you have to.

so why not make a copy of the DVD and give it to your friend to try to extract himself? I've burned DVD's with DVDA that have been extracted on Macs however I've never been able to just open a DVD done in DVDSP that didn't need to be demuxed prior for work in Vegas.

Don't think your mac buddy will have a problem at all.

That's what I am going to try first, I was hoping to hear from someone who has done this before.

My mac buddy could not extract the files from the dvd i gave him, he could copy the dvd though. I tried the tmpgenc freeware, that does not seem to convert vob to mpeg, right? The trial version of tmpenc 3.0 xpress did work for me. Is this demuxing?) I just used the default settings, my new mpeg file seems a bit more aliased, wondering if I used the wrong settings.

Are there any other freewares that will convert dvd vob files to mpeg? I checked the doom site and tried 2 with no luck

Ok, for demux a VOB file or to convert a VOB file to Mpeg 2 with AC-3 sound I use "Mpeg Video Wizard" www.womble.com

If you respet the same settings or features of original VOB file, u will get a quick convertion, if ur PC is quick too.

Hello Juan,

Thanks for the suggestion, I tried it and end up with mpa and mpv files using Tools>MPEG demultiplexer. I think this is going to work.

John, thanks for the link but I have not tried it yet.

Using Tsunami, all I can figure out is to make one MPEG from my DVD VOB that will not play in QT. Don't I need to have both separate audio and video files?
