Converting VOB to MPG

[mephoneno]

I used DVD2oneX to copy a disk and reduce the file size.
I don't have a DVD burner so I want to put the film on two CDs as an SVCD.

DVD2oneX gave me a 1G and a 675MB VOB files. If I change the extension from VOB to MPG, QuickTime will play the video but not the audio. Using VLC I can hear the audio.

I tried to split the larger file using VPC and TMPGEnc mpeg tools. When I split the file with TMPGEnc, I got a file with no sound. No sound in QT or VLC. There wasn't an audio demux session in TMPGEnc - I think there should have been one...

Can someone tell me what I need to do to get the larger file cut with the audio intact? Is there a Mac mpeg cutting app? Are VOB files with the extensions changed to mpg really mpg files? I tried converting MPG2MPG with VCDGearX 1.0, but still no sound in QuickTime...

Thanks for any info.

Most DVD .vob files contain Dolby Digital for the audio portion of the file, and Quicktime does not support Dolby Digital audio for playback.

To answer your question, yes there is a mac mpeg splitter

mpgtx wrap. (you can get it here: http://www.versiontracker.com/dyn/moreinfo/macosx/15987 )

However, i have never renamed a .vob to .mpeg and split it like it was a .mpeg. maybe it works, maybe it wont.

Id suggest demuxing the .vob (with bbdemux http://www.versiontracker.com/dyn/moreinfo/macosx/14618 ) to get out the .m2v and .ac3 streams.

since you are making a svcd you will HAVE to change the audio to .mp2 since thats the "standard" format for svcd audio (.mp2 at 44khz) I have heard that some svcd's can be made with .ac3 but who knows if your particular player or however you will play back this file can handle the .ac3 format. best bet is to use ffmpegx to convert the .ac3 to .mp2 at 44khz
(Load ffmepg, select your .vob as the source file, save a location as xxx.mp2. Unclick encode video, and to to the audio tab, set it to mp2, 44khz and 128k/sec . I think you set the coded on the video tab to passthough or something like that (the one with ffmpeg at the end) click encode

you now get a .mp2 thats svcd standard. Combine that with your .m2v you extracted using bbdemux with this .mp2 in the mux section of tools, you now have a .mpeg thats more SVCD standard

You can decrease the k/sec of the audio if you want to try to fit these all to 2cd's instead of 3. thats for you to decide, and for you to encode the video down to the k/sec you caluclate.

otherwise, you can now split this .mpeg with mptx.

I would say just do a dvd to svcd mehtod rather than using dvd2one.

this way you will get .mpeg2 files that are presized to fit to cdr

AntnyMD and galactica -

Many thanks for the replies and the info. I'll try galactica's instructions for converting the audio, then I'm going out to buy a DVD burner.

It will work (for SVCD method to get these to cdr)
If you get a dvd burner, then all you have to do is simply burn them to a dvd.

Either way im sure you will be happy.
