editing .vob files within Vegas..

Hi, I have a seminar set of dvds I'd like to compress down to a single DVD, by modifying the source vobs, eg compressing to mpg1, then re-authoring within DVD architect...

When I drag and drop .vob files (or, rename them to mpgs) into Vegas 4, it only shows the video stream, although the source vob contains both audio/video streams. I'd rather not have to demux 20+ gigs of vobs first, any tips on how to directly drop vob files into vegas and then render them out, edit them etc with audio intact?

thx,

ken

not possible, Vegas will only read the video stream!

The audio stream on your DVDs are, I presume, Dolby Digital AC3. Vegas will not decode AC3. Sorry, you'll have to demux the VOBs and convert the stream to WAV. Try this AC3 Decoder.

Another thing, you said you plan on "compressing to mpg1, then re-authoring withing DVD architect." I hope you mean MPEG2; DVD Architect will not burn a DVD with MPEG1. It would convert it to MPEG2, recompressing your video yet again.

Thanks - appreciate it.... right re mpg2, I remember I did this with one seminar set, eg to a 352 x 240 size and it still looks fine on a regular tv ... forgot how I did it though ... (the mind's the first thing to go lol) ...

I don't think they're dolby AC3 encoded though it's possible.

Thx for the demuxer link, will try it ..

(update: Hey that's a fast demuxer, just what I needed, thanks! )

VOB files

straight path for reauthoring

Extracting Video from a DVD image

Will Sony give us a nickel every time this gets asked? Note that in the last link provide above, I predicted that this would be a major requested feature. It needs to be in the next release, IMHO.

You can try BeSweet to demux the audio. There you can go from VOB to WAV. Please go to www.videohelp.com, hit tools and search for BeSweet (it's free!).
One ore thing: editing VOB files can be frustrating since the final result will strongly depend on the quality of these VOB files, I mean the bitrate they were originally encoded. If the quality is poor or you resize the screeen with pan and crop you'll certainly get lots of "banding".
