Yes there is plenty of free software out there to help you retrieve clips from your DVDs. It is a rather a long topic of discussion & can sometimes seem to be too much hard work for the end result (particularly if you are unfamiliar with these programs & DVD specs.) Having legitimate reasons & permission of the copyright owner are a must.

Editing (Cutting & joining) MPEG-2 files is another topic altogether that brings all new problems because of the nature of MPEG compression.

Try using an S-video cable from your DVD player to your camcorder (audio, too, if needed) and record the clip(s) to tape, then capture it into Vegas from the camcorder.

thanks I'll try that.

Vegas recognizes the VOB file...if it is not "copy-guarded" you can drag right into the timeline- without the audio....I capture the audio through a breakout box. Hope that helps.

This has been covered many times. Search for "VOB" and you'll get lots more details than I'll provide here.

I'm assuming this is video from a DVD you created in Vegas.

1. Put the VOB file on the Vegas timline. You'll get video, but no audio.
2. Use DVD2AVI to convert the AC3 audio to a WAV file (Audio -> Output Method -> Decode to WAV).
3. Put the resulting WAV on the timeline directly below the video. The two should end up being exactly the same length.

That's all there is to it. It is much quicker than playing the video and capturing it via an analog capture setup, and you don't lose quality (other than what was lost encoding to MPEG2 in the first place).

The DVD does not have to originate from Vegas. I have used VOB files from DVD's comming from other edit facilities...no problem. My suggestion- try it! Just drag the vob file into the timeline or media bin.

Thanks guys, that helps, I will try that.

bumping this back up as i have a follow up question that i couldn't a clear answer to.

i fully understand the converting of the vob file to the avi. my question is what kind of quality loss am i going to see. johnmeyer notes that you will only lose what you lost when you created the mpeg in the first place. not to second guess or doubt, but does anyone have any real world experience with this conversion.

and won't i lose quality when i go from this newly created avi file back to mpg and then to vob.

it just seems i've got to lose something somewhere, or will what i lose not be noticeable to 90% of the public. Finally this is more of comment than question but please respond with your opinions

does this need for conversion mean that until we get quad layered pink lasers (sarcasm) there really isn't going to be a way distribute and then re-edit materials without keeping the orignal dv tapes?

it seems the carrot never really left, they just changed its shape, from vhs to dvd disc. or am i completely off my rocker here.

Yes you will loose something in the translation which is why you want to do as little translations as possible. Placing the VOB on the timeline and then rendering back out to MPEG2 will yield only one more re-encode (from MPEG to VOB is just a stream copy). Capturing to DV AVI and then creating a final MPEG will involve encoding twice. I’m not sure most people will notice the difference if the source DVD was of high quality to begin with.

I need to amend my statement slightly. JohnnyRoy is correct that you WILL lose quality when you re-render the VOB (i.e., when you create a new MPEG file from the VOB and the audio WAV file). When I said you didn't lose quality, I was referring to the earlier posters who talked about re-capturing the DVD via an analog capture from the DVD player. This will lose another level of quality, plus it cannot be done faster than real time, wherease copying the VOB file can go at 2x - 6x real time, depending on how fast your DVD on your computer can read.

If you want to simply cut and paste existing VOB files, you could use Womble's MPEG VCR or their MPEG Video Wizard to do the editing. You would then save the result as elementary streams, and then author them back to a DVD using an authoring program that accepts such streams (basically any authoring program except DVD Architect). There would be zero loss from the original bits in the original video.
