Redoing DVD/Quality loss?

kentwolf wrote on 11/22/2003, 9:06 AM
Question: If I were to record a DVD I made back to my computer from a set top DVD player via a Canopus ADVC-100 so as to recapture the video and reconstruct the DVD structure, is there a noticable quality loss/hit?

I have read of people doing that, but before I go to the extra equipment expense, I was wondering as to people's experience on doing this.

Thanks for any input!

Why not just copy the VOB files back to your computer and use them? These copy much faster than real time, and you don't have any quality loss from the "re-capture." Lots of posts on how to do this and bring the VOB files into Vegas (just search on VOB).

I will double check, but I have not had good luck doing this.

I have had VOB's with out of synch audio as well as stuttered VOB playback.

I know it sounds like a good way, but I hadn't seen it work well in practice.

I am also concerned about recompressing mpg2 files.

I will double check this though...

Thanks!

1. Put the VOB on the Vegas timeline.
2. Use DVD2AVI to encode the audio to a WAV file.
3. Put the WAV file under the VOB file.
4. Encode the combination to a DV AVI file.
5. Edit the resulting DV AVI file.

Step 4 is not necessary, but it makes the editing smoother and easier.

If you need more help on DVD2AVI, use that as the search word to search in this forum (you can use my user name as well).
