Editing VOB files without having to reencode?

Google for MpegStreamclip, or DVDxDV, or Cinematize. The 1st one's free, the second one's about $25, and the third one's about $70. The more you psay, the more you get, but if you're just doing DV, either of the first two will work fine.

I've never noticed any quality loss from what's on the DVD disc. I use Cinematize.

Seriously Brian. I did this once for a college DVD where they wanted to edit out the appearance of VP that had since been replaced, and it really looked poorly.

Do you reencoded the demuxed footage without a quality hit?

Sure did. Looked fine.

Very best solution: ask your client for the original video tape.

Everything else is a disappointment.

for everyone.

Use stream clip to demux the ripped VOB's to .m2v and .m2a, then create a DVD Studio Pro project, and use the rough (nearest GOP) editing in the track timeline with the existing assets.

Create a new DVD from that - no decode - re-encode, no frame accurate editing either, but, quick, and easy-ish.

Obviously the original tapes would be ideal, but not always available, and possibly time consuming for a quick fix for an existing DVD.

Hope this helps.

For the record, there is NO NLE that will edit VOB files. None. Some form of conversion needs to be done in order to work with these files.

DVDs as masters is never a wise choice. Tapes are preferrable. If all they have is DVDs, then they have to know that loss of quality will occur, and they have to live with that.

Stream clip will de-mux the .vobs, and DVD Studio Pro will mux them back again into .vobs - but with the ability to strip GOPS (not frames) from the existing footage.

There is no re-encoding, the end result is identical to the original DVD, DVD SP can edit - in a rough way - DVD assets and make new ones from existing ones.

mux-ing and demuxing are lossless processes, its just a way of interleaving audio and video, not reencoding either. The original loss - the original mpeg encoding from the source footage, has already happened. Trimming ripped, demuxed assets will not re-encode them, and will not add additional loss, re-muxing them back onto a 'new' disc will have the same quality as the DVD they were ripped from.

I agree, if you decode the mpeg to something else, even uncompressed codecs, do a full, frame accurate edit in final cut, and re-encode back to MPEG2, then yes, you will get additional compression and loss.

But, that wasn't what I was suggesting. Do it all in DVD SP, which can act as a rudimentary editor on already encoded assets.

And, can the original poster mark any of the above posts as helpful or solved, if the posts are helpful, or solved the original problem. Thanks.

Can anyone tell me where to get Stream Clip - does it do anything ffmpegx does not?
