Question re "lossless" extraction of clips for later DVD authoring

[TURB0x]

Hi!

I'm currently in the process of collecting material for a DVD compilation of music videos/TV appearances of a certain band. In doing so I've collected a number of DVDs with full TV shows on which this band appears and plays a song or two. My question is:

How do I extract/backup the relevant clips/portions from the different DVDs (for future authoring) without losing any quality or reencoding them?

I've been using VideoReDo TVSuite for extracting MPEG2 clips from DVDs in the past (for YouTube purposes) - but is that the best way in regards to preserving quality? Is it 100% "lossless"? Or is there a better way?

Any help regarding this would be much appreciated.

Videoredo extracting is lossless if you save as mpeg2. It wont reconvert.


You can also the free dvd shrink under the reauthoring section to cut out vob clips without reconverting.

Man tackar!

When I'll compile all the clips to one single disc - does it matter if they have different aspect ratios and bitrates as long as they're all in the same basic video format (i.e. PAL)? Or do I have to re-encode them to match each other in those areas? I'm planning to use TMPGEnc Authoring Works 4 by the way.

You can mix different aspect ratios if you create separate titles/tracks for them in tmpgenc authoring works.

Ok, thanks for the help!
