How do I extract a few thousand frames from a dvd

[irasnyd]

I am looking at making some short tests to compare codecs, but I can't figure out how to get small sections (a few thousand frames, or 2-5 minutes or so) off a dvd.

Can someone help me out?

PS - Sorry if this is in the wrong forum, but this was most appropriate I thought.

Well, there are lots of ways, assuming you have ripped the DVD to HD first. In DVD2AVI you can use the [ and ] buttons to select a piece anywhere in the movie. In AviSynth the commands trim and SelectRangeEvery are very useful. The latter is the one used for compression tests in GKnot and Enc.

Or you can cut the vobs into smaller pieces using VobSplit (http://www.doom9.org/Soft21/Vobtools/vobspl26.zip) or ChopperXP (http://www.doom9.org/Soft21/Vobtools/chopperxp.zip).

You can choose only one chapter to extract from DVDdecrypter. it will save you 30 minutes of ripping....

I personally prefer to use the trim option in .avs file. pick the scene you want, give a start frame and an end frame. Encode like a full video and look at the results. I do this on every video, especially with divx to see the effect of PV level.

Cool. Thanks for the replies everyone, this worked great.
