How about an MPGShrink?

[usg]

With the growing popularity of HDTV and HD captures, it would be useful to modify the DVDShrink to work with TS and non-DVD standard mpegs to shrink to a manageable size. For example, the TS capture for a typical HBO movie capture is more than 2 DVDRs. If we can shrink the data to 2 DVDRs(or 1 D/L) w/o sacrificing much on quality, most people would not need to re-encode it to DVD/Divx/XVid etc for storage.

It should not be a big/complicated undertaking since the underlying transcoder engine(from DVDShrink) may be used w/o DVD standard restrictions.

Any thoughts?

ReJig (http://www.videohelp.com/tools?tool=449) does the same sort of thing, but on MPEG files.

I think you'll find, though, that you can't requantize the video as much as you want to (~9.4GB to ~4.7GB is 50%, much more than that may not be possible), and it will look bad.

you can enter values down to 0.0001% or something like that
but (of course) it can't go that far
it can go further with cleaner sources than with noisy ones
of course from a certain level on (downwards) the loss will be visible
but it is the best (only) free&open-source transcoder i know
you should try it out
also: test the results on the tv you'll use (classic tv's are much more forgiving to artefacts than monitors, and you also sit further away)

Thanks for pointing towards Rejig. Has some one tested it by transcoding HD (1280x720 or 1920x1080) files? Anyway, I will give it a try. Can it work directly with a TS or a MPG/M2V is necessary? Thanks.

you'll have to try
