To what values should i modify the custom mpeg quant matrix so to achieve near lossless compression using quantizer mode=1 ?

Well if you were a glutton for punishment, you could just set the quant matrices to be all 1's, thus the DCT coefficients would be as close to lossless as possible.

But that'd just be weird.

Plus, custom matrices are broken at the moment (or so it seems).

If you really really want lossless compression, stick to huffyuv for the time being ;)

Ok thanks :) I'm going to wait for a new fixed version.
