Yes, manono is right. Of course, my example is a extreme case to ilustrate the need to choose the right encode parameters. Supose you want your movie to fit on one CD. If you keep the original resolution you get high quantizers (and low quality). If you reduce your resolution you get fewer high quantizers (and a superior quality.) This is true, also if you overreduce your resolution. In the middle, there are one point with the correct resolution to get the bigger visual quality (not the bigger Nandub quality). So, you can only compare the Nandub quality if you had choosed the correct resolution (with the help of GordianKnot, maybe). And, also the smoothers, the quantizer distribution (curve tweak), etc. can modify the visual quality without a direct relation with the nandub quality. Pandv.
