the quant/psnr/size relation is very complex ... for example encoding one frame with quant=3 and one with quant=5 is sometimes better, sometimes worse then encoding both with quant=4, for example very low motion scenes need only slightly more bits at lower quants, but look much better, while high motion scenes will need much more bits at lower quantizers ... and the quant/psnr/size relation of frame n will significantly depend upon the quality of frame n-1, as its used for motion compensation
Is there any recommended reading about this ? I dont seem to be able to find anything that explains such stuff. Attila Kinali -- Emacs ist für mich kein Editor.
