I've actually tested the settings on 2-3 other sources, and while the bitrate always went down, I noticed that in some cases the SSIM was a bit lower with the last settings than with your settings. Looking at the files, some frames looked better with your settings and some better with the last settings (in my original test clip, the last settings looked better for every frame I looked at - this is all subjective of course).kvaruni wrote:Wow, thank you Rodeo,
to be honest, I hand-picked these settings from about 40 different sets that I tested over various RF and I never imagined that they could be further improved. I like it that you set the partitions yourself and I never even considered that this would offer me better compression, speed and file size. I will try your settings in my next batch of encodes, probably tomorrow. In case you know of any other way to tweak these settings, I would be more than happy to hear them!
