The sweet spot. This enables features like rect and amp (Advanced Motion Prediction) that make x265 significantly more efficient than x264.
Improves compression efficiency and detail preservation significantly over rarbg x265 encoding settings better

-c:v libx265 -crf 20 -preset slower -tune grain -x265-params "bframes=8:no-sao=1" Key Improvements Over Standard Releases leaving more bitrate for video.
is superior because it ensures consistent quality regardless of how complex a scene is.
This yields a smaller total file than RARBG’s audio, leaving more bitrate for video.
