here is shortened command list for preset veryslow...

with my custom settings, switching to placebo only changes subme=4 to subme=7, & tskip is enabled, (i only like tskip for cel animation)... i went with subme=4 over 5 or 7 because it tends to look better more often then subme=7, especially in flatter areas like the lady's face in the video... however the subme=7 encode is smaller in file size, slightly, from 18002 KB to 17933 KB for the sintel clips below (52 seconds at crf 18.4)...
below is an encode with my custom settings & another encode with with my custom settings + subme=7
sintel_trailer_2k_1080p24____crf=18.4____custom__(subme=4).mkv (preset=veryslow)
sintel_trailer_2k_1080p24____crf=18.4____custom_+_subme=7.mkv (preset=placebo)
i added aq-mode=3 because aq-mode keeps coming out to a 2 in mediainfo :/ shouldn't it be 0 since hevc-aq takes place of aq-mode=x? is this a handbrake only bug?
---
does rd-refine not work with hevc-aq?
if i specify aq-mode=0 (with hevc-aq) i get an error saying rd-refine requires adaptive quant...
---
i listed tskip, but technically veryslow already has tskip disabled, and as you know ;) placebo has it enabled, i quote you below.
