Обработка в AviSynth:
LoadPlugin("ffms2.dll") # модифицированный FFMS
FFVideoSource("ProRes.mov", Enable10BitHack=true) # ProRes, 10 bit, 4:2:2, 1920x800
GradFun3(LSB_in=true, LSB=true) # deband
# Цветность из 960x800 переводим в 960x400:
W = Width()/2
H = Height()/4
U = UToY8().Dither_resize16 (W,H, src_left=0.25, U=1, V=1)
V = VToY8().Dither_resize16 (W,H, src_left=0.25, U=1, V=1)
YToUV(U, V, last) # собираем 1920x800 4:2:0
DitherPost(mode=6) # более требовательный к битрейту, но красивый дизеринг
AddBorders(0,140,0,140) # черные полосы до 1920x1080
Настройки x264:
--preset veryslow --tune film --crf 13
--bluray-compat --level 4 --keyint 48 --open-gop --bframes 3 --ref 4 --slices 1 --vbv-bufsize 15000 --vbv-maxrate 15000
--colorprim bt709 --transfer bt709 --colormatrix bt709 --sar 1:1
Битрейт нужен небольшой, так что ограничение скорости чтения 15000 (вместо 40000) стОит 2-секундного GOP и 1 slice. Blu-ray требует максимум секундного буфера (тут - 15000) а это уже и BD5/9.

Звук - FFAudioSource достал PCM из MOV в обычный WAV, далее tsMuxeR перевел в блюрейный PCM.
Структура Blu-ray - tsMuxeR.
