Oh man. I THINK I finally found a solution for my neverending problem with red areas getting blurred and/or blocky.

People already gave me a hint to use 10bit encoding or playing around with the crqpoffs parameter. Both didn't really help.

This changed drastically now after I converted the source to YV24 colorspace and encoded it with Main 444 10.

Suddenly the crqpoffs parameter started to work wonders and setting it to -1 already brought back most of the details.


How to do it in StaxRip 1.7.0.6:
1) Click on the "AVS Filter" label. Click "Profiles".
2) Find the [Misc] section and add this line to the bottom: ConvertToYV24 = ConvertToYV24()
3) Add the Filter now via right-click -> Misc -> ConvertToYV24
4) Go into the x265 encoder settings
5) In "Basic" chose the Main 444 10 profile.
6) In "Rate Control 1" set CR QB Offset to -1.
Meh.

And now I reallize that with Main 10 444...
a) ... the contrast is too high in VLC
b) ... the video won't play at all in Windows Media Player
c) ... while it works well in Kodi and Zoom Player.
