mpv already has several tone mapping algorithms built-in
https://mpv.io/manual/master/#options-tone-mapping
MPC-HC 64-bit
I think both are enough for 4K and both are not enough for 8K.
Current problem is 4K 10-bit can only be viewed in mpv, and mpv performance in this mode is abnormally low, but I hope it will be fixed/improved somehow.
if you need it to run Cinebench then yes, 2 CPU 20 cores will be better
the thing is most people don't buy PC specifically to run Cinebench 
> SVP does not support 20c40t?
it should work... somehow
> Blu-ray bitrate is very high, need performance beyond ordinary 4K video
this's not a question of bitrate, SVP works with uncompressed video stream
this's about 8-bit vs. 10-bit vs. HDR thing
> blu-ray 4K
there's no simple answer to this

I personally would prefer single new Ryzen 2700X over used 20 cores server monster...
а оно мешает? нажать ignore
потом если сам SVPManager не будет запускаться, то смотреть что не так в консоли...
> The SVP index wasn't high enough for profile settings 1 and 3?
for playing in mpv - yes
> would 4k h.265 8-bit video use up the same amount of CPU to interpolate as 4k h.265 10-bit video?
nope, considering you're using hardware decoder, h.265 8-bit need the same CPU power as h.264 8-bit
HT gives wrong CPU load numbers. "50% CPU load with HT in Task Manager" can mean anything from real 50% to actual 100%.
My CPU shows 45% load with HT and 90% w/o HT with the same settings. But it doesn't mean "HT gives x2 performance boost".
зависит от того, можно ли влепить на XP VC++ 2017
я не знаю, не смотрел...
> Lav теперь и вовсе не поддерживает Windows XP.
следующий на очереди - Avisynth+

никаких

Ryzen 7 8-cores, MPC-HC 64-bit - SVP @4K CPU load is less than 30%
at highest "auto" settings (and Ryzen 7 at 3.4 GHz loaded up to 50% in this mode)
Actualy, these are not entirely true
CPU load numbers are half-fake because of hyper-threading turned on.
Here's one more attempt, with Ryzen 8-cores at 3.4 GHz and HT off:
"lvl" = SVP "auto" profile level, 1 is highest settings.
lvl / MPC-HC / mpv
4K H.264 (8-bit)
1 / 90% / 100%, SVP index < 0.9
3 / 70% / 85%
5 / 60% / 70%
4K H.265/HDR (10-bit) -> 8-bit
5 / 60% / 85%
4K H.265/HDR (10-bit) -> 10-bit
Is not supported in MPC-HC, and is not playable in mpv - 60% CPU load while SVP index stays below 0.8.
1. mpv needs more CPU power (~by 20%) for 4K playback than MPC-HC
2. 10-bit 4K is a no-go in current mpv version - something is limiting performance very badly
===
For 1080p 10-bit HDR difference is not so huge.
MPC-HC (8-bit) - 25% CPU load
mpv (8-bit) - 27%
mpv (10-bit) - 34%
BTW, 10-bit mode in SVP is kind of broken - intermediate frames are rounded to 8-bit and colors are incorrect. Will be fixed ASAP.
and the version of mediainfo package is...?
segfault in libmediainfo.so
never seen this before
try to update it to some newer version (if any)
> SVP @4K CPU load is less than 30%
let's say "50%" (at the highest "auto" settings and Ryzen 8-cores at 3.4 GHz), 8-bit video
it asks for ffmpeg path
64-bit MPC-HC uses 3.7 GB of memory for 24->60 at highest "auto" settings (and Ryzen 7 at 3.4 GHz loaded up to 50% in this mode)
32-bit MPC-HC can't even reach 1.0 "SVP index" because it's memory bound with these settings
there's an "all files" option in that window
main.setup.min_duration = 0
it should work for streaming video too
what do you see in the SVP's log?
> Could I also disable SVP and use SVP cast to passthrough 4k 24fps content with HDR?
nope
dunno, turn off or on hardware video decoder, for example
"h.264" in software mode or NVENC?
In the streaming status window there's a colored encoding performance indicator. Does it show stable 60 fps speed?
Another thing to try: "cast.encode.opts.realtime = false" in All settings. This will turn on another encoding mode when it will "pre-encode" some video as fast as it can, at full 100% CPU load.
