You can play with ffmpeg's tonemap filter
Switch to 'advanced' mode, put something like "zscale=transfer=linear,tonemap=reinhard,zscale=transfer=bt709,format=yuv420p" into lavfi field, set depth = 8 bit
This will do 10-bit HDR to 8-bit SDR conversion using reinhard tone mapping.
We'll think how to automate this in a future SVPcode build...
In fact, mpv does tone mapping via compute shaders on GPU. And all that GPU processing is not active in encoding mode.
Not sure now what we could do about this 
конвертация в SVP - это граф. оболочка для запуска mpv с нужными параметрами
как-то странно делать запуск из консоли графической оболочки для вызова консольной же программы
что мешает запустить да узнать, работает или нет?
но вообще вроде когда-то работало...
SVP does transcoding via mpv player which is unable to preserve HDR meta-data after encoding. It can only do tone mapping (i.e. "conversion") from HDR to SDR.
check video decoders, ensure you have "copy-back" enabled
Not sure that 30->120 is any better than native 60 w/o interpolation
I personally think that 60->90 or even worse - 60->80 - is not worth it. 60 fps sources are already "good enough".
60->120 could make sense though, for a 120 hz headset.
As for me - 24 fps stuttering is "hurting experience" a way more 
> How do we get DeoVR to support SVP for HEVC, is it just a matter of petitioning the DeoVR developer?
yeah... they must provide a way to append ffdshow raw filter to the filters list
run the same command from the console
Sorry, I can't check this in the following two weeks cause I'm on vacation.
However in my own tests Avisynth 3.6.x seems broken - don't use it!
https://github.com/AviSynth/AviSynthPlus/issues/178
It uses the most suitable profile.
If you want specific profile for online streams you may set the "is network stream" condition.
I only have access to the PC with RTX card remotely now, and this particular PC just turned off yesterday (probably because of another Win10 update). And I won't be able to turn it back on in the following two weeks 
I'll try to figure out what else could happen in the last update.
1st thing is about adding that smooth.scene.limits.ignore option that must affect panning smoothness and the 2nd one is about 24-px NVOF grid.

it would be helpful

you can only replace svpflow2.dll with an older version
DirectShow 64-bit: https://www.svp-team.com/files/repo/ful … ugins64.7z
but this thing - "improve smoothness of panning scenes in some cases" - IF it is the reason of the issue - can be turned off in the current version by setting 'smooth.scene.limits.ignore = 0' in override.js
it looks like it must work
can you run mpv from the Terminal? like 'mpv <some-video-file-here>'
вроде, никак не связано
я бы предложил изучить логи!
seems to work after updating too...
BTW I'm using mpv-full AUR: https://aur.archlinux.org/packages/mpv-full/
Quaternions, Arch too?
I can only think of a conflict with a system-provided jsoncpp, as libsvpflow* are _statically_ linked with modified jsoncpp to allow "simplified" JSON w/o extra quotes.
But I can't reproduce this behavior, SVP works fine on mine Arch VM.
Will try to updated it to the latest version now, will see...
I'm not really a mind reader. Try this.
overheating -> cpu frequency dropped
different codec
variable frame rate
any errors in the terminal output?
run 'brew info mpv'
