gpu-next best interpolation settings

[lavilao]

Hi guys small question:
now that mpv has a new renderer (vo=gpu-next) do anyone knows what are the best interpolation settings for it?
on vo=gpu after testing the best settings were

video-sync=display-resample
interpolation
blend-subtitles=yes
tscale-window=quadric
tscale-clamp=0.0
tscale=box
tscale-radius=1.025

on gpu-next you can't resize the filter [vo/gpu-next] Filter radius specified but filter 'box' is not resizable, ignoring and I also read on the manual about a new interpolation option interpolation-preserve those two things make me wonder if there is a new "best interpolation settings", so there is it or it is the same? will gpu-next sometime in the future get a hardware accelerated motion interpolation feature like splash player (plead to mpv devs)? thanks in advice!

Hrm, actually the issue is that this setup can't be recreated as-is because quadratic is not reiszable either.

I think I'll fix this by reimplementing the old box behavior (effectively making it different from nearest).

thanks

I found

tscale=sphinx
tscale-blur=0.65

to work well. With all the motion blur that is already contained in real world videos, you might even go as low as 0.6. Though that already looks a bit juddery with synthetic judder test videos.

@aufkrawall wow thanks for the suggestion, it looks really good and are a lot less (relatively speaking) lines of config

I remember that hassn mentioned something like this for gpu-next:
tscale=sphinx
tscale-blur=0.6991556596428412
Been using this ever since. And "0.6991556596428412" is so exatct! Is this the magical number?

[lavilao]

that is a exact number xD

@aufkrawall Does it work on vo=gpu?

[aufkrawall]

As it doesn't print any warning with gpu, I haven't noticed any issue and nothing is mentioned on the https://github.com/mpv-player/mpv/wiki/GPU-Next-vs-GPU page, I see no reason to assume why it shouldn't work.

Closing since this is a meta-discussion with no final answer, and a bug tracker is (IMO) not the right place for those.
