такое обычно если time_base не указан. но он должен подставляться в ovcopts автоматом

let's take a 1920*1080 video as example

top (higher) level (#1) for the "hierarchical search" is the frame itself - 1920*1080
next one #2 - the frame reduced by 2 in each dimension - 960*540
#3 - 480*270
#4 - 240*135
bottom (lower) level #5 - 120*67

top level = "finest" level
all other bottom levels are "coarse" levels

the search parameters are _different_ for coarse and top levels
levels from #5 to #2 - more exhaustive search, level #1 - simplified search

with this "width of coarse level" option we can move this "line" down: levels 5 to 3 - exhaustive, levels 2 to 1 - simplified

and this is more important for 4K video

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...

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

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.

Not sure that 30->120 is any better than native 60 w/o interpolation

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

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!

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.

> Does someone know if there is a way to download an old version?

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
