none is better or smoother
difference is more threads could rise GPU utilization in case it's too low while output fps is not enough
а если сейчас?
ещё раз обновление запустить
> Although, anywhere above 48 fps my GPU usage sky rockets from 46% to 90%
because x2.5 interpolation (i.e. 24->60 fps) need generating TWO times more intermediate frames than x2 (24->48)
> I added another model from github and when selected I get a flickering sensation on any video
then add another model 
and post a bug report on the Github regarding the flickering one
"Number of devices: 0" как бы намекает, что что-то тут не то
SVP updated

RIFE/CUDA removed from the script completely
> and leave 4.4
why 4.4? just because the numbers are higher than 4.0?
ok, 4.0 was removed from the list, but 4.2, 4.3 and 4.4 are still there, w/o any changelog or something like that
is 4.4 better than 4.2?
it won't work on a 7 yo SoC
> Do you plan to update SVP with the newer models?
kind of... not exactly like this
there will be only ONE model bundled (*), plus you'll be able to add whatever model you want manually, by copying model's folder
(*) if you _know_ which one from 4.0 to 4.4 is the best in terms of overall quality - this is the right moment to tell
> without losing 10-bit colour depth and HDR?
yep
> I would very much encourage everyone to share their observations
buy a video card at last!
> Is there an improvement in quality and speed of interpolation?
no idea about quality, but 4.1-4.4 performance is the same as 4.0
4.5-4.6 are 10% _slower_
> на AMD Radeon SVP будет работать
если попрыгать с дровами, то будет
too bad... dunno what we could do about it right now
need to figure out some workaround 
actually I need what is below this - the list of CDM's
> But inside it's still 4.5.0.212
yes, but with the latest yt-dlp inside
there actually WAS an update a few weeks ago

you will see it now
please run the app called "DRM Info" (there's one in the AppGallery) and post results here (via screenshots, I suppose)
> SVP allows real-time interpolation for 4K 10-bit HDR files, but needs Avisynth Filter for this
"Avisynth Filter" is a confusing naming cause there're _two_ different filters there, one for Avisynth and one for Vapoursynth
both supporting 10-bit and hdr
> It is said that the performance of Optical Flow is also improved by about 2.5 times
it only makes difference for interpolating 4k@60 to a higher rates
> will AviSynthPlus-RIFE work with 4K 10-bit HDR...?
exactly the same as it work in vapoursynth-rife
> would you be able to implement this new AviSynthPlus-RIFE into SVP
yeah, will do... but there's no noticeable difference with a "Vapoursynth filter" - load times and performance are exactly the same
plus it requires an unreleased AVS+ build, crashes with the latest official release
Just built vapoursynth-rife-ncnn-vulkan on Apple M1, and it only makes 50 fps out of 704*528@30 source video with v4 model.
Not exactly the performance I expected...
But at least it works, which is good news 
да даже 4*4 иногда странно выглядит, еще мельче кмк особого смысла нет
плюс дальше обработка идет через CPU (пусть потом и заворачивается обратно на GPU), т.ч. в текущей архитектуре SVP вектора 1*1 просто положат проц, а на 4к так и 2*2
да и еще хз откуда они там берутся эти 2*2 и 1*1
в SDK для 2ххх они тоже были, но тупо считались интерполяцией из 4*4 в самом SDK
может в 3ххх это такая же интерполяция, но "спрятанная" в драйвер, мы ж не знаем
а если так, то смысла в этом никакого нет, SVP и так делает интерполяцию векторов до 1*1, но на самом последнем этапе
> Собственное удвоение кадров. Очень жду имплементации.
в минимальном виде это будет просто передвижение точек по тем же векторам, ну плюс какой-то интерфейс чтоб это где-то использовать, с ffmpeg например
но если выложат какой полезный алгоритм маскирования артефактов - тогда хорошо
