Не пробовал. Думаю, должно хватить. Ведь Optical Flow даже у слабых видеокарт работает в реальном времени.
Вот на всякие тяжелые madVR апскейлы может не хватить. Но всегда можно умело воспользоваться менее ресурсоемкими алгоритмами, вплоть до Bicubic PS 2.0, которые дают достаточно качественную картинку.
Теория:
The NVOFA provides real time performance with small CUDA core utilization

Maybe a little. One pixel precision for 4K is visually is not dramatically differ from Half pixels.
But it works 2 times faster.
It looks like true. I've checked another rule for RAM:
Users told before the single channel mode for RAM can be the bottleneck and lead to frame drops.
The solution is to check it and to switch to double channel mode. It works for FullHD resolution.
You talk about 4K resolution. In general the solution is to increase RAM bandwidth.
Try to lower SVP profile settings.
For example, change Motion vector precision from Half pixel to One pixel.

Nice to hear!

What headset you have?
Or you watching these videos on monitor?
What resolution and refresh rate it has?
> Intel Core i7 8700K
It can interpolate 4K videos maximum in real time. I think it is bottleneck for 6-8K resolutions.
You can make some tests: take videos with different resolutions and look to SVP Index while playback with SVP. It must be 1.0 and CPU load must be less than 90%.
Мертвые зависания исправлениями SVP не вылечить. Это проблемы железа и драйверов.
Все остальное описанное выше не является проблемой.
Тут как в анекдоте "Вам шашечки или ехать"? 
why not using mpv from SVP bundle?
It is good solution to know it is tested with SVP and works with VS filters
If you want to watch 23/24 fps video without motion interpolation at 60 Hz monitor you can just use madVR and its "smooth motion" option.
Если ничему не мешает, то и фиксить не зачем.
Нагрузка на ядра - вещь динамическая, может перераспределяться между ядрами в силу разных причин, а графическое отображение весьма примерное. Смотреть надо на результат, успевают ли отрабатывать расчеты и нет ли вылетов кадров.
I've checked just now. It works. I can select resolutions 720p and 1080p and they playback correctly.
Short instruction.
1. Open https://www.crunchyroll.com and login with premium account.
2. Open in browser premium episode you want to watch, start palyback, save cookies.txt for this tab and you can switch video to pause mode.
3. Copy URL of this tab from browser = you will get SVPtube message about Preview only. It is normal.
4. In SVPtube menu open Authentication > Add website authentication data... > press "Load from text file..." and open cookies.txt file saved in step 2
5. Press "Save", wait for some time while SVPtube extract data. Also, you can open SVPtube panel manually and wait for result = you will get SVPtube panel with all avialable resolutions. Congratulation!
6. Select resolution you want, press "Play" and enjoy video.
You need to reinstall GPU drivers
Best solution is identical value of video frame rate and display refresh rate.
Also good quality you can get if refresh rate is a multiple of frame rate.
In all other cases you will get non equal durations of frames showing on your display.
In your case of 48 fps you can use 144 Hz mode because these rates are multiple by factor 3.

> What is the best choice here?
I need to compare it myself. I didn't use d3d11 cb before and I don't know the real difference with DXVA2 cb.
Do you see the difference?
D3D11 decodes frames from video stream and leaves them in video memory.
SVP needs these frames in operational memory. So, you need to use decoder that copies frames from video to operational memory.
These hardware decoders are:
DXVA2 (copy-back)
NVIDIA CUVID
Intel QuickSync
More universal decoder is DXVA2 (copy-back)
Green screen is decoding issue. Reinstall your GPU drivers first.
Your GPUs can be used for:
- video decoding
- SVP-calculating while inserting interoilated frames in video
- video processing while render video in player
- video encoding
So, you can use different GPUs for each of these tasks.
You can try to decrease amount of visible artifacts:
Artifacts issue
What are the best possible settings?
haloing issue
Artifacts around lines
Удаляем 1 кадр из 5-ти. 30 fps - это 6 раз по 5 кадров, получаем 6 раз по 4 кадра. Это 24 fps.
Удаляем 1 кадр из 25-ти. Тут вообще все ясней не бывает. Было 25 fps, станет 24 fps.
Thank you for information.
3D stereo detection must work for every video with OU, HOU and SBS tags in file name.

We will check why it not works for resolutions you pointed.
Вроде бы все понятно в справке к TDecimate написано.
http://avisynth.nl/index.php/TIVTC/TDecimate
Выкинуть 1 кадр из 25, чтобы получить 24 к/сек: cycleR=1, cycle=25. Первый параметр итак по умолчанию равен 1: cycleR=1. Поэтому необходимая строчка:
TDecimate(cycle=25)Это аниме. Я скачал первый эпизод. Видеодорожка 30 к/сек. Cам мультфильм отрисован с меньшим количеством к/сек, но закодирован с частотой 30 к/сек.
Если листать покадрово, то фон содержит движение каждые 4 кадра из 5-ти, герои первого плана - 2 кадра из 5-ти. Т.е. фон двигается 24 раза в сек, а остальное - 12 раз в сек. Это стандартно для аниме.
Необходимо достать исходник, закодированный в 24 к/сек или сделать самому.
https://www.svp-team.com/forum/viewtopi … 623#p11623
TFM в данном случае выполнять не нужно, поэтому скрипт получится всего из одной строки:
TDecimate(cycle=5)It is idea! Try to transcode video without interpolated frames (select SVP profile with disabled frame rate conversion).
Will you get 165 fps too?
