> Ползунок качества и устарения шумов на макс.
Это завышение настроек по сравнению с возможностями системы. Может давать неплавное движение. Проверить, что вертикальная оранжевая линия двигается плавно без скачков: меню SVP Утилиты > Тест плавности воспроизведения.
Если дергается, то вернуть ползунок качества в среднее положение. Подавление артефактов тоже рекомендую среднее. Сам смотрю с низким подавлением, либо вообще без него, т.к. подавление артефактов уменьшает плавность. Мне нравится высокая плавность пусть и с некоторыми видимыми артефактами.

> при 8к 60фпс
О! Я проглядел это. Спасибо за уточнение.
Copy-back - это по названию такой режим декодера, что вся информация о картинке из видеопамяти копируется в оперативную, а затем после обработки в оперативной памяти копируется обратно в видеопамять для отображения на экране. Здесь узким местом вполне может стать пропускная способность оперативной памяти.
Нетрудно посчитать требуемую пропускную способность: 12 бит/пиксель * 7680×4320 пикселей * 60 к/сек = 23 887 872 000 бит/сек = примерно 24 Гбит/сек только в одну сторону hmm

> I am currently using SVP to interpolate to 30fps
> How is this non integer interpolation factor handled?

If we talking about createtion 30 fps  from 24 fps then every 4 frames must turn into 5 frames.
So, 1 frame is stayed untouched 3 frames are dropped, and 4 new interpolated frames are inserted instead of them.

> When using the "2m min artifacts" mode the wiki says that each original frame is used twice.
> How about 30fps then?

If we stil talking about 30 fps interpolation from 24 fps then:
- original pattern is 1234 (where 1, 2, 3, 4 - source frames numbers)
- uniform frame intepolation pattern is 1mmmm (where 1 - source frame, m - new interpolated frame)
- 2m interpolation mode pattern is 11234 (no new interpolated frames at all)

2m mode is useful for 60 fps from 24 fps intrpolation and any interpolation with factor more than x2.

А частоты ядра и памяти при этом какие?
Были случаи, что частота GPU не поднималась при воспроизведении видео. Эта проблема как-то решалась.

black and white colors you can get if you have AVS 3.5. You need to update it.

B/W image or any other issue playing via Avisynth Filter: ensure you have Avisynth+ 3.7.2 installed! Note that SVP installs AVS 3.5 by default.

Возможно, это из-за разной частоты кадров на выходе.
В SVP 4 может быть включено удвоение кадров. Загляните а настройки профиля и включите повышение плавности до частоты экрана.

You need to lower CPU usage. See to CPU load value and change SVP profile settings to make it lower.
SVP menu Utilities > Performance monitor

Also you can use video with lower resolution. The lower resolution the lower CPU load.
Also you can use another player and another video renderer to reduce CPU load by rendering compltely with GPU.
MPC-HC menu View > Options... > Output tab > Select:
- MPC Video Renderer; or
- Enchanced Video Renderer (Custom presenter) with D3d Fullscreen option enabled and Bilinear Resizer.

OBS Studio

Насчет более 60 к/сек - надо смотреть. 60 кадров точно записывают.

You can use two GPUs to separate tasks between them.
GPU-accelerated tasks:
- video decode
- SVP math
- NVOF
- Pixel Shaders
- video encode

What video player are you using?
You can do it with your player settings.
For example:
MPC-HC. Hotkey "gray+/gray-" to adjust audio delay by +/- 10 ms.
mpv: Hotkeys "Ctrl +"/"Ctrl -" to adjust audio delay by +/- 0.1 seconds. https://mpv.io/manual/master/#keyboard-control

Start from change video renderer in MPC-HC player to MPC Video Renderer instead of madVR.
Then look to GPU load and how smooth video working. Find bottleneck then adjust it to work faster.

GPU can be used in different manner.

Check please your mpv.conf file. Do you see any vflip commands there?
https://mpv.io/manual/stable/#video-filters-lavfi

If not, you can try to flip picure backwards vertically.
---

Fast fix is to make new file input.conf near mpv.conf or edit it. You need to add line:

g vf toggle vflip

and press 'g' while playback. It will flip picture vertically every press this button.

P.S. You can use attached file.

I've downloaded both videos.
First video has 60 fps. And it has only 30 different frames per second. You can look at video from time 3:02 in pause mode frame by frame. Every second frame is a double
So, to get smooth video you need to remove each odd frame first.
SVP Video profile setting:

Duplicate frame removal = Remove every over frame

You don't need many steps. Only two:
1. Login in your browser to your Youtube account and save cookies file.
2. Set cookies file in SVPtube. Only cookies nothing more.

Cookies has restricted life time. So, you need time to time repeat these two steps, when it needed. Once a week maybe.

I understood now.
You can playback video in MPC-HC player at x3 speed. SVP will detect it and properly interpolate to desire framerate.
Your example 24 fps --- speedup x3 --> 72 fos --- interpolate x2 --> 144 fps

But you need to allow SVP to interpolate high framerate sources:
Open SVP profile "Ignore HFR sources" and change condition: increase value of Video frame rate from 47 to 80, for example.

If copy-paste fragment then it will not work at all.

Proper format introduced in file override_list.txt:

analyse.main.penalty.lsad        = 8000;

If fix all errors then it must become:

analyse.block.overlap = 2;
analyse.main.levels = 6;
analyse.main.penalty.lambda = 10;
analyse.main.penalty.lsad = 16000;
analyse.main.penalty.pglobal = 50;
analyse.main.penalty.plevel = 4;
analyse.main.penalty.pnbour = 100;
analyse.main.penalty.pnew = 100;
analyse.main.penalty.prev = 0;
analyse.main.penalty.pzero = 75;
analyse.main.search.distance = -1;

You can read about each setting here: https://www.svp-team.com/wiki/Manual:SVPflow
And if remove all default values you will get:

analyse.main.levels = 6;
analyse.main.penalty.lsad = 16000;
analyse.main.penalty.plevel = 4;
analyse.main.penalty.pnbour = 100;
analyse.main.penalty.pnew = 100;
analyse.main.penalty.pzero = 75;

I didn't check how works these settings so you can use them for you own risk.
