New RIFE filter - 3x faster AI interpolation possible in SVP!!! (Page 80 of 85)

@pensioner600 The mpcVR devs are looking for you:

4.26 was the worst for me as well in my testing, it was very stable in some scenarios, but horrible in others.

If you never tried 4.25 by the way, give it a try. I use it instead of 4.18 now for 4K ≤ 1699 frame height. If you have the 4090 you can use it for everything.

RTX 3090 and I didn't upgrade to the 4080 Super because I saw reports before that people who upgraded struggled.

But surely it depends on which model you are using.

First of all, I recommend testing with RIFE 4.9

Second test with v2 Models, as they perform better. But you need to scroll up and find the files on the last page or page before that to replace, so it fixes screen shake issue that happens with v2

Third, overclocking MEMORY clock speed helps RIFE performance.

This below is basically the reason why the RTX 3090 outperforms the 4080 and 4080 Super with RIFE, someone can correct me if I am wrong:

Watching 1080p anime with RIFE set to 60fps and with MadVR postprocessing to 4K. 4080 Super, AI 4.9.

I'm finding that with RIFE TensorRT, outlines and edges shimmer (the outline width noticeably changes) when panning or scrolling happens. This does not happen with RIFE ncnn/Vulkan or standard SVP interpolation. I tried changing AI models and they all do this. Disabling MadVR doesn't seem to fix it either; it happens with all renderers. It's off-putting enough that I've stuck with standard SVP interpolation for now. Is there a fix for this, or is this a known issue? There's no point in the performance increase of TensorRT if it looks like dogshit.

This is a 1440p60 file so please watch it at 100% zoom. First I play it with standard SVP which looks great. Then I replay it with RIFE TensorRT. Focus on the uniform edges, specifically the shoulder crease marks. This becomes very obvious when blown up to a large 4K TV.

I can get 1080p120 with TensorRT and MPC Video Renderer, using 90% GPU. I can get 1080p60 with TensorRT and MadVR with the NGU Sharp scaler set to High, along with some other postprocessing like Sharpen/Crispen/Thin Edges. This uses 80% GPU, and is what I normally do because my Sony TV can then use its own Bravia XR interpolation processing to go from 60fps to 120fps. However, due to the TensorRT bug I'm experiencing, I've switched back to standard SVP for now. I'm able to increase the NGU Sharp scaler from High to Very High because standard SVP can be all done on the CPU. (To force this, Application settings > GPU acceleration > no acceleration) Note that the NGU Sharp scaler is very GPU intensive, so if you're using that, be careful when adjusting.

When doubling FPS of the test scene from here:
https://www.svp-team.com/forum/viewtopi … 509#p85509
We can see how the directly generated video of RIFE has no shake of the white lines on the right side of the screen.
But when transcoding it with SVP, every interpolated frame has different positioning of the white lines than the non-interpolated frames.
It's like you show the video normally on the non-interpolated frames and then reduce the height by a few pixels on the RIFE generated frames which makes the pixels not align with the original movie, adding a shake-like effect on the static white lines that is obvious for big screen users.

SVP devs please take a look:

Thanks!

Any possibility to make black frame insertion like vf-append or deinterlace filter that doubles the FPS? I mean what IF any other black/grey frame for motion debluring?

The OLED? The BFI still benefits for any panel types, my chinese 180Hz IPS
How to edit source script to make every other frame black? thanks!

Actually that easy to implement as I said earlier vf-append/vf-fps or deinterlace filter, without feature primary target, put black PNG over and over, devs can do that too easy, I dont use AI debugger sorry!

Is it possible to use RIFE in the JRiver media center?

Yes it will handle fps correctly, just like an filter works ontop, but instead of repeating frames, put black PNGs, no matter what display refresh rates with GSync window, since monitor will synced to output, so 72Hz with 2 black frames instead 2 repeated frames for clear motion, GSync will synced to 72 respectively!

Remember the first time you run any new video resolution with any changed RIFE version the popup comes up and cache needs to be built. Every time after that, with the same RIFE version and same resolution you previously ran, it should start immediately.

Just wanted to provide that note, as people aren't aware sometimes they just have to wait for that popup to finish its thing and not close it.

Okay, I have an RTX 3090, so I will speak from my experience with that and scale up for the 4090.

Instead of interpolation To Screen at the top, I run Movie x2, and using a program called Custom Resolution Utility (CRU) I create a custom resolution to create a 48Hz refresh rate 4K to switch to in the nVidia control panel when I want to watch a TV show or movie.

With an RTX 4090, if you can change your refresh rate to 4K 60Hz, 10bpc, RGB, full and perhaps test using To Screen, which will interpolate to 60 FPS at 60Hz, you might be able to push that, hopefully. I can't with the 3090, but perhaps that 4090 is able to do 60 FPS @ 4K, if it can't test Movie x2, and if that works properly, then crease a custom resolution with the method above using CRU.

Matching the FPS and display Refresh Rate gives a smoother experience. I had issues with VRR working properly before (flickering on OLED), so that's why I switch everything manually myself.

For the best RIFE version to use, the developer says 4.18 is the best one, but IMO the best version I have used, with the least visual anomalies, is version 4.25, which was a beta version of 4.26 (which for me is the worst).

Let me know how it goes, as I am interested in knowing the 4090 performance, if the 5090 is too expensive, I might switch to a 4090.
