Re: New RIFE filter - 3x faster AI interpolation possible in SVP!!!

I'm not sure about that. In all my test scenes RIFE is both smoother and has less artifacts than normal SVP:

Top 3 (quality/usability)

1) LSFG (better than SVP algorithm, smoother, accurate, same resources)/(usability priority)
2) RIFE (better than both, smoother than SVP algo, but 8 times heavy)/(quality priority)
3) SVP (same resources as LSFG algo, lightweight)

I found this panning scene useful for smooth tests:

They just updated latest RIFE model to fix "abnormal artifacts" https://github.com/AmusementClub/vs-mlrt/issues/155 :

Now we can finally upgrade the RIFE model after more than a year.

I hope so because while RIFE is still the smoothest the few remaining artifacts were horrible. In my testing I was able to remove every RIFE 25/26 artifact from all my test scenes using SVP. But if the new 26 heavy can remove those artifacts too then I'm there. I'm still impressed with what SVP can achieve though and if the new 26 heavy isn't that much better then I have no issue using SVP with LSFG smile

Re: New RIFE filter - 3x faster AI interpolation possible in SVP!!!

So the new 26 Heavy is better than the old 26 Large and is the best RIFE released. It fixes some artifacts cleanly like:
Alita Battle Angel 1:33:26

It improves the Occlusion issues at:
Alita Battle Angle: 1:34:50

But it still struggles with fast vertical motion. The artifacts shown below can be reduced but not fixed by using Image Comparison at 6% just like previous RIFE 25/26 versions. A 4080 can handle this so maybe a 5070ti can too. The last two examples are bad and look very ugly:
Alita Battle Angel 1:34:57
Amazing Spiderman 1:52:49
Man of Steel 1:46:37

I can get almost identical smoothness and less artifacts by using just SVP. With the exception of the PEL override for Quarter Pixel accuracy, the settings I use are a modification of SVP Automatic with the Quality Slider fully moved to the right.  Below are the baseline settings that work well. You can modify them depending on your GPU, but beyond a certain point up or down you may make things worse again so YMMV. 

Edit: Motion Vector Grid 24px works best for the Man of Steel artifacts at the above-mentioned timestamp.

With the scenes I using to test with, I can run 120fps with almost no artifacts. If Rife 27 comes along with even less artifacts then I might switch back to it because the motion is a little smoother and a little clearer. But not by much.
