New RIFE filter - 3x faster AI interpolation possible in SVP!!! (Page 35 of 85)

The good news is that a recent git update suggests that Rife 4.7 might be coming although I can't find any timescales to suggest how quickly that will happen. The bad news for me is that it's focussed on improving anime.

Thank you very much for this

After some testing it looks like the artefacts have been reduced in this model. The star field in Gravity no longer shimmers.  The intro to Blade Runner 2023 where they fly over tiles used to shimmer a lot, but now it only shimmers a little when the ship flies over. Need to do more testing but this is an obvious improvement over 4.6.

My GPU usage is all over the place which is probably my fault. But overall it is measurably higher than before. I know where to look for particular artefacts and they are all less prominent in 4.7 than in 4.6. One major artefact has completely gone. This was my main issue with RIFE so the higher GPU usage is worth it for me.

I run SVP with 1920x2160 files. With 4.7 GPU utilisation averages about 75%. With 4.6 the average was around 53%. That's a pretty big jump which as I said I'm fine with. But I do wonder if there is any optimisation that is still to be done or is the new model simply more dense with information so it is what it is?

@Chainik: Maybe worth adding 4.7 to SVP too? If not... how do I add it manually ?

So obvious but I never thought of doing it that way. But if it works then cool

Did some more testing. Rife is obviously smooth with 4.7 in particular removing or reducing some of the more egregious artefacts. But when it does have artefacts they still tend to look worse than when on Automatic. One particular vertical fast motion scene sees the character drop down to the ground. With Rife, the character seems to disappear every other frame so the character is flashing. I compared this with automatic and this doesn't happen. I use Rife by default but I do wonder if Automatic should be my default instead.

Cool! Did it create cache entries or are you still using the original cache entries that were generated by 4.4?

I see improvements with fast moving objects and also chequered objects. So less artefacts than 4.6. However the few remaining artefacts are worse than Automatic which is the same as 4.6.

Dolby Vision now works in:
1. mpv
2. MPC + Avisynth Filter + MPC Video Renderer
3. MPC + Vapoursynth Filter + MPC Video Renderer

BTW just pushed another update fixing DoVi blinking in mpv or Vapoursynth Filter.

RIFE will blink with DoVi content, dunno how to fix this.
Problem is DoVi often change colors right in the middle of the scene. So if we have interpolated frame here made of two adjacent frames with _different_ colors, it will visually blink.
So the only option for RIFE I can see now is repeat one frame at these points. Meaning, turn off interpolation in the middle of panning scene, for example, maybe several times.

It might be to do with the upgrade of mpv to the latest version. But I've been using the latest version for a few of months now so it made zero difference for me.

I get occasional but predictable micro stutters. The kind I probably wouldn't notice on a smaller screen like a TV. Yesterday, the mpv source was updated with a few nano-second timing updates (including vsync) that I thought might make a difference. With the new build the micro stutters are now nano stutters. The difference is subtle and may be placebo but it seems to be repeatable.
