Chainik wrote:> Then how to make proper frame blending when RIFE_SC threshold over 15?
this is why you need a MV-based scene change detection instead of dumb image comparison
I did already, I fix this issue, tooks about 5 minutes to find out, anyway thanks!
Update : I also noticed seek performance drop, about 2x times with NVOF vectors used!

I noticed a long time ago that something was wrong, but I didn’t have time to watch movies. Versions NOT V2 and lite no jitter. I’m definitely switching to 15lite or 16lite, even if it’s x3, not x4. V2 is complete nonsense. Today I devoted half a day to tests, a lot became clear))
Picture shake happens depending on the model and fps targets, if you let RIFE profile do 60fps exact, picture shake may occur, also different TRT behave differently!
Example : 4.4v2 fixed 60 fps 25>60 (picture shake) / 4.4v2 2.5x 25>62.5 (picture shake fixed) / 4.9v2 (no picture shakes)
I have no idea if you see picture shake on 2x 3x 4x factors or something, I dont see picture shake, I use TRT 9.2 library!

I know about my 4070 capabilities, but in 4.4 too much artefacts (not critical but noticeable), secondly I dont need sync anything, GSync matches movies automatically! No magic at all!
My standard solutions for movies >
1) 4.4v2 1280x720 24>144
2) 4.9v2 1280x720 24>144
3) 4.15v2l 1280x720 24>144
Each iteration after 4.4 causes a massive performance hit @~16% for minimal artefact improvement. Above 4.9 is trained mostly on Anime.
What you say doesn't make sense to me. You say you don't use 4.4 because "too much artefacts (not critical but noticeable)", but then you are happy to force downscale all 4K and 1080p content to 1280x720p?! And you don't notice the huge degradation in quality?
I am guessing you don't have a 4K display, or else you wouldn't be saying something so seemingly bizarre 
To each their own, I guess...
Who said my monitor is 4K? I dont watch 4K at all, my monitor is standard chinese Full HD 165Hz GSync with builtin upscalers, I just test 4K source for performance, hehe! I dont see massive quality degradation only because of monitor upscalers, but my solutions shown are exclusively for 6x movie fps targets, obviously I watch 1080p with 3x for sure!

Something is wrong, because 4.16 lite working at 4K with my RTX 4070 without dropped frames
But 4.15v2 (nonlite) is very strong, I down 2160p to 1800p - works!

This type of denoisers is without quality loss...
Which one is it? The Open Intel Denoiser?
Yes, propably, I need denoiser for 720p sources, I dont prefer adjust sharpness level while watching 24>168 4.15v2lite!

Any possibility to RTX SR into mpv?

FHD or 4K?
dawkinscm wrote:RickyAstle98 wrote:You didnt understand my post, its only realtime playback bug, the models are normal, just a MPV bug, which I can fix just reencode source files! Thats because I dont give rendered example, models frame handling broken only with realtime playback! Anyway I found a fix, maybe someone facing this bug, just reencode files, voila! And how strange its sounds, I record realtime playback, and there I didnt see issue, thats why I dont give examples, even recording ontop!
So maybe I also misunderstood. I thought the video would show the artefacts but I see none. Are you saying that I have to play the clip on PC using Rife?
1) Shared video isnt test video
2) No you can play clip on anything
3) This video showing exactly how issue looks like
4) Nevermind
dawkinscm wrote:I don't see anything even after slowing it down. What am I supposed to see?
Video is predelayed for showcase purposes, this means you might see the issue as it look like, not RIFE related! Look at the car, its going reverse and forwards, thats how it looks like with newer models for me, its not rendered video!
I cant post prerendered video only because its a realtime playback bug, plz understand me! Thats propably MPV player issue, different codecs - different behavior!
dawkinscm wrote:RickyAstle98 wrote:Yes and no, because someone maybe facing my issue with 4.10+ models, for MKV (especially HEVC coded) containers, where 4.10+ models provides improper frame handling!
I mostly have AVC encoded files but I do have a couple of HEVC encoded files which I regularly use as part of my testing and I haven't seen anything obvious.
RickyAstle98 wrote:Also one more thing, yesterday I tested 4.15 lite and see one artefact, which 4.9 is properly mask! The lite models are less precise I think?
What I noticed was that I saw less artefacts with v4.15 when using TRT 9.2 than using TRT 8.5.1. Meanwhile 4.15 lite/72fps is still pretty good. I'm wondering if it is to do with the other changes I made to the scripts which I reverted back to default. I'm happy with 4.15 lite but I might do some experiments to see if I can improve it further by modding the scripts again.
Just this issue happens no matter what TRT installed, I have exactly same issue, and my friend with almost same PC build too, but reencoding some HEVC sources back AVC again, I said earlier its user related issue a bit, its only realtime playback bug, which mostly use, but not prerendered, I dont want render any movie or TV episodes, you maybe not facing this issue!

Please do elaborate.. what is the impact of this? What are my options and how does it help?
There's very little benefit in changing it. I've played with many of the options including this one and the default settings are mostly the best settings.
RickyAstle98 wrote:Insindro wrote:In your opinions, which rife model is currently the smoothest?
4.4 smoothest (for me)
For me they are all about as smooth as each other but 4.15 and 4.15 lite have by far the least artefacts. 4.15 lite is the best all round.
Yes and no, because someone maybe facing my issue with 4.10+ models, for MKV (especially HEVC coded) containers, where 4.10+ models provides improper frame handling!

Higher optimization level the longer engine build times but more accurate dynamic tactics!
Level 0 : fastest engine build/performance drop (about -2%)
Level 1 : faster engine build/performance drop (about -1%)
Level 2 : fast engine build
Level 3 : default TRT execution level
Level 4 : DONT but DONT do that plz!
Level 5 : DONT but DONT do that plz!!! (+3% performance)

LOL! Well done for finding the origin of the issue.
@Chainik can u add something from SVP side to correct/prevent/fix this blocker issue?
We don't want other SVP users to go through all the stress of trying to figure it out like Ricky just did.
I think its user related issue a bit, someone with the same GPU maybe not facing this issue, so we cant figure out what is going on?
But my friend has same GPU and almost same PC build, same issues, same problems, same errors!

Hmm, did you try these too in order to fix the frames stutters?
1. stop using Lossless Scaling on top of SVP
2. change MPV config to prevent additional frame blending like:
video-sync=audio
interpolation=no
gpu-api=d3d11
hwdec=no
3. RIFE GPU threads = 1 (in case multi threading would break the interpolated frames order)
4. frc.frame.resize to smaller resolution until your GPU has enough extra bandwidth for the worse case scenario interpolation scenarios
5. check if issue persists on v1 without performance boost (in case there are major internal differences between that and v2 with performance boost that we don't know about)
Compare it on a basic predictable panning scene like:

I found a temporary FIX for my issue, I detect RIFE prerendered video has no issues while playback, only realtime playback (even just only 24>48 hd source, easy for 4070 isnt it?) improper encoded movies MKV containers broke models frame handling, because I reencoded same video to MKV back again, and voila no issues!
