Ya, forgot to mention that I notice microstutters with the 4.7 model. This plus the fact that it does not improve artifacts in any meaningful way led me to stick to 4.6.
I've always had micro stutters because I'm watching in VR over wifi which increases latency. As for artefacts, maybe we are watching different content because at least 1 major artefact is gone and I see improvement with the minor ones too. The best example is in Gravity at around 16 minutes when the astronaut is floating in space. With 4.6 the whole background is shimmering. With 4.7 the shimmering is gone.

If I want it to be smooth all the time, I need it at 15%.
But then the scene changes are really bad.
MAG79 wrote:> Another thing is, the current RIFE Scene change detection
You can adjust it manually the same way. Find and change value of setting rife_sc of profile RIFE AI engine.
I've done that but it doesn't help because whatever number you set causes issues with Rife. Set it one way and it fixes certain issues like double imaging but then freezes on scene changes. Set it another way to stop the scene detection freezing but then certain scenes have double images. Even if I manually set it differently for each show I still end up with the same issues. Rife is the best for smooth playback and usually with less artefacts. But it's artefacts and issues when they do occur are much worse than non Rife solutions.

I just tried the latest update(was about 20 hours ago at the time of me writing this), and it seems version 4.7 is slightly easier to run now. It's still harder than 4.6, but from the small bit of testing I was able to do for now, it seems slightly better. Hopefully it gets some more optimizations to make it about the same as 4.6
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.

L.E.: Never mind, I renamed 4.7 to 4.4 and seems to be working now.
Cool! Did it create cache entries or are you still using the original cache entries that were generated by 4.4?
It created new cache entries indeed. However, I don't really see any improvements in regards to artifacts. Fast-moving objects against more complex backgrounds still show mostly the same contour artifacts. Not sure if replacing the 4.4 model and renaming 4.7 works properly.
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.

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.

mmm.... replace rife_v4.4.onnx with rife_v4.7.onnx?
So obvious but I never thought of doing it that way. But if it works then cool

DragonicPrime wrote:This version seems to run worse than 4.6 for me. GPU usage is higher. It doesn't seem to be much higher, but it's noticeable
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.
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.
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.

Wow, you are the dev for this and clearly by your answer you have no intention to improve it so i'll just use something else. what a bad attitude to have and misleading people by saying that SVP is updated regularly
What do you think needs to be updated? What features would you like to see?
Blackfyre wrote:Any progress at all with Dolby Vision and RIFE working correctly? Are there any updates to look forward to or being tested in beta?
EDIT:
Can @Chainik please update MPV to v0.36.0 from July, the installer says it is currently using v0.35.1 from January.
If you are on Windows then download the latest mpv executables "mpv.exe and mpv.com" and add them to c:\Program Files(x86)\SVP\mpv64 replacing the ones that are already there. But tbh unless you are looking for something specific in the latest build, I don't think you will notice any difference.

Oh ya I'm aware of the artifacts, especially on fast moving objects and camera pans. I thought you were talking about Ensemble at 4K, as many people reported artifacts that only occur in 4K mode, but I can't test that since my TV is 1080p. Hopefully they can fix most of these problems with a new Rife version. I'm surprised that we haven't received a new version with how fast devs release text to image generation models these days. I know it's not the same thing, but Rife 4.6 is almost 1 year old... was hoping to see a new version integrating some deblur tech too by now.
Rife is mostly great but some of artefacts are worse than Automatic. Turning up the Scene change threshold helps. The major artefacts are still there unchanged, but the lesser artefacts almost disappear completely. I had it at 15% but it sometimes causes noticeable artefacts at scene transitions. So far 12% seems to be about right on Nvidia cards.
It looks like it's telling you that you can only have a maximum of 2 GPU threads.

Not something I even knew about to be honest. I have a similar setup to you and I was only interested in Ensemble which I have now tested and confirmed that it did make existing Rife artefacts worse.
Ah I see. I haven't tested Ensemble cuz I haven't yet got a 4K screen (minght get a QD-OLED next year, since the 2023 Samsung ones still have some problems). Waiting for a new Rife version, hope it comes out soon. Also, hope UHD sees this comment and reaches out with some instructions to test the deblur model 
You don't need any particular resolution see the artefacts with software interpolation. Rife mostly has much less of them but the few I have seen tend to more obvious. With whatever benefit Rife Ensemble might provide, those same Rife artefacts are made even worse.

I've never been sure what that meant lol. The movies I watch are 24hz 1920x2160p (2x1080p) -> 60fps and with Rife it is very smooth. There is the occasional judder but's more to do with my setup than Rife. But as I said, I was hopping that what I saw previously when I tested Ensemble was a performance issue. But instead it really does make Rife artefacts look worse.
So I tried Rife Ensemble before and whatever artefacts Rife has, it had the same but much worse. i was hoping that it was maybe a performance issue. But now I am able to properly test it and it exactly like before. It has the same issues as Rife (with white on black like star fields or chequered patterns) but unfortunately they do look much worse. So back to Rife 4.6.

I'm getting a new desktop setup with an i7-13700K and RTX 4080 next week, so I can test by then.
What happened with this? Are you using it for Rife? Have you tried Ensemble?
I'm currently using a 3080 10GB and it works well with Rife 4.6 but not Ensemble. I would like to know if anyone with an RTX 40 series card has been able to get Ensemble working?

Solution to... what? It works pretty nicely, the V2 just doesn't work well at 4k but V1 is fine.
I remember saying I had no issues at 1080p with v2 and that is correct. But it seems that the quality drops at (maybe) any resolution above 1080p, not just 4k.
They don't need to update it. You can replace the existing binary with the new one. If you don't know how then it doesn't matter because there doesn't seem to be any major benefit of updating it from what I can see.
Sorted. Not an SVP issue.
