So I think this is actually an SVP fix for image scaling rather than a Nvidia/Microsoft fix. I mentioned previously that I had issues with Dr Strange 2 but that's because it was 3D SBS and for whatever reason SVP did not handle it correctly. But since the latest updates, it is handled in the same way as files of the same resolution in other 3D and non 3D formats.  Correct scaling is responsible for the improvement I see with my GPU, not Nvidia/Microsoft.

Guys, do I need to disable hwdec=auto-copy in config? MPV got updated and it reset my config file.

Actually no, auto-copy better for RIFE procedures, for me for example (RTX 4070 user)

I remember @chainik saying that this is no longer the case and after testing it looks like we don't need to specifically use *-copy anymore.

Scene change 100% allows rife to interpolate everything all the time.
Scene change at 99% and below enables the selected scene change detector to compare the frames
if a scene change is detected then it will prevent the interpolation by repeating the same frame and creating a "microstutter" in order to prevent visual issues that happen when camera teleports around.

Ahh yes that's it, it turns off SC not Rife. It was late and I was tired lol. 15% works really well and I remember saying the before the update, 15% and above behaved the same for me. But SVP has been updated and I see that 25% behaves a little differently to 15%, so I will give 99% and 100% a try.

Doesn't setting SC to high figures like 99% majorly reduce how much interpolation is being done? Doesn't setting it to 100% effectively turn it off. Isn't that what we were doing previously?

Edit: 100% turns off SC not Rife.

SVP Motion Vectors in those specific time stamps makes the creature ribbons and America Chavez look as though they are dropping frames (even though there are no dropped frames at all), similar to Image Comparison when its set to very low percentages like 6% for example. But with custom 99% it is the smoothest always.

That's like what I was seeing in Alita at certain scene changes where she was skating.

There's also scene in Dr Strange 2 where using SVP to reduce screen size actually helps to remove a movement artefact. The scene when he throws his cloak towards the monster to rescue the girl, there's always a little judder and some artefacts when she returns. But with Decrease Screen size, it's gone.


Same with the cloak and the bike for me that scene its horrible mismatching.

Apologies this one was my mistake. Yes those scenes have always caused me issues but not with v4.15 or v4.18. I was in the middle of testing GPU vs CPU using v4.9 for comparison and forgot to change back to v4.15/18. With v4.15/18 those scenes work fine. However the reduction in GPU usage and moderate increase in CPU is still there. BTW There's another movie scene I recently added for testing which had artefacts even on v4.15, but with this recent SVP update they are gone.

*deleted*

Something interesting is happening. Before in order to reduce GPU usage for my 1920x2160p movies I had to reduce screen size using SVP, even though my screen was set to 1080p. I no longer need to do this. There was another related issue with a 3D SBS file that didn't work properly which now works fine.  This means that I have now regained control over the downscale rather than relying on Vapoursynth downscalers. I thought maybe that Rife wasn't working because there is a bug in SVP where it sometimes runs but is not actually interpolating. But the test scenes are smooth and my GPU is running under 40%. But CPU load doubles when in use so maybe more of the load has been handed off to it.

New Rife 4.18 here:
Interested for those who do tests to see if there are visual improvements with 4.18

Thank you. I was not expecting this. Anyway I did a quick run through my test scenes and was about to give when when I did find one scene which had a minor improvement with reduced movement artefacts to the point where you almost can't see it anymore. That's a good sign of hopefully more good things to come.

Thanks again smile

meaning
1. it's a false positive SC, right? in which case you'd better share a sample with the problem... there're a lot of variables to adjust there.
2. you really prefer "RIFE-generated "garbage" frames" over frame repeating at a false-positive SC big_smile

No! I prefer a smooth 60fps motion where an action is clear without jitter or stutters. That's why I paid for SVP, but apparently I was mistaken. Good to know.

Chainik wrote:

probably you just prefer RIFE-generated "garbage" frames over repeated or blended ones

By the nature of your response, I'm guessing by your comment that SVP motion is your baby and because of that maybe you are missing the point. I want SVP motion to be better.  All I'm trying to do here is provide feedback to help you make it so.

Anyway, I tested using an MPV build from this week with the latest SVP update. Maybe it's the latest mpv build or the MPV changes you made,  but SVP motion has improved since the previous update. But since I'm almost certainly watching on the largest screen here, I can see stutters and micro-stutters thats most may not. SVP motion has at least a couple of clear and repeatable stutters for certain scenes that IC does not. Other than that, IC at 15% and SVP motion are practically identical. YMMV.

In all my tests of problem scenes, SVP algorithm at it's best can be better than Image Comparison, but at it's worst can give artefacts similar to NVOF. Image Comparison seems to be the best compromise giving the cleanest output with the least artefacts.

Chainik wrote:

Drakko01

>I still think that image comparison work the best

to be "the best" it must give less false positive scene changes, and less missed scene changes
which is not true

Prior to this latest update, the SVP algorithm might provide the best objective test results for false positives etc, just like a scaling algorithm might have the best objective PSNR and SSIM image quality scores. But in both cases, the resulting output when viewed by a human being can be less preferable to a lower scoring algorithm. It has it's faults, but Image Comparison just performs better overall for every problem scene I have.

*Edit. This conclusion is prior to the more recent SVP update so I have updated comment. Actual test updates will follow.

I think the previous comments are proof that this is setup dependant. SVP MV works best for @Chainik and works well overall but also has clear micro stutters. Some of the stutters are not so "micro". NVOF has always had clear stutters for me but works well for some. All except NVOF are siimlar, including Disable. But for me Image Comparison seems to work best with no obvious microstutters.

the default one! (which is "SVP motion vectors")

The default one works well with everything except the intro to Hugo where it stutters considerably.

Installed the latest update and I noticed the Duplicate Frame Removal drop-down switched to Remove Every Other Frame. Shouldn't this stay on Don't Remove, even with Image Comparison + SCT 100% + Blend Adjacent Frames?

Mine didn't do that but did anyone else's do that?

The only bug I've seen is that sometimes when you change the Decreasing filter then SVP doesn't work the next time you start a video. But if I make sure to exit the Frame Size window back to the Main window then SVP always works with no issues.

NVOP was the worse in previous testing and nothing has changed.

Idk how you test, everything works as intended, check my previous comment, everything over 15/25% is similiar to look!

I know everything over 15/25% is similar. Actually I was the first one to point out that everything over 15% is similar smile But that's what I found worked best with version of MPV that comes with SVP. I've done more testing and found that my later version behaves as before which is a little different to MPV v0.36.
With 0.37 I find that 15% is the smoothest of should mean anything 15 and above but that's not the MPV that comes with SVP so I didn't update my results.

I test with a lot of different types of movement and  I've been using the same test scenes for maybe a year or more so I am very familiar with the artefacts being generated by Rife or in this case by SCT. I also watch on a very large screen so I am able to see every microstutter and even the smallest artefacts.

In the end all of this stuff is setup dependant and YMMV smile

SVP 4.6.0.272

1. added motion vectors-based scene change detection for RIFE
2. configurable "decrease to..." function (on the "Frame size" page) - selectable target resolution and downscaling filter

Thanks for the update. I decided to completely reinstall everything to remove any changes I made. The results so far are that
- SVOP and Image Comparison and disabled give very similar results.
- NVOF might be a little worse overall but still similar.
- This is the same as before except that all of them feel a little less smooth than the previous setup with SC set to 100.
- Setting SC to 100 with this new software seems to be similar to the others as well. Although when I add back the MVP interpolation code that helps. I also put back the TensorRT9.2 files.

Let's see what others say.

I think with microstuttering, some of us can see it because of a large screen size or we are sitting close to a TV or maybe some of us are more sensitive to it. But I think we all get microstuttering with Rife.

I noticed that if i exit specific background apps like TeamViewer, i suddenly get 20-30 extra fps with SVP.
I believe TeamViewer reads the memory and causes a bottleneck even when it's minimized in taskbar.

Xenocyde try to close your 200 Chrome tabs and other background apps and see if u find the specific app that causes that microstuttering. It's good to know.
Try it with the 4.17 lite version cause it's easier on the GPU:
https://github.com/AmusementClub/vs-mlr … nal-models

The v4.17 lite version is an experiment and from what I see, it's worse than even v4.17.

I just want to get to the bottom of this. Was not my intent to call you a liar, I was asking for the exact options you have there because I think having Power management Mode on Normal might cause more microstutters, I'm currently testing with Prefer Maximum Power.

OK, I made those two modifications with NVCleanstall, but I can still see 2-3 stutters per 40+ minute TV series episode. I don't have 3D options on default as some games require certain tweaks. Also, I don't really think it's possible you left everything on default, but whatever, maybe I'm asking too much.

I told you about those two changes which I don't think I've ever mentioned before. I also told you that they were unlikely to make any difference, and your response is:

No changes made to NV3D panel.
I've made some (very) low level driver tweaks by disabling Multiplane Overlay and enabling Message Signalled Interrupts but I doubt they would make a huge difference.

Can you please show a pic with all the options in the 3D panel and maybe explain how to do the other two things you mentioned?
