Your impression is not enough. From what I see, Madshi reads scientific reviews to learn about new algorithms and progress in image improvment. When he makes a decision, there's a big chance it is the good one.
Don't forget the best image is not what you like the most, but the one which looks like the original the most. So we'll have to do ala Hydrogenaudio dictatorship: you need to provide proofs from your analyse with screenshots like this post for example. Madshi said he won't add option for one guy, so you have to convince him ! |

All these heuristics like downscaling an image and upscaling it again with different algorithms to see which is closest to the original, are just that, heuristics. They are useful for comparing algorithms, or even designing new ones, but they're no substitute for actually looking yourself. |

madshi, please add an option to DISABLE chroma doubling for those who don't want/need it in the drop-down list. I can run VeryHigh NGU, but the chroma doubling seems useless, even with the Normal (Bicubic 60) option. I'd just like to disable the chroma doubling altogether.
I'm going back to Jinc SR4 for Chroma and Upscaling. Looks just as good and has very low render times (15ms) Last edited by AngelGraves13; 10th December 2016 at 05:49. |

Nice example i guess everyone can percept the shaprness difference here like in Neo-XP his examples with NGU-Med Your example becomes even more fascinating because of the lower filesize of the better perceptable psy result. I mean we talking in your example about almost 10kb less for this particular frame with a overall better psy result. But this was allready visible in Neo-XP his examples though not really with a final filesize reduction but the opposite. So your example is kinda also crazy in it's overall result there seems to be a compression benefit as well now ?. We definitely need some better more scientific analysis of what madshi does here

more red on black comparison.
bicubic 60 AR: https://abload.de/img/bicubic60arq0ltz.png bilateral sharp:https://abload.de/img/bilateralsharpuza5g.png NGU low: https://abload.de/img/ngulowwbzq1.png NGU very high: https://abload.de/img/nguveryhighqglpe.png recon sharp: https://abload.de/img/reconstructionsharprjbmr.png super XBR 100 AR: https://abload.de/img/superxbr100ar43a0c.png super XBR 150 AR: https://abload.de/img/superxbr150arkra6a.png super XBR 150 AR is doing an fantastic job for it's price on this image and bilateral is doing pretty bad here and that is the most obvious thing to "learn" here. @StinDaWg i'm pretty sure he got your point. but the chroma scaler aren't there to waste electricity. people created these scaler and put a lot of work in them and they are not joking around. if you don't see the difference FINE! but why do you have to stop them comparing chroma scaler? @khanmein nothing changed for madVR usages so whatever: http://bugs.madshi.net/view.php?id=431 |

NGU doubling is really impressive with 720p animation @ 1080p. After playing back an episode of Family Guy in 720p and then 1080p version, it was hard to tell the difference. It's easy to tell the difference with Jinc and NNEDI3, 720p version looks blurry. Switch to NGU and bam, back in focus. The only thing that stands out is aliasing on some diagonal lines with NGU, otherwise they look almost identical.

But, if the only way to tell the difference is with these extreme fringe examples, then more power to them. That will be my last comment on the matter. It really doesn't matter to me what other people use. I'm just glad something like madVR exists for us videophiles. Last edited by StinDaWg; 10th December 2016 at 13:54. |

Super-xbr is much more polyvalent, with values of 100-150. I use NGU-Med at the moment (or NGU-High on new versions), because it is overall sharper and cleaner... and it is cold now where I live Example with BilateralSharp / Bicubic60 AR / super-xbr150 / NGU-Low / NGU-Med / NGU-High : I zoom for you in the right spot : Now I let you decide which one to use.

try to compare bilateral and super XBR 150.
most obviously the red triangles but not limited to them. i don't think it is possible to hide the differences with a sub sampling screen. maybe vivid mode or something like that can hide this but... i'm pretty sure firefox can't hide this what so ever. this is not a chroma heavy image but it still shows a huge difference with bilateral. |

OK. I see a slight difference in sharpness/clarity with the red triangles between bilateral and super XBR 150. Less so with bicubic 60AR. If that's all I'm missing by using a faster algorithm, I'm fine with that. There's no way I could see that in motion anyways.

Hello, I seem to be having some weird performance behaviour with NGU.
In one case madVR v0.91.3 NGU very high was taking 90 ms, but if I switch to NNEDI > Nearest > NGU very high it goes down to 16 ms for a dozen seconds and then back to 90 ms.: https://www.youtube.com/watch?v=Vt8FdGAgXL0 On madVR v0.91.4 similar situation has occurred on a different video. Using NGU high I watched few episodes with 30 ms / frame performance, but then it suddenly went up to 175 ms / frame. I tried previous trick and it went down to 40 ms / frame. While I was writing this post it has managed to go back to 30 ms / frame.: https://www.youtube.com/watch?v=tRxcFWl4qfA Edit: it refuses to play at 30 ms / frame anymore. Had to revert back to NNEDI to continue watching. Edit2: one episode later NGU works properly again. Edit3: I think I figured it out. My GPU goes to sleep for some reason and reduces performance to save power and lower temperature. Any idea how to prevent this? Not sure whether this is madVR issue or something with my system, but this never happened back when I was using NNEDI. I have GeForce GTX 1070 with driver version 376.19.
