Hi, turn off artefact removal completely, you wont need this unless your material is or horrifically bad, this will make a real mess of a 1080p / 4k print, I've only ever used this once or twice ever. |

Make sure FSE is off and Direct3D is ticked in MADVR in rendering, you should also set MADVR to passthru for HDR. might also be worth a clean driver install, I think people have suggested HDR is now fixed with they latest drivers. |

you can set this up on a key to toggle off and on, set it off by default and turn it on if your clip is very bad i'd say, i'd be suprised if they were that bad though, I have an S8 and my clips are really quite good in SDR and HDR.

HD streaming rips can be quite bad I know, some movies like snowpiercer also need a bit and where this does clean up the some of the mess it cripples the overall sharpness of the image so I stand by my comments, off by default, on when you feel its required... but try and avoid it.

If you play everything well enough with the kit you have and you're not getting dropped frames perhaps just keep what you have. |

With my GTX 1080, when I try to create a custom resolution for a "23hz" mode in madvr everything works nicely except that it also automatically creates a custom "24hz" mode in the nvidia panel. Unfortunatly, it is not possible to choose 12bit with 24hz in the Nvidia panel so i have no other choice than to stay with 8bit when I want to use madvr custom resolution
Is someone know how to fix this Nvidia bug ? |

you are playing a 23,976 movie at 60 hz so this is why you are getting frame repeats. if you arent bothered about that and you are reffering to the screen going black intermittently i'm not sure, does your receiver screen or TV suggest there is a hdmi handshake loss?
if you change the renderer back to the standard instead of MADVR does it play normally? |

I think it's because of the last Intel video driver (23.20.16.4901 - Intel HD 520) but I'm not sure. All the renders works good except for madVR. |

EDIT: It works good with driver: 21.20.16.4550 (11/2016 - from windows update) 22.20.16.4718 (09/2017 - from HP) Last edited by Vegekou; 11th January 2018 at 02:55. |

They are fixed! HDR works perfectly for me now, madVR turns on HDR automatically but Windows' HDR mode doesn't turn on. Ideal.

Linear light / gamma correction for upscaling needed
Hi, madshi. madvr currently has two gamma correction problems.
Please consider adding gamma correction / "linear light" to all upscaling modes. It's really a basic thing that should be available for upscaling same as it is available for downscaling. The Jinc interpolation with the anti-ringing filter is an exceptional solution for natural-looking results with very highly reduced "aliasing" and a relatively very low amount of processing power. The problem is that in upscaling, it's largely ruined by the lack of gamma correction. For comparison, here are upscaling results with similar, catmull-rom filters: original image madvr-x2-catrom-sigmoidal-off madvr-x2-catrom-sigmoidal-on imageworsener-x2-catrom Sigmoidal light even makes the gamma-related "artifacts" worse. Currently, only NGU has gamma correction for upscaling, so I'm comparing with NGU Soft, luma doubling and chroma "very high", quadrupling disabled. madvr-x2-ngusoft This is the same effect as what happens in downscaling, but it's much more disturbing in upscaling, because...it's upscaled. Since ImageWorsener, ImageMagick, GIMP and a few other programs give better results that are similar to each other, then I guess it means madvr just has a different, more "lenient" gamma correction implementation, but it's not better nor as good. Example with downscaling: madvr-x0.5-catrom madvr-x0.5-catrom-nocorrection imageworsener-x0.5-catrom imageworsener-x0.5-catrom-nocorrection Without gamma correction, pretty much identical. With gamma correction, as mentioned above, the "artifacts" are more visible in madvr. I'll just mention that the problems are not limited to this single image. I've compared using other images, and madvr's gamma correction is always worse. I'm just using this test image because it's the best for easily showcasing the problems. I'm sure you could easily improve the gamma correction and enable it for upscaling as well, and thus make madvr not just the highest quality video renderer, but also the best video and image scaling software available. On that note, I'll just add that a custom width/height box in the screenshots menu would be very useful. Thanks. Last edited by ShyK; 11th January 2018 at 09:52. |
