madshi, can you please make a small change in switching the debanding on/off by keyboard? I've requested this around a year ago and you've answered that you will take a look at it but it might take some time. So I'm just meekly reminding about it and begging you to implement this during your current work on making the UI a bit more streamlined:

The results are consistent across everyone's display regardless of whether you see a difference or not! The better the display and the better optimised it is the more obvious the changes will be. Different displays don't invalidate screen shots at all. Might as well tell madshi to stop taking screenshots based on the above nonsense. Last edited by ryrynz; 16th December 2016 at 00:17. |

HEVC 4K, colors off in fullscreen
Hello,
why are the colors blown off (especially blue) in fullscreen with the following HEVC 4K video & MadVR? https://cloud.mail.ru/public/FsZX/4GqUibRKS (click the title to download the sample video) I'm using Sony X850C as the display (10bit & HDR & BT.2020 compatible). edit: It seems that DXVA2 image downscaling is disabled @ windowed mode, so somehow DXVA2 processing & MadVR fails at producing correct colors with this file. I'm using the latest MadVR & Lav 0.69.0 & MPC-BE 1.5 x86. The file plays fine using Windows Media Player using the default GPU decoding (GTX 960). Thanks for any help!

Missing something??
Nothing you have ticked really changes much of anything, certainly nothing you'd notice unless your using debanding or DXVA even then it's questionable. If you want full quality like I said only a few pages back, untick the lot that's what most here have done unless they have slow/dated hardware. |

About dithering
Quick questiin about dithering...
On 10-bit tv screens with full screen D3D11 exclusive mode is better without dithering? Or is it always better to use ordered dithering?

For that reason I ask. I read in a forum that with tv 10-bit panel + d3d11 in fullscreen exclusive mode disable it. What happens if I use it disabled? TV breaks or something?

If you disable dithering you are losing information like details and color transition... also dithering prevents banding that can happen even in 10bit Enviado do meu iPhone usando Tapatalk

OK after several days of testing picture quality from Blu Ray content on my KRP-500M i have come to the conclusion that NGU for chroma upscaling goes overboard with sharpness.
Picture is too messy with NGU and the resolution looks reduced. Back to NNEDI3 i have allways thought that there was too much noise in the picture with madvr compared to regular broadcast but i couldnt figure out what setting it was until some days ago it seems that i have missed two important settings with "Error Diffusion". i have allways used Error Diffusion 2 with "use color noise" and "change dither for every frame" as both of them was ticked default. unticked both of them and there goes the annoying noise that has been in the picture. if its noise now its only there because the movie has it. i must say that the picture is so good now with Blu Ray when i have found the right combination of settings that i must rewatch every movie Final settings of what i think maximizes a 9G Kuro Plasma for 1080P Blu Ray content with madvr. Chroma upscaling: NNEDI3 128 No SuperRes filter (leave it unticked) "Image upscaling" is not active here with 1080P content on a 1080P display so it doesnt matter what settings you have there. Rendering: Smooth Motion Enable (Allways) Dithering: Error Diffusion- Option 2 Untick "use colored noise" and "change dither for every frame" Thats it THE cleanest/sharpest and most neutral picture i have ever seen on this tv. Edit: 9G Kuros with Pure Drive and mostly the KRPs are sharp as hell from start so any other sharpening crap as image enhancements or upscaling refinement isnt needed. Remember 1080 lines of native motion resolution Last edited by Patrik G; 16th December 2016 at 15:17. |

Never disable dithering! Anyone who recommends disabling dithering, when using 10-bit output or not, should then be ignored for all other madVR/video playback advice because they obviously don't know what they are talking about. As CarlosCaco said you are simply losing information with dithering disabled. Ordered dithering, or even random if you want to eliminate the performance hit as much as possible, but never disabled. Disabled is only for testing.

I've been trying out various configuration alternatives. With these options I obtained the best results in the image quality. (Definition, noise, sharpness, etc.) Always in 2k to 4k upscaling. (NNEDI 256 neurons is far away for me). Another question... What is the limit on the best render time? 30, 40 ms...? Chroma upscaling NGU high Image upscaling luma NGU very high Image upscaling chroma NGU very high Crop black bars Without upscaling refinement Others option let madvr decide All trade quality for performant option diasabling Dithrring Error difusion option 1 without user colored noise and change dithering... Render time 30 ms Chroma upscaling NEDDI3 32 neurons Image upscaling luma doubling NEDDI64 quadupling 32 neurons Image upscaling chroma very high Crop black bars Without upscaling refinement Others option let madvr decide All trade quality for performant option diasabling Dithrring Error difusion option 1 without user colored noise and change dithering... Render time 29 ms Chroma upscaling NEDDI3 32 neurons Image upscaling luma doubling NEDDI128 quadupling 32 neurons Image upscaling chroma very high Crop black bars Without upscaling refinement Others option let madvr decide All trade quality for performant option diasabling Dithrring Error difusion option 1 without user colored noise and change dithering... Render time 38 ms (without dropped frames) Chroma upscaling NEDDI3 32 neurons Image upscaling luma doubling NEDDI128 quadupling 32 neurons Image upscaling chroma Let madvr decide Crop black bars Without upscaling refinement Others option let madvr decide All trade quality for performant option diasabling Dithrring Error difusion option 1 without user colored noise and change dithering... Render time 33 ms Personally, I like it with a touch of enhance detail (1.5) ... but I think they look pretty good as well. What do you think about of these screen shot?
