Great quality debanding, faster perfomance than MadVR
Deband (originally in mpv in glsl syntax) works much faster than MadVR's debanding and can be used in any player (only in EVR-CP render at least now)
How it works Download deband shaders https://vk.com/doc275347426_493873949 Hlsl deband/MadVR (default/low-dxva-billinear settings except high deband) By the way, I can not get what noise gives. In descriptions it says #define Grain 48.0 //[0.0:4096.0] //-Add some extra noise to the image. This significantly helps cover up remaining quantization artifacts. Higher numbers add more noise. (Default 48) But I do not see any 'significant' differences with/without default random noise. It slightly improves GPU load, so I do not use it. Can you give examples, when this noise is useful?

If you're not watching a movie with HDR, you can use FFDShow to call f3kdb in the avisynth section of ffdshow, or some other deband filter.

Also what settings did you use for madVR? You seem to have left out all the details on how you did the comparison and a link to your source.

I have no experience with this player.
I use MPC-HC, primarily. VLC as a backup. With FFDShow, don't forget to check "Add FFDShow Video Source" in the avisynth section. I know SVP can use the GPU, if it's detectable. I use SVP on my graphics card all the time and only switch to CPU for testing (if graphics card not working well).

Are those the same image? Any information at all about the settings used?
You are only posting examples without any detail, how well does reshade's debanding persevere detail compared to madVR? How about compared to madVR's remove compression artifacts?

Bad side? They exist. Reshade is not native solution, but it can be (if somebody port shader to usual hlsl), it's not friendly with SVP (60fps) - player info sas it has less frames (not dropped frames), it has little frames tremor and also some not critical problem when playing serials - you need to stop, not pause, playing and start to play again between two files - switching do not works okay. But anyway it is better than madvr 'highest' deband settings. I will attach images later |

I don't agree, NGU for 1080p @ 4K is very nice. I suppose good chroma upscaling for 4K is not that important but I do notice an improvement using NGU AA v.s Jinc or bicubic.
Most of my content does not have bad banding (Blu-ray) but madVR highest already blurs too much for me. Is this less blurry or the same while removing more banding or is it simply stronger?

*I mean, reshade's deband much better not only because it 'better quality', I can accept a little worse quality of MadVR, but also MadVR has much more worse perfomance on high settings, which is visible if I use highest settings
There is comparison, madvr left and reshade right, you need zoom to watch it better. In the bottom you can see size of MadVR and Reshade picture, coz reshade's gradients are smoother, picture has a little bigger size and can not compress so good. -_- potplayer could not copy well, need to reupload Last edited by Dreamject; 8th February 2019 at 00:17. |

Reshade settings, it's not only 'low middle highest'
Also, it could not replace madvr, but can be added as hlsl pixel shader, but now people do not think a lot about (de)banding, developers who can port do not see reason. Even MadVR is well famous mostly for 'geeks' and people do not like a lot of settings. 'MadVR is best quality render, it uses best debanding, it request a lot of resources'... But actually at least debanding does not need so much as MadVR+only debanding need. PS If you need less strength, with 'reshade'-like deband you could reduce therehold and sensivity for yourself, not just touching low-middle-high setting Reshade vs default without madvr Last edited by Dreamject; 8th February 2019 at 00:24. |

I can see banding even on bluray at least I know some of them. Banding is not 'main' reason of low bitrate, I think it is compression artifact and reques postprocessing even on bluray, but on lower settings. For ~bdrip quality and not very smart computer reshade-like shader is much more better because of perfomance and strength, for smart pc+bdremux it's still can be better because of more precise setting Last edited by Dreamject; 8th February 2019 at 00:34. |

Do you have the movie Rush on Blu-ray? The opening credits have terrible 8-bit banding. I used it as a comparison in this thread:
https://forum.doom9.org/showthread.p...76#post1840876 I thought madVR did a fine job here.
