Hey guys!
I have got an issue with the “automatically detect hard coded black bars” option. It won’t work when using D3D11 automatic (Native) Mode in LAV Filters. I know that it doesn’t work with DXVA2 native mode, but what about D3D11? The option works when I use copy back mode, but rendering times are getting insane then. Is there any fix for that? |

Where they struggle is poorly mastered compressed material where there is macro blocking at near black. An LCD will have exactly the same problems if they could do perfect black, LCD just masks these areas as its all just a grey mush. My OLED cant fix this, Later panels added a black crush and some extra processing to hide some of this but mine has none of this so I use MADVR, I guess you could say i'm seeing the picture as it is, warts and all. I do agree however some extra dithering patterns near black would be very useful, especially for TV rips. Some of the netflix, amazon and particularly sky stuff has been so bad over the years even though I was paying for it I sometimes had to download the episode so you I can run it through MADVR and apply some image processing. BBC are the worst offenders IMHO, there compression is horrific, Peaky blinders has been completely unwatchable at times due to streaming compression artifacts.

What do you mean with "high bit depth" - I mean, I know what that is but how does it apply here? Thanks |

If that is the solution, the panel manufacturer really ought to have a look at the problem tbh.

'Solves' is the wrong word. Effectively reduces the effect would be a better way of saying it. And sending bt.709 content as bt.2020 also effectively reduces the effect...I mean, how does that make sense, other than a processing bug in the TV? But yeah, not great for a so-called 10bit panel. Some dark content is downright ugly on this. Thank the lord madshi for madVR though!

A dithering method that would dither at 5bit or so at the black end and ramp up to output bit depth would be perfect! |

I made a video about this, otherwise it's hard to imagine what this can look like if you don't have an 2018 LG Oled. There is a ton of noise in the video because of the high ISO recording though.
https://www.youtube.com/watch?v=Sl_t3UQ3gAk And yes dithering to 5-bits completely gets rid of those flashing artifacts you see in the video. Outputting BT.2020 does too in some cases. What's funny is that most people completely negate this problem and refuse to even run the test video I made. Though the few that did got very similar results. |

also, post a clip of something that partiularly bad so we can have a look, suggest also moving this dicsussion to the general forum as its not a MADVR issue.

Yes, you must have missed it.

Both look clean on my monitor and plasma. https://drive.google.com/open?id=15H...XrjiAYo9sjxRao I've already had a panel replacement and the tech who did that knew about this problem and he also knew that a panel wouln't fix this. Though he still replaced my panel but had no explanation for this issue. |

Do remember that we're talking about madVR here, not generic OLED issues.

MadVR and color banding
Hi guys,
in those days I've compared my stand alone UHD player (Oppo UDP 203) and my htpc with MadVr. The quest is what is the best for viewing UHD HDR10 Films. My HTPC is windows 10 based (64bit), GTX970 (latest drivers), last stable madvr, MPC-HC, last LAV filters. My display is a Sony VPL-VW520ES 4K projector. My reference UHD material are the first mins of REVENANT and some other particular scenes taken from VALERIAN. Obviously MadVR is better from any point of view (detail, colors, noise, ecc.) less one ... COLOR BANDINGS! Oppo is better only under this point of view. Oppo send a HDR signal 422@12bit to my projector. Initially my GPU was setted in RGB@8bit. That's why I read (a long time ago) that MadVR natively works in RGB domain. Into MadVr I've set display=8bit Conversion to HDR > SDR with bt.2084. Debanding filter to Max dithering = ordered The image is stunning but color banding is unfortunately present. After that I've decided to put my GPU in 422@10bit output. Setted MadVr with display=10bit Conversion to HDR > SDR with bt.2084. Debanding filter to Max dithering = ordered Now MadVr reports me "window exlusive mode" =10bit In this mode the color banding effect is a little bit lower ... but Oppo is still better under this point of view. Can someone tell me if I'm missing something? Someone can help me to put my htpc to perform bandings equal to my oppo player? Thank you so much |
