Being spammed by annoying users is not exactly a great motivational help...
You have requested the feature, the developers have read it, repeating it won't get you anything. If you care so much about DV support in free tools, you should pester Dolby about releasing specifications. But of course they'll never do that, but you should try anyway!

got stuck
Hello,
I have a 4K TV and set madVR profiles correctly, but, when playing an mkv file, e.g. with a resolution of 1920x804p, I am getting incorrect source handling. madVR doesn't do any doubling, however my profiles have been set so. Additionally, after playing the first video file using madVR the player's GUI was totally mixed up (after the player finished playing the video/stopped the player manually), and when this had happened, it was needed each time to close and reopen it. I played a few hours with it and realized at the end that this issue only occurs when madVR is chosen as the renderer. The same issue has happened to me in JRiver and MPC-HC as well. So, now nothing special I would like to achieve, only wouuld like to play back my mkvs correctly using my own madVR profiles. Link to the screenshot about the problem: http://s1.toldacuccot.hu/letoltes?si...creenshot3.png Any help would be appreciated. Last edited by mparade; 28th October 2017 at 11:45. |

I don't even own a 4K screen, let alone an HDR Dolby Vision capable one. I'm not here to condone d3rd3vil behaviour or anything but... the "black box, will never happen" argument doesn't hold. In the past we've had several of these black boxes and with time they've been made usable. Wasn't DTS encoding impossible with free tools for the longest time, for instance, do I remember wrong?

Personally I have been very underwelmed with dolby vision. I have watched various DV shows via netflix on my E6 OLED and at some point I though I had issues with by panel when it turned out dolby vision was the cause.
The main issue I have seen with content using it is line bleed in the source material. Those of you who owned Plasma in the past will know what line bleed is I suspect. Well dolby vision is so great that their cameras or encoding method ends up putting that effect into the source material for you. Its really dire in some of the daredevil series I watched in the past. I steer well clear of Dolby Vision these days and I would be the first to sign a petition for TV makers to drop DV and bring back 3D. [EDIT], here is a video clip of a prime example of DV crappyness I recorded a few months back. Its not even a great quality video but you can see the linebleed over the black bricks and his chest as he gets out of bed. https://www.youtube.com/watch?v=1_ALuDz9Uo4 Last edited by Razoola; 28th October 2017 at 13:45. |

What to look for in that vid? I have seen sooo many videos about Oled faults....you have to experience it yourself. Vids usually dont help.
And Daredevil is a grainy material that certainly doesnt need DV or DV makes it even worse that could be possible yes. |

The issue the video is showing is line bleed. Look at the horizontal slat in the window on the right of picture. Then look at the black bricks at the same height to the left of it. You can see they are darker than the other bricks over the entire wall (like dark hortz line painted on them). Then as he moves up out of bed that line bleed causes he chest to have a yellow smudgy line over it. Please don't even think about saying its a lighting shadow in the room when filming took place.

Upscaling grain/noise doesn't work particularly well, which means it doesn't really benefit from upscaling. But it doesn't really hurt much, either. Upscaling helps *A LOT* for reproducing any kind of edges much better than displaying the images untouched. Quote:
http://www.avsforum.com/forum/24-dig...l#post54983374 These are from one of the best UHD Blu-Rays (in terms of detail and resolution) we have so far, and madVR's 1080p -> UHD upscale gets remarkably close to the UHD image, when talking about edges. Of course madVR can't invent texture detail which isn't there in the 1080p image. But edges upscaled to 4K look *so* much better than when displaying the 1080p image untouched. It works just fine, using the latest Nvidia or AMD GPUs, as long as you use a "good" GPU driver version. Quote:

http://www.thesycon.de/eng/latency_check.shtml I had these issues (plus occasional blue screens) on my rather old HTPC when I allowed the HTPC to dynamically clock the CPU down. Fixing the CPU at normal clocks all the time solved the issue for me. Quote:

Which issue are you talking about? Not doubling? Or mixed up GUI? |

Note that as of the Fall Creators update, Game mode is opt-in on a per-application basis - it's no longer a global toggle. Of course, if a game does opt in, it'll probably hog all the system resources.

and NN (not that i want to use it) is no real option in madVR anymore you can trigger it with an hot key but that's it. pixdelart is not important anyway it is just something that is hard to scale with a normal scaler or without changing the creators intend. Quote:
i even go as far and say upscaling an not optimal DVD source is usually showing some major problem yes edges get usually smoother but images are more than this. most scaler make the image unsharp and sharpening i shows other issues. yes you can change the upscalier for different image types Quote:

To me Mike and madshi are the same level of experts, they don't need Dolby to run their business. |

But i reverted to windows 8.1 and everything is great again. (Not great because since XP there is no best windows os). Im not sure what happened because before fall creators update evrything was just fine with default FSE in d3d9. I could have reverted to windows 10 before Fall creators but everything in windows 10 make me sick. The main problem is the pain we have in selecting the updates we want or not. And other bugs. And the privacy probems. I need more time to configure everything in windows 10 than to actually install it. I will wait for windows 11 (If "11" is a number they think its not bad luck). What a crap company microsoft become. Microsoft keeps trying to impose new "sh/%#/T" to us without care what we all want. Cant they see we prefer simple things to anoying 3d windows coming from everywhere and notifications flying around even after i disabled EVERY NOTIFICATION. THEY KEEP APPEARiNG. sry for venting -.- Last edited by xabregas; 28th October 2017 at 17:55. |

Now it's a valid question if NGU AA is able to "interpret" the images in such a way that brings them nearer to the original image creator's intent or farther away. This is a topic that would probably be valid grounds for heated discussions. Personally, when re-playing old pixeart adventure games, I'd much rather have NGU AA upscaled images than nearest neighbor. But I suppose every user has a right to decide for himself. Generally saying that upscaling pixart with NGU AA does not honor the image creator's intent is IMHO not fair, at least I don't agree with that. Quote:
FWIW, DVD sources are not even encoded in their native aspect ratio, so it's impossible to display DVDs without scaling them in at least one direction! Quote:
That said, with 385.xx drivers it might have worked ok. |

madVR v0.92.8 released
http://madshi.net/madVR.zip Code:
* added 3 new "reduce compression artifacts" strength steps between 1-4 * removed deblock option "don't reduce texture detail", wasn't useful * replaced old "reduce random noise" strengths 1+2 with a new strength 1 * fixed: key for increasing "reduce random noise" strength stopped at 5 |
