Forgive me if this has been discussed.
How would I go about creating a 3dlut for 4K HDR videos, that would take advantage of my SDR television's (panny st60) native color gamut? I have a colorimeter/spectro/calman and have played around with it some, but i can't figure out what the correct way to do this would be. Any ideas? |

I have used DisplayCal in the past for 3dluts, but it seems to have trouble with nailing down near-blacks on a plasma. Calman does a better job, i am just not entirely sure how this all needs to be configured to get a 3dlut that will take advantage of the extended gamut for HDR videos.

i don't know if calman supports a HDR -> SDR conversation 3D LUt.
madVR support both HDR -SDR 3D LUT and HDR-> HDR 3D LUt's. but what i know is selecting a different target is not enough. edit: well you could create a SDR bt 2020 3d lut and run this but madVR can do better HDR->SDR 3DLUT. Last edited by huhn; 18th October 2017 at 08:51. |

Here's my results with several drivers on Win 1709 with an 1050Ti card: 378.92-desktop-win10-64bit-international-whql No HDR option in windows, unusable. 382.33-desktop-win10-64bit-international-whql Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace 384.76-desktop-win10-64bit-international-whql Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace 385.41-desktop-win10-64bit-international-whql Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace 387.92-desktop-win10-64bit-international-rs3-whql HDR doesn't turn OFF after video stop, but this is the only driver that gives me good colors. Unfortunately unusable because it doesn't switch HDR ON/OFF properly. So i'm sticking with 385.41 for now As a sidenote: After installing the 1709 update, my desktop colors were really dark. I got this solved by running Display Color Calibration. Last edited by HomeY_; 18th October 2017 at 11:38. |

- Try reducing your decode ('CPU') queue too. When using DXVA Native, the decode queue is kept in graphics RAM, so setting it lower could help. Hardware decoding on the Pascal cards is so fast that you don't really need a very high decode queue anyway, it fills up nearly instantly. Try something like 10. - Close all other programs when playing a movie. Any open program uses video RAM for its application windows textures. - If it still doesn't work, try this with DXVA Native: Present queue 4, Render queue 6, Decode queue 8. - Did you try Windowed mode? It works quite well on my 1050 Ti on Windows 10. (Edit) - Probably not linked to your issue, but I see you have not enabled VP9 hardware decoding. Is there a reason for this? Your 1050 can decode VP9. Quote:

You change color in Resolution tab? I wonder if none of you had trouble trying to switch from RGB to Ycbcr before? I needed to do some weird rituals for the drivers to assume RGB FULL color. Restarting OS. Changing other options in Nvidia Control Panel. And as i never trust this driver i always check if RGB Full is selected on my Nvidia Control Panel before i watch a movie. I remember AMD was worst. My tip is if you get a driver that works wonderful for what u do daily u should avoid any updates. And as for windows 10 updates i have it turned off by default on services.msc. When i remember i turn on. See the info about the update and Update or not. Then OFF again. It depends. Dolby Digital Plus from amazon prime streams is awfull and very badly mixed most of the times. Last edited by xabregas; 18th October 2017 at 15:26. |

Hopefully someone can help
Following: HTPC running Kodi 17.4 DSPlayer + madVR Intel i3 Nvidia GT 1030 4GB RAM Connected to Denon AVR X1200 Beamer Acer M550 4K HDR connected to Denon Used HDMI cables are fine and support all i need I can set 4k resolution in NVCC 60Hz but only RGB Full @8Bit HEVC Playback works fine but HDR seems very dark Beamer is switching to 4K 60Hz and recognize HDR automatically I can stop a video file and start another one without issues. I can also set 1080p 60Hz RGB Full with 12Bit in NVCC I can play one HEVC 4K HDR file Beamer is switching to 4K 60Hz and recognize HDR automatically I can stop the file but i can't play another one If i start another file Beamer is Switching to 4K 60Hz HDR, but i get back on the desktop and there is just a black square about 25% over my desktop. Have to kill Kodi with Taskmanager. It seems there is a problem while switching the resolution after playing one file. I also played around with exclusive full screen, but that did not help. Is there a resolution for dark HDR image quality if Desktop is set to 4k resolution? Is there a way to fix the second playback issue for 4K files if desktop resolution is set to 1080p? |

@madshi
These new algorithms pretty darn good for image processing: http://screenshotcomparison.com/comparison/121039 http://screenshotcomparison.com/comparison/121038 http://screenshotcomparison.com/comparison/121040 I think you should release a tool or even better a paint.net plugin for these, they're worthy of it. I couldn't get a palatable result result for these images with paint.net filters ( even including some third party plugins) Ironically I don't find them very practical for video, because even these photos took several minutes of trial and error, videos would take even longer and I'd have to optimize for ever video (or at least ones that are not related to each other). Also my GPU is not beefy enough to run these too in real time. Last edited by mzso; 19th October 2017 at 09:23. |

For strength 3-10, I prefer when this option is activated, it does help to retain some details. Strength 3 is quite debatable though... It depends if you value more perserving details or reducing compression artifacts. I switched on and off a lot of times but each time, I've found that I have a slight preference for "Don't reduce texture detail" activated in this case. Strength 11-12 is so high that this option doesn't seem to make a difference so I woudn't activated if it aims very very blocky sources and if it could misses some artifacts. It's just a guess though I don't have sources to really test these extreme strengths.

Hi madshi, unfortunately I have not conducted organized tests. But, as I mentioned initially, the higher settings on RCA and RRN make wonders on badly compressed old anime (talking about less than 100MB for 20mins episode). As such, I hope that whatever setting you'll end up making available on a permanent basis will keep really low quality sources in mind.
Thanks. Edit: also regarding Fall Windows Update... I am on Business Branch and I've opted for deferring feature updates up to 365 days. But, really, Microsoft is doing its worst nowadays to make me hate their business practices. |

Personally I feel 11 and 12 are so heavy that DRTD should be enabled, I can't imagine any scenario where having it off would be beneficial. Even with the above video being almost as bad as they come I still think the absolute limit I would ever use on that is 10, above that as resemblance of lines/objects pretty much disappear. 3 and above with DRTD has my vote. |

Yeah, think that's what I've been seeing. I have my screen set to 5 minutes before it blanks, if it sits there for a certain amount of time, madVR never recovers (picture is frozen) and I have to shutdown MPC-BE and start again.
A few nights ago I saw the screen blank and within a few seconds got the picture back up and madVR played fine. madshi, it looks like you may need to look at a way of re-establishing the connection for proper playback when this happens. |
