New HDR to SDR
Hi Madshi!
I've been following the thread in Avsforum about the mapping from hdr to sdr2020 feature of madvr. I have no knowledge about all this science that is behind the software, but the movie they have chosen, Mad Max, I find it the worst of all HDR examples they could take. First time I saw it I also noticed weird things like blue colors within fires or gunshots or the shift from the color in explosions to red saturation and white highlights (already solved). I tested it yesterday night and I changed my settings from 200 peak nits, 25% luminance reduction and 75% ssturation to 200 nits, 30% - 70% and diffuse white to 50 nits spline. To my eyes I loose some general light, but not at all the frame like if I increase the peak nits value. I'm a JVC user too. Every other movie I've watched looks great with the sdr conversion and it even allows me to use my proyector in low lamp mode with a 120" screen. Perhaps there is place to improve, but I'm very happy with madvr at the moment. Regards! |

If you only watch films with content up to 1100nits, MadVR's conversion does a great job and there is very little to say, it's near perfect. Initially I had watched a few 1100nits films and I thought MadVR did a fantastic job (and I said so). It significantly improves the low end of the content for these titles. It's only when I started watching movies with more content in the highlights that I noticed some issues. MadVR's conversion simply compresses highlights too much with projectors, which causes the issues some of us are reporting. Feel free to post in the thread where Madshi has decided he preferred discussing this. It's open to everyone. Only MadVR fans are posting there (that includes me). It's not a MadVR bashing thread.

It should still be possible. If your profiles already include the chroma upscaling tab, then simple prepend another "if (srcWidth > 3000) and (fps > 40) "extraLowQualitySettings"" before all the other "if"s. If you don't have the chroma upscaling tab in your profiles yet, you can create another profile set just for chroma upscaling, in addition to the profiles you already have. madVR supports multiple different profile groups in each "folder". |

I'd still recommend to add a check for resolution in addition to "fps > 30", too, otherwise playing 1080p60 content will also trigger the UHD_LOW profile. Also, I'd at least use "fps > 31", because "fps" is a floating point variable, and there might be a movie which is flagged as 30.000000000001fps.

Madshi, regarding the 3DLUT, is it possible to shorten or make the 3DLUT name show in 2 rows, Displaycal generates pretty long 3DLUT names in example - madVR 2017-10-26 18-51 S XYZLUT.Rec709.bb0.8,2.4Gawt65.3dlut
It takes a lot of space in the OSD... |

if (3D) "3D" else if (srcWidth <= 720) and (srcHeight <= 576) "SD" else if (srcWidth <= 1280) and (srcHeight <= 720) "HD" else if (srcWidth <= 1920) and (srcHeight <= 1080) "FHD" else if (srcWidth <= 3840) and (srcHeight <= 2160) and (fps > 30) "UHD_LOW" else if (srcWidth <= 3840) and (srcHeight <= 2160) "UHD" else "4K" I will use 31 though, thanks for the FP info.

No! Now that we have the 3DLUT name in the OSD we don't want to mess with it, there can be no confusion if it displays the exact name. As madshi said, rename your 3DLUT.

Hi Manni! I know its not a bashing thread, I just dont have account in avsforums. Also I dont have the knowledge to speak about the issues, so cant contribute much besides a personal opinion if I like what I see although it could be wrong displayed. Everywhere I read about HDR the Mad Max movie comes into topic as being a pain in the ass for proyectors, therefore my connents. I had the hope you and Madshi could work together because this software is incredible and could get even better. Sad it's not happening. Sorry for my english, I'm from Spain. Regards! |

Also, those with weak CPUs sometimes can't even use YADIF on HD (it's too much for mine), and for those with weak graphics subsystem like Intel, DXVA11 can bring a much needed performance improvement Vs copy-back or software decoding needed for YADIF. The loss of quality must be less noticeable than the loss of quality due to YADIF.

Even better if you create a hard link for it (so you will also have the original filename).

A few screenshots, playing a H.264 video 640×480 in a maximized window on a 1920×1200 desktop, Windows 7:
both upscalers set to DXVA (the occasional drops are from stopping and starting the video several times) both upscalers set to NGU Sharp (medium / madVR decides; constant drops) GPU-Z report |

give bicubic 60 a try for chroma nearly everything is better than DXVA when using a nvidia and there current driver... you can add a folder named "ShowRenderSteps" in the madVR folder to get a better look at the rendertimes. and generally set the nvidia power settings to adaptive. optimal is buggy and a lot of people get major problem with it when using madVR. |

Afternoon all. Couple of quick questions for the more learned of you around here
If I have a 4k panel that is 60hz is it generally considered best practice to enter just 2160p60 under display modes in Madvr and nothing else? Second question is about using HDR luts. I produced a 3D lut with Displaycal using the Madvr BT2020 template. It loads fine in Madvr but underneath there are options for sending metadata to my display that defaults to DCI-P3. I'm presuming that I change this to BT2020 and enter the maximum nits of my display, which in my case is 430. Does that sound about right. Oh and I updated to the latest Madvr but despite it clearly saying 0.92.12 in the bottom left hand corner, I can't for the life of me see any of the new options that were mentioned in the changelog. Am I blind? Or stupid?.... Or both? lol |

I read another message which may have been deleted in the meantime...
Yes, I was confused about a little detail as well: Despite setting up medium quality, render stats display "high". Where do I do that? I do not have a mobile PC. This GPU is my only one, and I am not aware of energy saving features yet... Last edited by LigH; 6th February 2018 at 20:49. |
