I'd first take out Notepad and copy any important madVR profile rules and save them. Then remove your settings.bin file and place it outside of the madVR installation folder. Finally, reset your madVR settings from the installation folder and see if the issue has been resolved. You can then paste your previous settings.bin back into the madVR installation folder to restore your old settings. The Notepad file is just there in case anything goes wrong.

You can't disable your display's tone mapping. You can disable dynamic tone mapping if it has this feature, but you can't disable the gamma (PQ) curve in the display, which is where the tone mapping occurs. You could calibrate the display with a colorimeter to follow the PQ curve as close as possible. That would be the closest to avoiding any form of tone mapping for pixels that are within the display's brightness capabilities. Even then, the display might change its curve to match the brightness of the content.

Based on the photos posted, the tone mapping has improved considerably from the previous build. Some may miss some of the extra saturation, but the improved color accuracy and highlight detail makes up for it. If those images came from the recent test build, I would just put it to print and be done with it.
Those shots do make it look like saturation was slowly removed from the picture over a six month period Obviously, there was more to it than that. Trial-and-error is sometimes the best way to go when you don't know where you are going...

I'm using Windows 10, nvidia 1080ti, latest nvidia driver, Kodi DSplayer, latest LAV filters and XySubfilter. The video plays fine until the first subtitle line should show up. It hangs before rendering the subtitle while the audio continues playing. |

I sent madshi a debug log and freeze reports as requested. Hopefully something will be apparent from them. |

I guess dithering can only do so much? |

(Besides, reportedly the "process HDR content" feature is currently broken. Will have to investigate.) Quote:

Not sure about your image quality question, either. Why would 60Hz contain a Bicubic downscaling step while 30Hz does not? What does refresh rate have to do with resolution or with up/downscaling? Quote:
v0.92.16 is using a different formula to calculate the final saturation compared to v0.92.14. In many cases the final saturation is a bit lower now, but in some cases, it can also be higher. Saturation is generally a very difficult parameter to dial in. Using more saturation is nice, but we have to avoid overcooked skin tones. Also, trading in some saturation for added luminance can sometimes help rendering highlights with more detail. I'm pretty happy with the algo now, in any case. Quote:
I do wonder why you see the banding artifacts in RGB 8bit Full, and not in YCbCr 4:2:2, though? That doesn't make too much sense to me - unless your TV applies debanding for YCbCr 4:2:2 input, but not for RGB input? |

About the screenshots comparison, I don't know anything at HDR (and I'm not really interested). In the end, the best images are the one with better contrast isn't it ?
Is it right to say it looks exactly like "dynamic contrast" options from TV ? |

You might not be interested in HDR, but HDR is interested in you! Er, by that I mean that HDR is probably going to become more common as time goes on, so if you don't have an HDR display you'll need some way to display that content on an SDR display without it looking awful.
HDR basically just lets really bright things (like sunlight) be really bright. If you don't have a display that supports that kind of brightness, you need to reduce the brightness of the footage in a way that still looks natural - so you don't end up with a scene shot in daylight that looks like it was shot at night, or a scene where all the bright things are just pure white and you can't see any details. That's what madshi is currently working on.

Maybe a stupid question, but I remember reading on this very forum that we shouldn't use the Sony Camp demo because its mastering metadata was rubbish.
Is there another, correctly encoded, source? Or does that not matter anymore with the newer madVR versions and it can handle material with incorrect metadata?

not sure that would make any difference on my first gen 4k OLED EF9500 as SDR and HDR peaks are almost identical - see here.

Speaking about SDR brightness, how do you guys manage the different brightness between HDR converted to SDR, and actual SDR? Surely one doesn't want the same brightness levels there. Manually? TVs certainly don't have much automation to speak of.

As far as I know you'll need a service remote or a phone which has an IR blaster to access the service menu. For an android phones the app is called AnyMote not sure about iphone. I can understand why LG limited the brightness for SDR. There are more and more cases with burn-in and if people could watch CNN or whatever all day with 500+ nits they probably would...

if you have this happen again all you have to do is open task manager and restart explorer and it is usually fixed immediately, media player can remain open during this. you can look up otherways to restart explorer more conveniently, i recommend NOT using any of the "gracefull" commands as it sometimes stalls on closing. |

Another reason why i ask masters here about 30hz and 60hz. In 3840*2160,60hz standard and luma>soft(high),chroma>soft(high) mode,the playback of 1080p moves drops frames.However,when i choose 3839*2160 60hz and luma>soft(high),chroma>soft(high) mode,No frames drop. I looks up the madVR list,it displays the 3839*2160,60hz mode has been optimized by madVR.But 3840*2160,60hz is a standard mode,it's not been optimized by madVR yet. So i guess this is why no frames drop in 3839*2160,60hz mode.Unfortunatedly,when madVR runs,luma value goes >soft(high)<Biscius 150 AR,not simplex soft(high). When i switch to 3840*2160,30hz,chroma soft(high) and luma soft(high) mode,no frames drop yet. So now i can't be sure which image quality is better between 3839*2160,60hz, luma>soft(high)<Biscuis 150 AR and 3840*2160,30hz,luma>soft(high). Because i don't know if madVR makes 4:2:0 convert into 4:4:4 in 30hz mode,furthermore if luma quadrupling upscaling works correctly in the same 30hz mode. Thank you,master,for reading my endless remarks |
