Are you watching 4K content on a display with a resolution higher than 4K? If so I would recommend NGU AA for chroma and NGU Sharp for luma. If your display is 4K or lower the options change.
Doubling is not useful unless you are upscaling, it does not automatically improve quality. There is nothing "stronger" than NGU and I would not say "super-xbr and NGU". NGU >> super-xbr.

NNEDI isnt even there anymore....ok so NGU. No I am watching the 4k stuff on a 4k display. Just want to maximize the quality. So NGU AA chroma and NGU Sharp for a 4k display doesnt do much? And there is the SuperRes filter and lots of stuff in upscaling refinement. But all that doesnt really do sth with 4k stuff on a 4k display?! Like it doesnt matter what to select under image upscaling like doubling or upscaling Jinc.....
So what exactly does improve the quality at least a bit? Last edited by d3rd3vil; 28th January 2018 at 17:21. |

If you're watching 4K on a 4K display nothing is needed except chroma upscaling.
If you want to refine the image, look in processing => artifact removal/image enhancements.

I find madVR's 'compress highlights' of HDR->SDR conversion to be too strong. It is trying to recover too much highlights, so much so that the result looks flat, without the necessary contrast.
For instance, a particular scene from Bladerunner 2049 bluray uhd with madvr HDR->SDR conversion - 130nits - preserve hue (hi, 50/50) - compress highlights (measure peak lum, restore details, AB-100, AR) It is worth noting that if I passthrough HDR to the display, what I see with my eyes is closer to bluray. To my eyes, highlights look bright and blown. @madshi, would it be possible to tone down the strength of highlight recovery, or provide an option? Last edited by bcec; 29th January 2018 at 00:32. |

Did you try 0% luminance reduction/100% saturation?
PS: please don't embed 1:1 images in the forum.

Preserve hue makes RM_UHD 1000 nit 100% Amp 100% Sat calibration patterns very pale and of all kinds of different hues depending on choice, so the one who doesn't have an HDR TV doesn't really know which choice is closest to correct...

Native or Copyback
Hi!
First of all I would like to thank you all the community that supports this software. I have some doubts I'm not sure about. First, which is better to use? Dxva2 native or copyback. I read that some options can only be used under copyback (image enhancements perhaps?) Then, under ngu sharp there is an option called superresolution, but I don't see any difference in using at maximum strength or not using it. My gpu is a geforce gtx 1080 msi armor, I5 7600 kabylake. Regards! |

Are you using DXVA2 Native decoding in LAV?

It seems to me the automatic bit depth switching in nvidia cp has stopped working as intended. Earlier if I would select 12 bit in 4k@23 RGB full and then switch to 4k@60, 4k@60 would work at 8bit and 4k@23 would continue to work at 12 bit. Now going back to 4k@23 (after a reboot) goes back to 8 bit. I like to keep my desktop at 4k@60. As an enhancement, would it be possible to allow to specify bit depth in auto display switching in madvr? That would remove all dependence on nvidia cp and its quirks.

You're not alone. Other quirky things too. MPC-BE, instead of quitting, replays and it's sporadic. Sometimes starting a title produces a black screen and many attempts later finally plays back perfectly. Other times, resetting 12 bit brings everything to life. Going to system image restore back to Jan 3rd prior to updating madVR, LAV, MPC -BE nightly, GPU driver, etc. Then slowly update one at a time and test a bit. If I get any results, I'll post back.

I guess welcome back from vacation for me. Thanks, Microsoft. So I got a new insider slow ring build (17074) and now 3D playback is seriously broken for me. I've reverted the nVidia driver and J River MC 23 to previous versions that were working before I left for vacation and the problem is not resolved. Essentially, 3D playback plays fine but the screen goes completely blank when I try to bring up the player UI. I've tried in my normal windowed mode and FSE and both exhibit the behavior. If it's playing 3D, any time the player UI tries to draw it completely black screens me. Awesome. Just awesome. Anyway, I know we're not even going to think about trying to fix issues for in flight insider builds of windows but I just wanted to caution others that are in the slow ring that if you see this behavior, it appears to be something MS has done. Now to figure out what the hell I'm going to do to get myself out of this mess....do I forge ahead with a fast build or do I try to revert...decisions decisions. Maybe I'll throw darts at my tv and choose. LOL

@austinminton I think madshi has said that the API doesn't provide him a way to set the display output bit depth.

It's not just the general "chroma things" that get touched either like with upscaling..the whole image basically loses some vibrancy with this enabled. Last edited by ryrynz; 30th January 2018 at 22:47. |
