Regarding the upcoming HDR metadata support… will we need to watch out for the HDR format "war" when choosing a display for playing HDR content from a PC with madVR? From what I can tell there is HDR10, Dolby Vision and HLG. Which standards do the nVidia/Microsoft APIs support? Will we need to be careful when shopping for TVs? Does it even matter?

In any case, Dolby Vision is not what PCs send, right now its probably HDR10, and may also be HLG in the future.

Also, when you start working on implementing the automatic HDR-mode, please consider making it an option to remove the HDR-flag (so basically what MadVR does today). Owners of JVC projectors want the HDR-data to be stripped in order to get more control over the projector settings. I know this is the opposite of what most users desire, but having this option would be very welcome by the JVC minority. Thanks for all your hard work |

1) NGU Standard seems like a good match for the sharpness of NGU AA, but
2) I really like the Anti-Aliasing capabilities of NGU AA, it makes a very visible difference in some cases for the material I watch (mostly livestreams and youtube videos, which are all fairly heavily compressed). I think a certain level of compression just inherently causes aliasing, and NGU AA does wonders for it (in certain cases), where NGU Standard just looks softer than NGU Sharp. If anything, I'd kind of like a sharper version of NGU AA if that's possible. I like the crisp edges of NGU Sharp, but unfortunately for the material I watch the crispest edges are the compression artifacts :P By the way, do you think you'll be able to make direct quadrupling work for NGU AA?

3DLut edge problem

It was the Sliding Power gamma during calibration that was doing it, now changed the gamma function. Not sure of it's a bug on Calman's side, still waiting on their reply. |

I finally managed to solve my video performance issues :-)
1. By disabling zoom reduce ringing artifacts in MadVR -> processing -> artifact removal. 2. By disabling crispen edges in MadVR -> processing -> image enhancements and enabling it instead in upscaling refinement settings only. 3. By disabling zoom small black bars away in MadVR -> processing -> zoom control. Making these 3 changes results in significant performance boost whic translates in much lower average frame rendering times :-) |

Question:
When Madvr converts UHD HDR to SDR does it also convert colors from bt2020 to bt709? also will there be a setting for adjusting the PQ gamma with HDR material on SDR tvs? as it is now to get down the APL with UHD HDR i need to select much higher peakbrightness than the tv has. and with that i think highlights dims down to much. what i want is to have the highest possible brightness for highlights but to tone down the rest of the image to where it should be around 100nits APL. you cant do that now. you can with the Samsung K8500 UHD player with adjustment of Brightness and Contrast in picture mode user menu with that you can adjust contrast to get max details in bright areas without clipping with UHD HDR material. i wish madvr had the same setting Last edited by Patrik G; 11th April 2017 at 16:21. |

Maybe "NGU AntiAlias" could be better in all cases than NNEDI if it was a little more sharp and produced/accentuated a bit less artifacts. But for now, each one have pros and cons... Do you plan to keep all the NGU variants for chroma upscaling ? For luma doubling though they are all good, but if one have to go, it should be "NGU Soft" because "NGU AntiAlias" could be used instead if someone wants a clean result without the sharpness of the classic NGU. "NGU Soft" is too soft. 2) "NGU Standard" removes dark halos, "NGU AntiAlias" does not. The edges are cleaner with "NGU AntiAlias", because "NGU Standard" seems to produces artifacts on them (probably while removing the halos). Is it not possible to have them both combined in one "NGU Standard AA" algo ? Also, I noticed that "NGU AntiAlias" shifted the image a little, is that normal ? 3) Yes, it is useful at 1 or 2 to soften a bit the razor-sharp edges of "NGU Sharp", even more when using it with "direct quadrupling". 4) No, "double twice" produce a very superficial result so it can go IMO. Anyway, I'm very happy with this version now. Just madshi. Last edited by Neo-XP; 12th April 2017 at 02:44. |

Thanks for the tip. However, I'm still getting 1 frame drop every 33min. Originally it's from every 33 seconds
