You should use the native gamut of the display and create a 3D LUT to BT2020 or DCI-P3 if your display doesn't have a BT2020 or P3 mode. What matters most isn't the saturation at 100%, it's the way saturation will track within the gamut. You can get very decent results even with a display not able to reach much more than rec-709 as long as the saturations are tracking BT-2020.

maybe AA should be renamed so it is not so misleading and unlike the other NGU algorithm quite different. and it's quite an "issue" for me because i'm generally favouring AA for bad sources that need RCA. |

i should have been a little more precise in my original wording - most current tv models with UHD displays using rec.2020 can still not display the full range of this color space ( or the full range of DCI-P3 ), and in their specs this is quantified in a % - for ex a 2015 higher end samsung UHD tv (model 65JS9500) (using rec.2020) can still only display 91% coverage of DCI-P3 colour gamut - in comparison, my 1080p sony tv panel (with HD using rec.709) is able to display 94.7% of the DCI-P3 colour space (using the x.v.color setting i presume), and it can accept this signal over HDMI input (and my HTPC can output x.v.color) - DCI-3 gamut and the x.v.color gamut are VERY similar in size (but use slightly different primaries) so if i can convert a 4k video (yuv 4.2.0 10 bit) to 4k RGB 4.4.4, and then in the last conversion step (resolution 4k to 2k) i am hoping to maintain as much of the original color information by converting the rec.2020 UHD color gamut % used by the original file, to x.v.color at the highest % my display can cope with (instead of squashing it into rec.709) i dont really know what Lut's are or how i can use them ( ? look up tables for the RGB primaries used by the display ?), i was hoping the conversion from UHD video to HD (but in x.v.color instead of rec.709 ) could do this in madvr is there an easy way i can find out my tv model x.v.color primaries, and then create a 3D lut file, and then load it in madvr ? or would it be possible to enter my information directly into madvr maybe |

I read this in the other thread about madvr settings.

That option has been removed now. I don't think that the requirements have changed.. Still NGU/NGU sharp high/very high.
I believe madshi was looking to add RCA for free with NGU AA it's just as huhn said quite different so requires extra code. Last edited by ryrynz; 5th February 2018 at 04:22. |

To clarify:
When RCA tries to run for free, will it still run on NGU'd chroma channel, if the luma channel is not scaled by NGU/already full res native? Does the checkbox "process chroma as well" do anything when the algo tries to run for free? |

From madVR itself and happening on both different player.
But to be sure will switch on EVR to confirm it at 100%

Confirmed it comes from madVR and the OSD message in left upper corner is the same font as when changing madVR option from keyboard shorcut, so yes @Clammerz i'm right to asking this here

Thanks for the new build will try asap So the version from LAVSplitter is on older one, so you are right, i have installed a tool this week-end that install on older version of LAV suite. Sorry, that's shame that i didn't look into it myself. LAVAudio and LAVVideo was the correct version but not LAVSplitter.

madVR is displaying it but it's your player providing it as LAV nor MadVR give any prompts to update, so.. not appropriate here. Ideally anything video related should be as up to date as possible anyway.
For those serious about video playback the nightly life is a well tread path. Given the changes in LAV and the time since last release it's probably not far off a "stable" release |

However, if you have a meter, you can switch your TV into the most "native" mode it supports (whichever produces the widest colors/gamut) and then use a 3DLUT to calibrate it for BT.2020 content. Your TV doesn't even know it's receiving BT.2020 data. You should get the max out of your TV that way. Won't be possible without a meter, though. And with a meter you'll have to dive into the depths of calibration software, which can be a little scary sometimes... Quote:

Actually, this is a rare exception. I've recently added detection for a specific range of old LAV builds, because I regularly received crash reports caused by them. So this specific hint actually comes from madVR. It's not a regular "just so you know, there's a new build available, would you like to update" message. It's just a detection for a specific very old unstable LAV version. |

Yes, it is. But I can't magically make it work by just changing some code lines quickly. Each RCA strength with each NGU version with each NGU quality level is its own separate algorithm. If you multiply the variants you'll see how crazy much work that is. You can already look at how the madVR.ax file size has increased in recent versions. It's all due to the high number of new algorithms, due to combining NGU Sharp + RCA.

Regarding this topic of ngu sharp + rca, must we check the rca option too? If I do so the rendering times increase a lot (like 55ms) and the movies in UHD dont play smooth, start dropping a lot of frames. I use a nvidia gtx 1080. Regards! |

Yeah, you should have 'activate only if it comes for free as part of NGU' as well in your case.
Also remember that NGU gets bumped up to high/very high as well that's likely the cause for the render time increases. Last edited by ryrynz; 5th February 2018 at 13:45. |
