HDR allows both higher contrast and wider gamuts than previous specs, we have never had content mastered to wide gamuts or with peak brightness so high before, only fake "enhanced" versions. Quote:

I am running Windows 10 Pro x64 with the creators update, version 1703, build 15063.138, with a Titan X (Pascal), driver version 381.65. I don't have any issues when using madVR with Direct3D 11 with present frame for every vsync checked or windowed overlay.

What HDR now is, is a way to _truely_ display that dynamic range, more like our eyes see the world, without having to squeeze the stuff into our old displays. Very dumbed down, but in your words: HDR-movie tech is exactly meant to show the detail of HDR _without_ that fake HDR look you talk about |

Win10's 'Film & TV' player plays HDR content correctly. It is just a rubbish player for everything else and has no support for high definition audio codecs like TrueHD or DTS-HD. I also notice using MPC I get a hell of a lot more dropped frames on 4K content.

Another quick comparison between Bicubic60 AR / NGU Sharp low / NGU Sharp med for chroma doubling :
As you can see, NGU Sharp is far from perfect for chroma doubling. NGU Sharp med is a nice improvement over NGU Sharp low, but still too sharp. @madshi Have you considered proposing other NGU variants, and unlocking the "NGU med" option for chroma doubling when "NGU high" is used for luma doubling ?

Nothing, just uninformed users buying into "newer is better" hype, while they can't even configure their player correctly for their hardware, and thus get dropped frames.
If you want to match the playback performance of the default video player in windows, set LAV Video to DXVA2 Native and use EVR as your renderer (not EVR Custom, and definitely not madVR).

And it's normal to see the win10 video player working with the new win10 hdr feature. Quote:

Has anyone played around with Game Mode on latest Windows 10 update? Game Mode can be turned on for any application, and it's supposed to allocate more cpu/gpu resources to that program.
Theoretically this should improve stability with mpc-hc/madVR, so you don't have background processes sucking resources during video playback, no? http://www.theverge.com/2017/1/25/14...de-explanation |

i can tell you what VALVE things about it.
i make it short they warn you if it is running and even give you a pop up that you should disable it with linked guides to avoid freezes and other major issues. feel free to try it out but i don't see a reason that it would help madVR what so ever. |

Its just a different API for the same hardware decoder. Performance wise its pretty much identical.

madVR is a totally different topic because it's for end users, so it's much less of a niche market, compared to video encoding. Quote:

Which "open window"? Is that window an "on top" window? The settings dialog should be "on top" all other windows, unless the other windows are "on top", too. That's a specific window style. Quote:

Whether the pre-installed win10 video player uses Media Foundation or DirectShow doesn't have much to do with HDR. The MS APIs to send HDR metadata to the display are totally separate from both DirectShow and Media Foundation. These new APIs are DXGI which is not video specific but is also used by games etc. Both Media Foundation and DirectShow software will have to use these new DXGI APIs to send HDR metadata to the display. So in other words: Your comment was totally pointless. Unless you're saying we all have to do what MS wants, regardless of whether it makes any sense or brings any benefits. Quote:
I don't really understand the argument that when doubling resolution of an RGB or YCbCr 4:4:4 image, chroma should be doubled with a softer algo than luma. What is the scientific or logic reason for making such an argument? Most photo/video software out there actually scales in RGB, which produces very similar results to upscaling all YCbCr channels with the same algorithm/sharpness. The only reason why I'm doubling in YCbCr instead of RGB is that it allows me to spend more GPU power on the Y channel (which is more important) than the CbCr channels. But if GPU power were no issue, I'd *always* use the same algo for all 3 channels, or even double in RGB. I would even remove the option to choose a different chroma doubling algo. IMHO the only valid reason to use a different chroma algo for doubling is to save performance. Last edited by madshi; 19th April 2017 at 14:18. |

The result is unnatural and ugly for me. Quote:
There is visibly room for improvements. Quote:
Chroma upscaling is not perfect either, so upscaling the RBG or YCbCr 4:4:4 result of a 4:2:0 content with the same algorithm for luma and chroma does not seem logical. It would be logical if the source material was RBG or YCbCr 4:4:4. What is your opinion on this ? Last edited by Neo-XP; 19th April 2017 at 15:17. |

My opinion is that any problems you're seeing are more likely coming from suboptimal chroma upscaling (4:2:0 -> 4:4:4) than from chroma doubling. As I mentioned a couple times before, I do plan to create an NGU algo for chroma upscaling which makes use of the luma channel for guidance. Once that's implemented, artifacts like aliasing etc should be lower in the chroma channel. I would at least like to wait until then before I add any wild option mixes for different luma vs chroma doubling...

don't get me wrong, It looks pretty good in HDR, it's just a bit too much color saturation and a green tinted push but nothing like watching an SDR source in HDR mode. |

I can't wait ! In the meantime, I hope I would be able to select NGU med for chroma doubling without having to buy a new GPU to be able to use NGU very high for luma As already said and tested, NGU med is a big improvement over NGU low for chroma doubling. I have already maximized all the other options in madVR for my GPU and I have GPU resources to spend For fun, here is a little comparison between Bicbic60 AR (with NGU Standard very high for luma) / Bicbic60 AR (with NGU Sharp very high for luma) / NGU Standard med (with NGU Standard very high for luma) / NGU Sharp med (with NGU Sharp very high for luma) for chroma doubling : In order of preference : NGU Standard med (with NGU Standard very high for luma), Bicbic60 AR (with NGU Standard very high for luma), Bicbic60 AR (with NGU Sharp very high for luma) and NGU Sharp med (with NGU Sharp very high for luma). Soften edges at 1-2 can also help a lot here with NGU Sharp for chroma doubling. PS : usually, I like very sharp images, but this new NGU Standard algo is very good !
