@suanm: madVR already does chroma upscaling of 4:2:0 to 4:4:4 via the GPU, it's basic stuff.
What's your source format? Can you post a screenshot of the madVR OSD to see what format it's receiving from the video decoder?

madVR has an amazing number of options for upscaling the chroma from 4:2:0 to 4:4:4 and they all run on the GPU. NGU AA high is my favorite method for 4:2:0 to 4:4:4.

A big thank to you for your reply. I posted two screenshots on the post board. Second: I'm surprised there is no chroma appeared on madVR OSD.i don't know what's going on?Chroma is not displayed all the time when the playback of 4K UHD movies Third: Due to no chroma used, the conversion of 4:2:0 format to 4:4:4 format doesn't always work.This leads to worse video quality.I don't know how to solve the intractable problem. |

hey i just want to give props to madshi.
Madvr is so great at upscaling 1080p to 4k , it even looks better than some native 4k stuff http://caps-a-holic.com/c.php?a=1&x=...1&l=0&i=6&go=1 |

This is the only recent commit, so 35 is probably functionally identical to 34. Might have been built with a slightly newer version of Visual Studio.

If yes, turn off the trade quality for performance option "scale chroma separately, if it saves performance". This option will let madVR avoid scaling chroma if it doesn't have to, instead scaling luma to reach the same resolution as the chroma. Effectively this is still converting to 4:4:4, but it is probably lower quality than scaling chroma to match the luma and then downscaling in RGB.

Madvr stops working on Win 10
Hi all,
I am using madvr 0.92.14 on win10 build 1703 and it stops working as soon as I want to change settings (see attachment). Any idea why this happens or how to troubleshoot it? Thanks. Ronald |

Have you activated supersampling? (doubling action - always supersample). It takes a fair amount horsepower, so you might need to adjust your settings for 4k movies when it's activated.
