If I don't use the "softest chroma/sharpest luma" combo, I get the feeling that they interfere w/ one another. I'll try to come back w/ some screenshots ^^ PS: ah well, my Bronzés.mkv red text on black background test pattern(that was used in the OP) clearly shows that softcubic100 is much softer than spline3...breaking news But what I'm seeing in that cartoon doesn't really seem to appear on random static screenshots...basically it kills all the chroma noise and allows the luma to look much clearer and sharper. Otherwise what I see is the chroma noise interfering w/ the luma, rejoicing into a mushy PQ when put in motion..maybe my color blindness condition amplifies this, but anyway I enjoy having a noise-free chroma together w/ a very sharp and clear luma \o/ Last edited by leeperry; 7th December 2010 at 22:40. |

Hm, for some reason madVR drops frames like crazy as soon as I go full screen.
My source is 1080p x264 and my display is also at 1080p so I guess only chroma needs scaling in this situation. Funny thing is it doesn't matter which scaling algorithm I choose, madVR drops frames with every algorithm and it starts doing it as soon as I go fullscreen. In windowed mode playback is smooth. The problem only seems to be with 1080p material. 720p doesn't drop frames and I can run with spline3 on everything without issues. Does anybody else have this problem? My guess is this has something to do with exclusive mode... My system: Intel i7 930 Radeon 5850 (Catalyst 10.11) 6 GB RAM Windows 7 x64 MPC-HC 1.4.2745 |

Then try to disable it.
And check your V-sync (should be application controlled or off) and anti-alising and anistropic filtering modes (they should be application controlled or off --> a forced AA mode, like Morfological-AA with ATI cards, can kill madVR!) And check your GPU and CPU usage during the full screen playback... |

I have mentioned this to madshi and he was not sure why it was happening but suggested to wait until his exclusive mode code was complete. |

What you suggest blurs the chroma though. It is best to upsample chroma so that it is as good a match to the luma information as possible to avoid it bleeding out of the lines or causing other problems.
If you want to eliminate chroma noise, upsampling chroma correctly and then adding noise reduction to that image should give much better results. (but it is best to leave the source as-is) SoftCubic100 blurs chroma beyond the edges of luma causing colour to bleed out the edges considerably, resulting in desaturated colour. Spline is not a good choice either as you say. But spline does not look good with anything to me. It looks too processed/artificial from the way it treats the image like it's made up of curves to try and avoid ringing. Your test does not seem to be ideal as it looks like you are starting with a poor source where even the best chroma upsampling results in a very blurred image. On proper chroma tests or with better quality sources, Bicubic75 seems to do the best job of upsampling chroma information so that it is a close match to the luma information. Then choose your luma upsampling algorithm depending on how you want the image to look. For Luma, SoftCubic50 seems truest to the source without adding ringing/sharpening or removing detail/grain. |

FYI there a a group of us using JR Media Center pushing for the abilility to use madVR as the Video Renderer but it looks like it is not going to happen as one of the devs over there have quoted:

Some questions:
Is the madVR project dead? It s been a while since a new version came out so I was just wondering this. Also, there is a discussion on a forum in my country about standalone BRplayers like the Oppo or Dune player <-> HTPCs If a HTPC is properly configured with the use of MPC-HC, madVR renderer and FFdshow as codec, will this beat a high-end standalone player? I get one frame drop every 8-16 ours (calculated by madVR, checked with CTRL+J) with my HTPC and the PQ looks superb to me so how could a standalone player do this better. One last question: Am I correct that Fullscreen Autochange refresh rate function in MPC-HC does not work when using madVR as renderer? Last edited by THX-UltraII; 10th December 2010 at 12:47. |
