yesgrey3, I need some more help, please.
What about this solution for my levels issue? Output Full RGB from the card (or Limited, there's no difference), set madVR to TV Levels (no conversion), but set my TV input to expect RGB Limited (16-235), so let the display make the conversion instead of ffdshow's levels filter. Then, ok, I'll have a compressed desktop, but for video, that would work, wouldn't it? I've checked it and lowering a bit the contrast in CCC, you get WTW too and without banding. What do you think?

Ok, we'll keep waiting. Thanks again! BTW, in this thread (http://www.avsforum.com/avs-vb/showp...postcount=5558), sotti has made some tests with the YCbCr 4:4:4 output, that seems to show that YCbCr is no converted into RGB and then back to YCbCr in ATI cards, as the color accuracy matches the one achieved by a standalone Blu-Ray player. Does this mean that the optimal pixel format for ATI cards is YCbCr instead of RGB as we were thinking until now? Last edited by cyberlolo; 27th February 2010 at 12:04. |

If you want your HTPC to work simply as a Blu-ray player, without performing any corrections to the displayed image, then you should output as YCbCr. If you want to correct your display's flaws using your HTPC, you should output as RGB.

I don't have one, and probably never will, so my personal choice will always be RGB. |

There's some people asking (like me) if madshi continues with the development of this renderer, or if version 0.11 will be the last one. Does anyone know this? Why madshi hasn't post anything here for more than a month?

He has become a clone of Haali.
Busy with his job and real-life, but slowly working on madVR in his very very limited free time. It's not like madshi has stopped lurking around Doom9, he was last seen a week ago. Until he comes around this thread and announces he has halted any further development on madVR, assume it is still ongoing. Last edited by cyberbeing; 28th February 2010 at 23:04. |

MPC-HC madVR, RGB Full, (AVIVO Dynamic Range doesn't count) MPC-HC madVR, RGB Limited, (AVIVO Dynamic Range doesn't count) MPC-HC madVR, YCbCr 4:4:4, (AVIVO Dynamic Range doesn't count) This one is more relevant even. It's TMT3. We know madVR is converting to RGB for the card then to re-convert to YCbCr, but with TMT3 and the other commercial players it's speculated that the protected video path allows for direct YCC passthrough TMT 3, YCbCr 4:4:4, DR Full TMT 3, (RGB Pixel Format doesn't count), DR Full TMT 3, (RGB Pixel Format doesn't count), DR Limited YCbCr here shows even more banding than with madVR. In this case I believe the YCbCr setting compresses levels, thus you need to choose dynamic range Full in Avivo which expands again. Last edited by Andy o; 28th February 2010 at 23:11. |

So, when using madVR, RGB output is always the preferable option. |

So now it's official that madVR is still in development. Great news. Last edited by cyberlolo; 2nd March 2010 at 21:22. |

1) Set madVR to TV Levels (no conversion), graphics card output and TV input to Full RGB (0-255), and adjust TV brightness so that levels 0-16 are total black. 2) Use your new version of cr3dlut (when released) to have the output calibrated at 16-255, so we'd need nothing else to adjust in the TV. With both of them we'll have an optimal levels calibration at 16-255 to watch videos with an HTPC outputting RGB: that is to say, levels 0-16 as total black, preserving wtw (to simplify, in this case we'll assume 255 peak white as optimal, although you adviced to set it at 245), and without banding. But which one of this two options is better, and why? Last edited by cyberlolo; 4th March 2010 at 01:53. |

IMHO, probably would be (2), because it would use better the on/off contrast ratio of your display, hence giving you images with a little more contrast, but it would not be as simple as that, because the gamma used will also have a big influence in the output image...
There are no strict rules in this. It will always depend on personal preferences... Last edited by yesgrey; 4th March 2010 at 11:30. |

If that's so, we'd be lossing much valuable info: Quote:
P.S. Sorry for the long post, but I really need to understand how this is working in order to achieve the better possible PQ. Last edited by cyberlolo; 5th March 2010 at 01:57. |
