@MSL_DK
Tiny changes in XYZ values are causing yCMS to produce 3DLUTs with drastically different color luminance clipping results. If you have better results using measurements from one source compared to another, it's just a fluke. This is likely the same madVR forced TV range on PC range test pattern bug which has existed since early yCMS versions. Last edited by cyberbeing; 10th December 2012 at 01:43. |

So for your setup... madVR input range: 16-235 madVR output range: 0-255 GFX: 0-255 TV: 0-255 yCMS has a problem maintaining identical luminance range between Primary colors when madVR treats PC range video as TV range with BTB/WTW, and then expands back to 0-255 (i.e. clipping test patterns).

This is not my goal, but I have tried with madVR: 16-235 GFX: 0-255 TV: 16-235 This does not solve the problem. I still get this weird result |

I would be nice if yCMS supported gamut correction below 100% sat. |

Creating a 3D LUT for madVR Color Correction
I posted some instructions that work for me over at the JRiver forum: How To Get Perfect Video Color

yCMS was never a great solution, it worked well for mapping a larger gamut to a smaller one but it is much better to create a 3DLUT with DisplayCal (also free) or similar.
