Unfortunately, I am not aware of any software which convers high-precision measurements from an ARGYLL results file or an ICC profile to a 3dlut... there is a need to fill here! In fact you can already approach this by loading the ICC profile into Windows. There are two problems though: (1) it is very probable the card's VideoLUT won't do any dithering, and (2) my experiments seem to show that although individual RGB channels are corrected, the primaries (gamut) are not. Anyone know why loading an ICC profile into Windows fix gamma but not the gamut? Maybe that's because I'm using Eye-One Match instead of ARGYLL, and the ICC profile generated by Eye-One is at fault? I'll try with ARGYLL as soon as I get the time. Last edited by e-t172; 7th June 2011 at 11:30. |

I asked tritical if I could compensate for those saturations in a 3DLUT and he said no...so that settles it That's because the graphic card's CLUT is 1D only, you need a 3DLUT to map gamuts. It was confirmed to me by Graeme Gill BTW |

My laptop has an 8600M-GT video card and has the following ports on it: HDMI, S-Video and VGA. I have my external monitor hooked up to the VGA port and my projector to the HDMI port. I press Function + F6 and the video gets alternatively output through each port if a device is plugged into it (internal laptop video screen --> the external monitor (video output only through VGA port) --> the projector (video output only through HDMI port) --> back to internal laptop screen). Basically I'm just selecting the video display (device) on which to view the operating system desktop and thus selecting which video display device on which to view the videos I am playing.

@leeperry
I can partially accept your reasoning but I would never ask or even accept money for a calibration if the overal result of my changes is worse than the default state. And the objective way to figure it out that you check some (>40) random colors and of course judge the result sumjectively. If the overal result is worse then I would ask for apologise, restore the factory settings, leave the fild, refuse any other contracts for the particular display model and recommend it to my collegues to do the same. I know, this is why I am not a real pro. If you mentioned Samsung... Did you saw their latest PDPs? I wouldn't give my 51D550 in exchange for the much more expensive 50GT30. And I simply unable to understand why many people prefer the Panasonic PDPs (I talk about 2D of course, 3D is a joke anyway...). Well, may be they never try to set up the settings properly because I admit that the THX mode on Pana is almost "spot-on" (given the possibilities) and Sam requires a complicated ad long calibration. (I fully reconfigured my ADC/WP setting in the SM and played a lot with the user OSD too but it worth it...) I don't even use 3DLUTs anymore because they make very slight difference and the slightly off state looks subjectively better or me. (And ah yes, I would never play games or watch movies on LCD anymore, p/H-IPS or not...) And I the thechnoly is alredy here: 3DLUT. (Professionals widely use it already.) It could be carried out as a fully automated process. But no... An IFS guy will ask for even more sliders in the OSD. (I image tercier color sliders and +1 point in every year for grayscale to make it look like an improvement...) |

Let me say it again: The task of a decoder is to decode. It is not the task of the decoder to do anything display specific. Doing display specific things is the task of the video renderer. So setting your decoder to convert video level source material to PC levels is conceptually "wrong", from my point of view. Quote:

As a nice workaround for now, you can simply press Ctrl+Alt+Shift+Y, that will make madVR switch between video <-> PC levels on the fly. This way you don't have to open up settings dialogs and search for the level setting. Quote:
You think you know that better than me? Ok, thx. |

Do you have a meter to measure your display? That's a requirement if you want madVR/yCMS to calibrate your display. |

Surely, D65 and 24Hz take some time to get used to...and I've got a hard time believing that a calibrated display would look "worse" than uncalibrated. Crushed whites, dark blacks, FUBAR gamma curves...blueish/greenish teints....you can't fix those w/o a colorimeter. Either you learn the tricks of the trade and buy an Eye One, or you call a pro and pay for it. It'd be like asking a pro to tune a POS old car, and then complain that the results of his work don't quite meet your expectations. Nope, I've got no interest in Samsung whatsoever...I'm only interested in the high level of expertise Joe Kane provided them w/ on those high end DLP projectors. We need to learn from it, and get it all embedded within mVR. Last edited by leeperry; 7th June 2011 at 12:24. |

No, I used a "perfectly" calibrated H-IPS for a year with every possible corrections.
I stopped using 3DLUT since I calibrated my new PDP with it's hardware controls and 3DLUTs make very slight difference. And considering the observer metamerism and sensor imperfections it's virtually nothing but the non-3DLUT corrected results looks subjectively better. (A very mild oversaturation is every directions.) My setting are still D65, gamma ~2.2 But the higher contrast ratio and smaller native gamut (did you care about the observer metamerism when you think you use offser WP? May be it's visually closer to what you called D65 on another display...) produces a noticably different image. (That' why I take this question less seriously now...) |

I guess it really doesn't matter does it? They are all pretty much digital devices and I don't think I would get a better picture on my projector vs the Acer external monitor even if madVR would recognize it properly, right? |

I'm not really an expert on this. Maybe someone else can help out. If not, you could ask in the yCMS thread. |

Hi madshi.
Thanks for the new build. But I have a problem with it. Until now, I've been using 3dlut files (generated with yCMS) in madvr, and was using this command for color correction: Gamut_Measurements 0.6350 0.3321 0.2890 0.6007 0.1528 0.0647 0.3127 0.3294 just as it was intended to be: Gamut_Measurements redx redy greenx greeny bluex bluey whitex whitey But now, with the new builds (and with the new madvr version), this is not possible, and the procedure seems to be as in this example: Gamut_Measurements 1 21.26 0.676 0.321 71.52 0.308 0.685 7.22 0.144 0.045 100.00 0.3127 0.3290 yesgrey told me that the first column (bold) was the Luminance, but when the calibrator did his job on my TV, he gave me the xy coordinates and they were 2 numbers for each component, not 3!! So I don't have that info. Is there any way to generate 3Dluts or use madvr color correction without luminance? How can I solve this? Thanks in advance. |

@cyberlolo, you really only need to ask in one thread. yesgrey and I are reading both. I'm sure you'll get a reply from yesgrey in the yCMS thread. Personally, I don't know the answer, but I'm pretty sure there is one.

LAV Splitter LAV Audio Your favorite video decoder based upon your hardware (LAV CUVID for nVidia to do GPU decoding and for me Cyberlink Video Decoder for HAM mode for GPU decoding to offload decoding to your video card) ffdshow raw video filter for subs *UNLESS* you're using MPC-HC in which case use their internal sub renderer With that combination you can just load the index.bdmv file in your BD folder and it will play the main movie. Or you can open an MPLS file. Or you can open your m2ts file. However you wanna do it.

@madshi
Was your fix for the sync problem of the interlaced display mode that you disabled 1080i59? I mean... was it the problem that my display doesn't really support it? I kept these settings for v0.63: 1080p23, 1080i50, 1080i59 and now my display mode remains progressive 60.000Hz with 29.970fps materials. Could you explain it please? |

This time it switches but the display mode is 1080p59, not 1080i59 (the setup is still: 1080p23, 1080i50, 1080i59) -> log (1080i50 works)
But I found this: http://www.100fps.com/, and now it sounds like a bad idea to output interlaced signal (see "resized before deinterlacing" -> the chroma map is resized by madvr...) Could somebody recommend a high quality deinterlacer filter? (Or which one is the best out of the many in FFDShow?) Last edited by janos666; 7th June 2011 at 14:45. |

If you have an NVIDIA card, yu can use my LAV CUVID to use hardware decoding & hardware deinterlacing (best quality deinterlacing you can achieve with madVR, IMHO)
