Can anyone please suggest a proper shader to correct white balance?
I need to tweak R,G,B Levels (not Contrast, Brightness or Gamma) to correct LED projector extremely blue light source in software. The hardware color correction is extremely poor and leaves an uneven colorful (red and blue) gradients, so it is unusable. Thank you.

Use a 3DLUT for correction.

I need a quick white balance fix without calibration.
I wonder why madVR hasn't got an R,G,B sliders if it does have Contrast, Brightness, etc.. Maybe I can quickly lower the Blue and raise the Red via YCMS?

I am curious as I was not using Reclock so the best I could get was it repeating anywhere from 30minutes to over a few hours (changes often) but using 47.952. WhenI tried 24 or 23.976, the repeat frame was like every few minutes. Of course with reclock its rock solid but I am not sure how much damage reclock is doing to the audio etc. | What will be considered a GOOD rate for the 1 frame repeats ? Also, not sure if it was reported but when using the 64 bit of madvr, if I use NEDDI3 the screen is just black. Lancz and others work fine. |

HUE has no effect on Luma.
I need actual RGB sliders like in a TV for software white balance adjustment. Any help? Sorry for the non madVR related question, but I hope madshi would be able to implement these simple R,G,B sliders in the Color & Gamma section of madVR. I ask because many TVs color management is a complete rubbish; The simplest color temperature adjustment results in a a rainbow greyscale... So my goal is to keep the hardware at Standard (50,50,50) where the greyscale is uniform (native light source), and change the temperature via software. Oh yes, without using 3DLUT or calibration, just by eye.

That is why you'd need a LUT - to compensate for the mismatch due to the non-linearity of panels. |

whats the proper way to diagnose a problem?
the fullscreen exclusive mode wont play nice on my PC no matter the setting in windowed mode everything works fine and I get around 30% GPU utilization. in FSE mode I get decoder queue 14-17/16 upload queue 5-8/8 render queue 5-8/8 present queue 1-8/8 and around 35% GPU utilization. changing scaling algorithms doesn't change those numbers. win 7 ultimate, nvidia geforce 210, driver ver. 341.44 how can I identify the problem? |

However, that was old code and won't work until someone invests time in getting it to work. Or, until someone rewrites SupresRes for AviSynth. So, is there such a big difference between the way madVR is programmed and what AviSynth requires?

you find overlay mode under general settings and you can disable FSE mode there to if you have problem with it. i my personal experience overlay works best. |

I like overlay myself, it responds a little slower in some situations but is reliable and doesn't need to switch in and out like FSE. It also allows madVR to control all aspects of a calibration for higher quality when using a monitor profile in Windows.
You do need FSE disabled to use overlay in full-screen but it doesn't need present frames in advance checked (or not checked), it uses the number of back buffers set in the windowed page with "present frames in advanced" unchecked but it will use them even if "present frames in advance" is checked.

not 100 % true.
http://bugs.madshi.net/view.php?id=271 and on my windows 10 system i get "~my driver doesn't overlay" when i disable present frames in advanced for window mode. just activated present in advanced and it will work on nvidia and intel . |

How odd, Windows 10 is weird.
Does it use the number of buffers set when "present in advance" is enabled? On Win 8.1 Overlay reports "back buffers" in the OSD and uses the number from the page when "present in advance" is disabled. Overlay works either way on Win 8.1 x64.
