![]() I invested a lot of time in this and the only conclusion so far is that no matter what I do the results on screen are from acceptable to outright terrible. I have no clue how to calibrate my monitor for mpv so that I get accurate colors and preserved contrast. Obviously I was wrong, made same settings on a laptop and black crush is terrible with icc-profile="1886.icm" and display gamma 2.2. In case I want 1886 gamma I set the display to also use 1886 gamma profile same as the one manually set in mpv. Given that mpv internally uses a gamma of 1886 as standard, I let it use an icm calibrated for that standard with icc-profile="1886.icm" option, and I leave the monitor calibrated to gamma 2.2 or anything else that looks ok, this results in color correction in mpv respecting the 1886 standard and because the gamma 2.2 is applied to the display it will be applied on top of the color corrected video. Think I finally found a fix for my contrast issues. I don't know why 1886 is considered like the industry standard, it just looks terrible on low end displays and only partially acceptable on high end displays can't even hit a gamma of 2.4 What could help you decide some better more contrasty look that might be better for more people would be gimp with color management turned on, intent relative colorimetric, no black point compensation. I tried davinci resolve calibrated to 1886 results are very similar to mpv very close so mpv is accurate but only when using 1886.Īlso noticed that changing black level offset from 100% or setting black level manually to 0.0001 does not really help and I'm not sure why. Taking screenshots is totally useless what you see on screen is different than what ends up in the screen capture, hence all the bugs with inconclusive endings. This is my take from experimenting with different settings. But with more manipulation color accuracy degrades mostly visible on skin tones. For a gamma 2.2 the video gets lightened so that adding a gamma ramp from GPU still results in 1886. ![]() So turning ICC on off shows a huge difference in contrast, but the ICC auto version looks like 1886 regardless of what gamma you use. The confusion comes when using something like gamma 2.2, in that case icc-profile-auto=yes the video will be manipulated to look like 1886, like mpv compensates against the gamma ramp of 2.2 to make it 1886 (no idea how to call it). ![]() icc-profile-auto=no because desktop is also calibrated to 1886 (assuming monitor is close to 1000:1 contrast). Internally mpv uses gamma 1886, if someone calibrates screen to that standard by the book, using icc-profile-auto=yes only results in colors looking more accurate no noticable contrast change vs. I'm starting to understand why there is a lot of confusion about calibration in mpv. There needs to be a lowest level of black that mpv sends to the screen, is it 0.0001, 0.0175? A contrast of 1000:1 I'm not sure how to calculate the black level from it.
