madVR - high quality video renderer (GPU assisted)

[LordX2]

Is there a way to setup a 'hot key' for the gamma setting? It's my only difference between watching hdr and 1080p. As opposed to creating full profiles, a single hot key for this would be awesome.

I got some HDR black level video testers, so I will sit down there later and see if I need to adjust the gamma setting.

one way is by creating a 2 profile and adding a hotkey to the profiles.

Ok, so my black levels were definitely being CRUSHED!

I used the following videos as tests: https://drive.google.com/drive/folde...95S7ck0tvR4yUM

Even WITH the gamma turned on, the lowest number I can see is 76 (with reference black being 64).

What display are you using and what playback software? Also, do you have madVR set to output full range and your desktop set to limited? If not, give that a try.

MPC-HC (the version still being updated).

I did attempt to set the computer to limited output (with madvr at full) - no difference on the black levels, just a washed out look to the screen.

Display is a Sony 285ES Projector.

So, I played the test clip in MPV Player, and I can see all the way down to the 68 black bar.

So this is definitely something in madvr, not my display etc.

The picture isn't as 'sharp', but also no noise/grain effect on mpv player. And the lighting level (as you may imagine with the black bar test) looks great.

Are you using LAV filters for video decoding? If so, make sure your RGB output levels are set to Untouched. While you're at it, select D3D11 for your hardware decoder to use and Automatic (Native) for hardware device to use.

the RGB output option doesn't do anything for madVR just leave them at default

Doesn't use madVR 2.20 as the default gamma? I don't understand why setting the same produces any change. Has this been changed in latest builds?

[huhn]

it doesn't use 2.2 is expect to be the norm this has no effect on calibration if you know what you are doing and this means it wouldn't change the image if you set it as 2.2 and just leave it as it is.

[LordX2]

Checking the gamma box for 2.2 did help me.

But the fact that mpv player shows more of the blacks instead of crushing them means there is something not right with my madvr settings somewhere. It's not the display or windows settings.

I don't know enough about this stuff to even know where to begin looking in the settings.

[huhn]

make a screenshoot control print i tell you if madVR is clipping.
just setting this display is calibrated to gamma 2.2 is supposed to do nothing on it's own

UPDATE:

Setting my Nvidia control panel to Limited output solved this issue.

At first, it looked totally washed out - but I had to reduce the 'brightness' on my projector. Once I adjusted it so it didn't have the washout effect, I reloaded the black level video and sure enough - I can see all the levels the same as with MPV Player.

Turns out, MPV Player automatically was putting out the limited range, which was why I was noticing a difference between the two players.

You can also set madVR to output as limited range if you wanted to keep your projector settings the same.

Interestingly, switching madvr to limited resulted in the 'washed out' screen as well, and I would have to adjust my brightness. MPV Player didn't - so who knows what is different between the two. But madvr is the one I want to use always, and I only use the PC for movies and shows, so I have no problem with the 'updated' projector settings.

My only concern is that I had to turn down the brightness, so I wonder how much of an impact that will have on overall brightness for movies.

Is that where the contrast recovery curves come in? Or is overall brightness only really adjusted through the peak and dynamic NITS settings?

[huhn]

just make a screen with madVR in full range and i can tell if it is clipping black levels.

Good to know.

[LordX2]

Another Update:

I was randomly looking through my projector settings, and I happened to see HDMI range. So I looked, and it was set to full range, so I decided to switch it to Limited Range to match the HTPC output.

Lo and behold, that was it.... after setting that, I was able to increase my brightness level on the projector back to where it was before with NO washed out effect.

Ran the black level video again, seeing all levels as I should.

I feel like I am in a video game where you enter a room with different symbols, and you have to randomly match the right symbols together to open a door or something....

I THINK I have finally found the right combination! Bright, excellent colors, great black levels, and all the madvr processing I can jam out of my 1650 Super!

So the solution to my black level issue was to set the Nvidia output to Limited as WELL as my projector HDMI input to Limited.

Just make sure madvr is set to full. You may want to try setting madvr to limited, gpu full, pj limited. You may or may not like that better.
