I have been trying to figure out what this all means and how to use them:
- Color space under Project/Movie settings;
- Color Space Correction under Effects, Movie Settings;
- Instruments Meter settings - Global settings, Norm and Waveform Monitor - Display 7.5 IRE black level (NTSC).
Recently, Magix introduced (18.104.22.168):
"HDR preview and color space handling: You can now select HDR, Full HD/UHD or SD as color space for your project in Video Pro X. New options for color space within the program allow you to visualize the finest nuances of color and ranges in contrast. Experience enhanced visual control and precision in your color correction workflow."
From what I can tell, this new feature is under Project Settings/Movie Settings:
This was not in 22.214.171.124. The options are BT.601, BT.709 and BT.2020, corresponding to SD, Full HD/UHD and HDR. order). Definition from Wikipedia: "BT.2020, defines various aspects of ultra-high-definition television (UHDTV) with standard dynamic range (SDR) and wide color gamut (WCG), including picture resolutions, frame rates with progressive scan, bit depths, color primaries, RGB and luma-chroma color representations, chroma subsamplings, and an opto-electronic transfer function."
Q1: Thus, UHD is BT.2020 is it not? Thus for a 4K (or higher) project, one should select BT.2020.
Q2: Then what should be selected for HDR?
We also have under Meter Settings:
Note that there is no BT.2020.
Q3: Did Magix forget to include this?
I am on NTSC, so I turn on the Display 7.5 IRE Black. This gives the Waveform shown below:
This range of 7.5 to 100 corresponds to levels between 16 and 235 on the right hand side. For Legal TV levels, it is said that one should keep the blacks above 7.5 (16) and the whites below 100 (235) or they or any detail in those ranges will be crushed. Thus, one should raise the bottom levels using the RGB curve such that nothing goes below 7.5, and lower the upper right of the curve so that nothing is above 100 (235).
Q4: Is this correct?
Q5: Does this also apply to European TV's?
Under Effects/Movie Settings - Color Space Correction:
It appears that this is connected to the Waveform Instrument. As soon as this is checked, then the Waveform becomes limited to between 7.5 and 100, thus there is no need to adjust the bottom and top of the RBG curve.
Q6: Is this correct?
I noticed that the Effects/Movie Settings - Color Space Correction can be turned off and on using the blue lightning button for quick comparison.
Here is with the Color Space Correction unchecked (or rather on but blue lightning button on) - blacks and whites below 7.5 and above 100:
Here is with the Color Space Correction unchecked (or rather on with blue lightning button off) - blacks and whites limited to between 7.5 and 100:
This looks a bit faded compared to the original.
Turning on Auto Color also turns on Auto Exposure (I hadn't noticed this before) and seems, in this case, to get better contrast.
Q7: Overall, is this the setup that I should be using?
