6. In the HDR Content Light Level Metadata section of the inspector, enter values based
on the content of your program and the specifications of the target device.
If you’re not sure of the proper values to enter, leave the fields empty.
• MaxCLL (Maximum Content Light Level): Enter the level, in nits, of the brightest pixel
component in the program.
For example, if the peak brightness (maximum luminance) of the target television or
display is 1000 nits, you can apply the HDR Tools effect to the entire project, with
the effect configured to convert to a maximum Rec. 2020 PQ output level of 1000
nits. In this case, you would enter 1000 for MaxCLL. For more information about the
HDR Tools effect, see
Convert or adjust HDR clips in Final Cut Pro.
• MaxFALL (Maximum Frame Average Light Level): Enter the value, in nits, for the
frame in your program with the highest average brightness level.
7. If you know the characteristics of your mastering display (the reference monitor you use
tasks such as color correction that require maximum color and brightness accuracy),
enter the values in the HDR Mastering Display Metadata section.
For example, if you’re mastering with a Sony BVM-X300 monitor, you would enter the
following:
• Display Primaries: Rec. 2020
• Display White Point: D65
• Maximum Display Luminance: 1000
• Minimum Display Luminance: 0 or 0.0001
If you’re not sure of the proper values to enter, leave the fields empty.
8. Export the file.
HDR files require a 10-bit or higher codec, such as Apple ProRes.
Note: Check the “Color space” field in the Settings pane of the Share window before you
export to ensure that the project color space is set to Wide Gamut HDR - Rec. 2020 PQ.
