5. Click the Mode pop-up menu in the HDR Tools section of the inspector, then choose
one of the following settings.
Note: The first three settings in the menu may require further adjustments to the image
to fine-tune the look. For best results, arrange the order of the effects so that the HDR
Tools effect is applied after your color correction effects. See Change clip effect order
in Final Cut Pro.
• HDR to Rec. 709 SDR: Apply this generic conversion setting to any HDR clips in
Rec. 709 projects to convert the clips to Rec. 709 standard-dynamic-range (SDR)
luminance levels. For the best results, determine whether the clips are HLG or PQ
variants of HDR, then use one of the more specific conversion options below.
• HLG to Rec. 709 SDR: Apply this setting to HLG HDR clips in Rec. 709 projects to
convert the clips to Rec. 709 SDR luminance levels.
• PQ to Rec. 709 SDR: Apply this setting to PQ HDR clips in Rec. 709 projects to
convert the clips to Rec. 709 SDR luminance levels.
• PQ Output Tone Map: Apply this setting to reduce the brightness of PQ clips down
to the level you set in the “Peak Brightness (nits)” slider, and to apply a soft rolloff
to the highlights so that they don’t clip abruptly. Use this setting in PQ projects only,
and apply it as the last effect.
• HLG to PQ (Rec. 2100): Apply this setting to HLG clips in PQ projects to convert the
clips from HLG to PQ. This setting results in PQ clips that appear on PQ displays
identically to how the HLG clips would appear on an HLG display. The conversion
uses the HLG reference OOTF in accordance with Rec. ITU-R BT.2100-1, with peak
luminance corresponding to the level you set in the “Peak Brightness (nits)” slider.
• PQ to HLG (Rec. 2100): Apply this setting to PQ clips in HLG projects to convert the
clips from PQ to HLG. This setting results in HLG clips that appear on HLG displays
identically to how the PQ clips would appear on a PQ display. This conversion
uses the HLG inverse OOTF in accordance with Rec. ITU-R BT.2100-1, with peak
luminance corresponding to the level you set in the “Peak Brightness (nits)” slider.
6. To set a clip’s maximum luminance on a display to a specific level, drag the “Peak
Brightness (nits)” slider, for example, to 1000 nits.
7. To optionally set the amount of the original image to be blended with the adjusted
image, drag the Mix slider.
