Repeats: Sets the number of times the gradient repeats over the course of its range.
Repeat Method: Sets the method by which the gradient is mapped when repeating.
Values can be set to Mirror (default) or Wrap. This parameter affects the filter when
Repeats is set to a number greater than 1.
Map Channel: Sets the channel used to determine how the image is colorized. Values
can be selected from the following: Luminance (default), Red, Green, Blue, or Alpha.
Mix: Sets the percentage of the original image that’s blended with the color-corrected
image.
HDR Tools filter in Motion
You can use the HDR Tools filter to convert wide-gamut HDR media from one color space
to another or to limit the brightness of a video to a specific level.
Adjust this filter using the parameter controls in the Filters Inspector:
Mode: Sets one of four color space options:
HDR to Rec. 709 SDR: Converts high-dynamic-range (HDR) media (such as PQ, HLG,
or log media that has been color-corrected in HDR) to Rec. 709 standard-dynamic-
range (SDR) luminance levels. Further adjustments to the image may be necessary
to fine-tune the look.
PQ Output Tone Map: Reduces the brightness of PQ media down to the level you
set in the Peak Brightness slider (described below), and applies a soft rolloff to the
highlights so they don’t clip abruptly. Use this setting in PQ projects only, and apply
it as the last effect.
HLG to PQ (Rec. 2100): Maintains the brightness at a level you set in the Peak
Brightness slider (in accordance with Rec. ITU-R BT.2100-1) when applied to HLG
media in PQ projects.
PQ to HLG (Rec. 2100): Maintains the brightness at a level you set in the Peak
Brightness slider (in accordance with Rec. ITU-R BT.2100-1) when applied to PQ
media in HLG projects.
Peak Brightness: Depending on the Mode parameter setting, sets a clip’s maximum
luminance on a display to a specific level or sets the nominal peak luminance of a
display:
When Mode is set to PQ Output Tone Map, specifies the number of nits to which the
output of the filter is limited. For example, if you want to limit your clip to 1,000 nits
peak, set Peak Brightness to 1000.
When Mode is set to HLG to PQ (Rec. 2100) or PQ to HLG (Rec. 2100), specifies the
nominal peak luminance of the (HLG) display on which the HLG content is displayed.
For example, if you want to convert an HLG clip to PQ and want the resulting PQ
clip to look identical to an HLG clip on a 1000-nit display, set the Peak Brightness
parameter to 1000.
Mix: Sets the percentage of the original image that’s blended with the color-corrected
image. For the most accurate results when using the HDR Tools filter, keep this setting
at 100%.
