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%.
