HDR Tools filter in Motion

Use the HDR Tools filter to manually convert HDR or SDR images, clips, or Motion objects from one color space to another or to set the luminance (nits) of a video clip to a specific level.

The HDR Tools filters is best used in Standard Gamut SDR projects or Wide Gamut HDR projects. It’s not recommended for use in Automatic projects, where the color space of your media is automatically managed. (Applying the HDR Tools filter in an Automatic project has an additive effect to any existing conversion.)

Adjust this filter using the parameter controls in the Filters Inspector:

  • Mode: Sets one of nine color space options:

    • SDR to 100% HDR (HLG): Converts Rec. 709 SDR media to full HDR HLG luminance levels.

    • SDR to 75% HDR (HLG): Converts Rec. 709 SDR media to partial HDR HLG luminance levels.

    • SDR to HDR (PQ): Converts Rec. 709 SDR media to full HDR PQ luminance levels.

    • HLG to Rec. 709 SDR: Converts HLG media to Rec. 709 SDR luminance levels.

    • PQ to Rec. 709 SDR: Converts PQ media to Rec. 709 SDR luminance levels.

    • HLG to PQ (Rec. 2100): Converts HLG media to PQ luminance levels. 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): Converts PQ media to HLG luminance levels. 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.

    • HDR to Rec. 709 SDR: Converts HDR media (such as PQ, HLG, or log media that has been color-corrected in HDR) to Rec. 709 SDR luminance levels.

    • PQ Output Tone Map: Reduces the brightness of PQ media 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.

    Note: For some modes, such as SDR to 100% HDR (HLG), further adjustments to the image may be necessary to fine-tune the look.

  • Peak Brightness: For some Mode settings, this slider becomes available. Sets the nominal peak luminance of a display or sets a clip’s maximum luminance on a display to a specific level:

    • When Mode is set to SDR to HDR (PQ), this slider sets the nominal peak luminance of the (HDR) display on which the SDR content is displayed. For example, if you want to convert an SDR clip to HDR PQ and want the resulting PQ clip to look identical to an HDR clip on a 1000-nit display, set the Peak Brightness slider to 1000.

    • When Mode is set to PQ to Rec. 709 SDR, this slider sets the peak input level of the PQ media being converted to Rec. 709 SDR luminance levels. To avoid clipping, set the Peak Brightness to match the peak levels of the PQ media you’re converting. For example, if you apply this conversion to a PQ clip graded at 2,000 nits, everything above 1,000 nits will be clipped in the conversion. To retain and tone map the highlight detail into the Rec. 709 SDR color space, set Peak Brightness to 2000.

      Note: PQ to SDR conversions are limited to a maximum input of 5,000 nits using the HDR Tools filter.

    • When Mode is set to HLG to PQ (Rec. 2100) or PQ to HLG (Rec. 2100), this slider sets 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.

    • When Mode is set to PQ Output Tone Map, this slider limits the clip’s peak luminance. For example, if you want to limit your clip to 1,000 nits, set Peak Brightness 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%.
