Specify the color space you want for this output. The service supports conversion between HDR formats, between SDR
formats, from SDR to HDR, and from HDR to SDR. SDR to HDR conversion doesn't upgrade the dynamic range. The converted
video has an HDR format, but visually appears the same as an unconverted output. HDR to SDR conversion uses tone
mapping to approximate the outcome of manually regrading from HDR to SDR. When you specify an output color space,
MediaConvert uses the following color space metadata, which includes color primaries, transfer characteristics, and
matrix coefficients: HDR 10: BT.2020, PQ, BT.2020 non-constant HLG 2020: BT.2020, HLG, BT.2020 non-constant P3DCI
(Theater): DCIP3, SMPTE 428M, BT.709 P3D65 (SDR): Display P3, sRGB, BT.709 P3D65 (HDR): Display P3, PQ, BT.709
