Specify how MediaConvert maps brightness and colors from your HDR input to your SDR output. The mode that you select
represents a creative choice, with different tradeoffs in the details and tones of your output. To maintain details
in bright or saturated areas of your output: Choose Preserve details. For some sources, your SDR output may look less
bright and less saturated when compared to your HDR source. MediaConvert automatically applies this mode for HLG
sources, regardless of your choice. For a bright and saturated output: Choose Vibrant. We recommend that you choose
this mode when any of your source content is HDR10, and for the best results when it is mastered for 1000 nits. You
may notice loss of details in bright or saturated areas of your output. HDR to SDR tone mapping has no effect when
your input is SDR.
