When you convert a video from one color space to another, AWS Elemental MediaConvert automatically maps colors from your input color space to your output color space. To optionally specify your own custom color mapping, use 3D LUTs (3D lookup tables).
3D LUTs contain color mapping information for a specific input or set of inputs. You receive 3D LUTs as .cube files from your color grader as part of your video production workflow.
