AWS Elemental MediaConvert has added support for HDR10+ metadata analysis and insertion. HDR10+ is a technology that further enhances HDR video with dynamic color metadata for viewing devices to adjust automatically on a scene-by-scene basis. Using MediaConvert you now have the option to perform a HDR10+ analysis on your HDR10 content and then to insert the resulting metadata into the encoded outputs for consumption on HDR10+ enabled devices. This metadata is treated like an enhancement layer to the base HDR10 metadata and allows for backwards compatibility with HDR10 compliant devices.
