Input and output requirements

Supported inputs

AWS Elemental Live can work with the supported color space in all supported types of input with the following notes:

  • Handling Elemental Link inputs: MediaLive can't read the color space metadata in a source from an AWS Elemental Link device. The workaround when you set up the input is to specify the color space that applies, as described in Scenario B – Metadata can be corrected with force.

  • Converting to Dolby Vision 8.1:

    • The video source must be HD or 4K resolution. In other words, the source must be 1080p or better.

    • The video source must be HDR10. If MediaLive encounters a portion of non-HDR10 content, it passes through the color space and color space metadata for that portion,

    • The video source can't be a file. This means that the source can't be a VOD asset in an MP4 file or a VOD asset in a transport stream.

    These constraints are stipulated by Dolby Vision 8.1, and relate to the minimal video quality required to produce Dolby Vision 8.1 outputs that meet the Dolby Vision 8.1 standard.
