The procedure for output handling - AWS Elemental MediaLive

The procedure for output handling

Follow this procedure to configure color space handling in each output. You can set up each output with different color space handling. For example, you can create one output that passes through the original color space, and another that converts it.

To get ready

You must decide if you need to enable enhanced VQ mode in the output. This mode applies only to outputs that use H.264. Follow these guidelines:

Planned conversion Details Action

Convert to SDR

You want to convert HDR content as well as SDR content.

For example, if you want to convert both 601 and HLG content to 709.

You must enable enhanced VQ mode.

Convert to SDR You don't want to convert any of the HDR content. You don't need to enable enhanced VQ mode.
Any action There is no HDR10 or HLG in any of the inputs. You don't need to enable enhanced VQ mode.
Any action You have already enabled enhanced VQ to improve the video quality. Leave the mode enabled.

To enable enhanced VQ mode, see Setting up enhanced VQ mode.

To set up each output

  1. On the Create channel page, in the Output groups section, choose the output.

  2. Display the Stream settings section, and choose the Video section.

  3. Complete the Width and Height fields to specify a valid resolution. Make a note of whether you are specifying an SD, an HD, or a UHD resolution.

  4. For Codec settings, choose H264 (AVC) or H265 (HEVC).

  5. If the resolution is an SD resolution, choose Codec details, and then complete the Profile, Tier (for H.265 only), and Level fields.

  6. If the resolution is an HD or UHD resolution, choose Codec details, and then complete Profile:

    • If you want to convert the content to an HDR color space, or if you want to pass through an HDR color space, choose one of the profiles that has 10BIT in the name.

    • If you want to convert the content to an SDR color space, or if you want to pass through an SDR color space, you can choose any profile.

  7. For Color space, choose Color space settings, and then choose the appropriate option to remove, pass through, or convert the color space metadata. For information about the options, see the tables later in this section.

  8. If you are converting to HDR10, you can optionally complete Max CLL and Max FALL to set display metadata. For details about a field on the MediaLive console, choose the Info link next to the field.
