Step 3: Set up inputs to correct metadata

In the previous step, you identified how to correct color space metadata in each input. This section describes how to set up each input for the required correction.

Note

This section assumes that you are familiar with creating or editing a channel, as described in Creating a channel from scratch.

To set up each input attached to the channel

1. On the Create Channel page, in the Input attachments section, for Video selector, choose Video selector.

2. Set the appropriate values for Color space and Color space usage. See the table after this procedure.

3. This step applies only if you chose HDR10 and the attached input is for a MediaLive device such as AWS Elemental Link, and you plan to convert the content to another color space. You must specify the values for the Max CLL and Max FALL for the content. You should have obtained this information from the content provider.

   In the Max CLL field and the Max FALL field, enter the values.

In the following table, each row shows a valid combination of the two fields and the result of that combination.

Color space field	Color space usage field	Result
FOLLOW	This field is ignored.	Passthrough. MediaLive doesn't change the color space metadata.
REC_601 or REC_709 or HDR10 or HLG or Dolby Vision 8.1	Force	Cleanup. MediaLive marks all the content as using the specified color space.
REC_601 or REC_709 or HDR10 or HLG or Dolby Vision 8.1	Fallback	Cleanup. MediaLive marks the content as using the specified color space only for portions of the content that are unmarked or marked as unknown or marked with an unsupported color space.
