Scenario C – Correct the metadata with fallback

During assessment of the MediaLive input, you might have determined the following:

  • Different portions of the content are in different color spaces. All those color spaces are supported.

  • The metadata for one color space is either inaccurate everywhere, or is sometimes accurate and sometimes inaccurate.

  • The metadata for content for all the other color spaces is accurate.

For example, the input has Rec. 601 content that has portions that are inaccurately marked. It also has portions that are missing, unknown, or unsupported. The input also has HDR10 content and HLG content that is accurately marked.

You have this option for handling the metadata in the output:

Correct the metadata

Follow the procedure in Set up inputs to correct metadata, and set the key fields as follows:

  • Color space field – Set to the color space that has inconsistent metadata (Rec. 601 in the above example).

  • Color space usage field – Set to FALLBACK

During ingest, MediaLive will create metadata of the specific color space for all missing, unmarked, and unknown video content. It won't change any supported color space metadata. (It will fall back to the existing metadata.) Therefore, it won't change the accurately marked Rec. 601 or the accurately marked HDR10 or HLG content.

After ingest, all the content in the input will be consistently marked, even though the content is in several color spaces.
