Reference: Supported Captions

This document is intended to ensure that when creating an event or profile, you select a format that is valid for your output captions.

Various constraints exist for the caption formats that you can include in your content:

  • For a given input container, AWS Elemental Live can parse certain caption formats.

  • For a given input caption format, AWS Elemental Live can create one or more output captions. However, a given output caption can appear only in specific output containers.

In summary – starting with the output container you want to produce:

  • A given output container supports a given set of output caption formats. This container constrains your choice of output captions.

  • Furthermore, to produce each output caption format, you must use one of the compatible input caption formats .And you must select an input caption format which can appear in the input container you have selected. So both which original input container and format you choose constrains your choice of output caption formats.
