Format Support by Output Container - AWS Elemental Live

This is version 2.18 of the AWS Elemental Live documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Live and AWS Elemental Statmux Documentation.

Format Support by Output Container

There are several factors that control your ability to include captions of a specific format in your outputs. The factors that control this ability are:

    • The type of input container. A given input container can contain captions in some formats and not in others.

    • The format of the input captions. A given format of captions can be converted to some formats and not to others.

    • The type of output containers. A given output container supports some captions formats and not others.

    For example, if your input container is an MP4 container and your output is HLS and you want to include Web-VTT captions in the HLS output, you can do so if the MP4 container holds 608 embedded captions. But you cannot include Web-VTT captions if the MP4 container holds ancillary captions.

    For complete information about all the supported combinations of input container, input format, and output container, see Reference: Supported Captions.
