Amazon Elastic Transcoder Adds Support for Closed Captioning Standard Typically Used by Digital Television

You can now use Amazon Elastic Transcoder to embed CEA-708 captions in the H.264 Supplemental Enhancement Information (SEI) user data in any MP4 or MPEG-TS output format. This allows you to deliver closed captions to televisions or to legacy iOS devices via HLS.

You can try this feature by choosing the “cea-708” option as the Caption Format when creating a transcoding job. For more information, see Captions in the Elastic Transcoder Developer Guide. There are no additional charges for using CEA-708 captions with your output formats.
