Closed captions provide text descriptions of the audio for audience members who cannot hear the audio (or hear it well). You can add closed captions to an on-demand presentation by creating closed caption files and linking them to the presentation. You can create the files yourself using third-party captioning software or you can use a captioning service. Your audience can search closed caption text in players and video collections for specific words and phrases.
Audio descriptions describe what is happening in the video allowing audience members who can't see the video (or see it well) understand what's happening. You can manually add audio descriptions to on-demand presentations linking audio description files to them.
If these features are not available in
your system, contact your Mediasite administrator. All player layouts support
presentations with closed captions added. However, audio descriptions are only
available in the MultiView player. Also, audio descriptions are not available in
Publish to Go presentations.

Considerations when adding closed captions
•Mediasite supports Synchronized Accessible Media Interchange (SAMI), SubRip (SRT), and Distribution Format Exchange Profile (DFXP).
•Sonic Foundry does not provide SAMI, SRT, or DFXP files or tools for authoring them.
•Non-English captions must be saved with UTF-8-character encodings.
•Mediasite supports begin and end times in DXFP so you can specify expiration times, that is, how long captions remain on screen.
•Captions are centered and appear directly below the video window even when player is enlarged.
