Once a presentation is created, you will need to add closed captions. All Mediasite players will support presentations with closed captions. If your presentation was created with the CarmenZoom integration, the audio transcript will be imported with the recording and displayed as closed captions.
Add Closed Captions
Mediasite has an integrated automated transcription service, or you can manually upload a caption file.

Edit Closed Captions
Automated captions must be reviewed for accuracy. Closed captions generated with AI transcription tools do not meet the Minimum Digital Accessibility Standards for multimedia presentations. Captions generated with the automated transcription service must be reviewed for accuracy before the presentation can be considered accessible. Mediasite includes a built-in tool for editing your presentation's closed captions.

From within the list of presentations in your My Mediasite portal, select the name of the presentation for which you wish to edit the closed captions. A summary of the presentation will appear
