Types of Video Captions

    • Closed Captions are optional; they can be turned on or off with video controls. Videos with closed captions will have double CC icon. If you use closed captions, keep in mind, users who want access to closed captions will need to know how to turn them on, so it is important to include instructions for users. 
    • Open Captions are always displayed because it is part of the video stream. Users don't have to know how to turn these captions on. 
    • Audio Descriptions provide users with sound descriptions, such as "door creaking", and they give a better experience. 
    • Real-time Captions used for live events or sessions. These services are separate from Blackboard. There is typically a cost for this service and would need to be arranged prior to event or session. 
    • Subtitles translate spoken dialog, usually translated into a different language, and don't include audio descriptions. Subtitles assume that the user can see and hear.
