Captioning and Described Video

Captioning is the process of converting the audio content of a video into text captions that are displayed at the bottom of the screen. Closed captions can only be viewed when specifically enabled, while open captions are permanently displayed throughout the video.

Described video is a technique used to add context to an audiovisual recording by narrating the visual elements.
