1.2.2 Captions (Prerecorded): Captions are provided for all prerecorded audio content in synchronized media, except when the media is a media alternative for text and is clearly labeled as such. (Level A)
This success criterion intends to provide captions for all the videos that have audio in the form of dialogues, voiceover and other sound clues that combinedly convey information or help to understand the video. Captions, also known as subtitles or CC (Closed caption) in abbreviated form are most helpful for deaf, hard of hearing, deaf blind & users who don’t follow the video and depend on captions. Captions include not only the dialogue but also information such as speaker & non-speech information conveyed through sound which is meaningful like the claps of audience and laughter.
