What are Closed Captions?

Closed captions are a type of subtitles that include additional interpretive information such as sound and tone descriptions (words that phonetically imitate/resemble sounds) for hearing impaired viewers.

If a video includes a Closed captions or Subtitles file, the Closed Caption icon will be displayed on the player controls.

Closed captions can be assigned to your video objects during the upload process either by uploading a file or linking it to an external link.

Note: You may upload multiple Closed captions and Subtitles files for different languages.
