Closed captions means that the captions are on a separate track that can be turned on or off, usually by pressing the “CC” button on the video player. See a complete list of closed caption profiles here. With open captions, the captions are burned into the video, so that they are always showing. Since open captions are part of the video itself, they provide the advantage of being supported by all video players and devices. Open captions eliminate rendering inconsistencies across different video players and allow publishers to control the exact size and style of the captions.
