The Difference Between Open and Closed Captions
Captions allow people who are deaf or hard of hearing to have complete access to video content. Captioning is the process of displaying timed text on a video to represent sounds such as dialogue, sound effects and descriptions of music and lyrics. You may have heard of captions before, but did you know that there are two types of captions?
Closed captions give viewers the option of switching the captions on or off while watching a video. They are the most common form of captioning and can be identified by the [CC] symbol. Closed captions can only be displayed when the media player or video sharing site (e.g. YouTube or Vimeo) being used supports it.
Open captions, also known as burned-in, baked on or hard-coded captions, are seen by everyone who watches the video. Open captions are a permanent feature on the video and can’t be turned on and off. Open captions are often used for videos which are being played on website video players that don’t have closed captioning functionality.
Where Are They Used?
Closed captions are most commonly used on television and sites like Facebook, YouTube and Vimeo. The closed captions option can also be found on many DVDs and can be turned on in the menu.
