Captioning is the process of adding written text to a video or film to provide a visual representation of the spoken language and other relevant audio elements, such as music and sound effects. Captions are typically placed at the bottom of the screen and are synchronized with the audio.
Captioning is used to provide accessibility to individuals who are deaf or hard of hearing, as well as to people who are watching the video in a noisy environment or in a location where they cannot listen to the audio. Captioning can also be useful for individuals who are learning a new language or who have difficulty processing spoken language.
There are two types of captions: open captions and closed captions. Open captions are permanently embedded in the video and cannot be turned off, while closed captions can be turned on or off by the viewer. Closed captions are typically provided in a separate file, which can be turned on through the viewer’s settings or by using a remote control.
Captioning is commonly used in various contexts, including television, movies, online videos, and educational content. It can also be used for live events, such as webinars or conferences. Captioning can improve accessibility and provide a more inclusive viewing experience for all viewers.
