What is Closed Captions?

Closed captions are the text versions of the video or movie. Closed captions help the people who have hearing problems. Closed captions are the time synchronized text reflecting the audio track of the video and can be watched while watching the video. The audio of the video is transcribed and the divided into ‘caption frames.’ Then these are synchronized with the video. These are located underneath the video or on top of the video. The primary goal of closed captions is to expand the audience.

Difference between closed captions and subtitles

Captions are a text version of what is being spoken on the screen. They are not the translation into other languages. Captions can be open or closed.

These can be turned on or off. Open captions are part of the video and cannot be turned off. On the other hand, subtitles are the translated text version of audio into another language. Subtitles assume that the viewer can hear the audio.

Apart from ensuring accessibility, captions also help the viewers to follow what is happening in the video when they cannot play it with sound in places such as hospitals or when they are in the noisy environment.

Subtitles were developed for viewers who do not speak the language that is used in the video. Both closed captions and subtitles are the tools for expanding the audience and increase viewer engagement.
