Closed Captions

What are Closed Captions?

Closed captions are text versions of the spoken part of a television show, movie, or video. These captions are usually shown at the bottom of the screen. They can be turned on or off by the viewer, hence the term "closed." These captions are essential for people who are deaf or hard of hearing as they allow them to understand what is being said. Moreover, they are also useful for viewers who wish to watch videos without sound or are trying to learn a new language.

Why are Closed Captions Important?

Closed captions play a crucial role in making videos accessible to a wider audience, including:

• Helping people who are deaf or hard of hearing to follow along with audio.
• Aiding those learning a new language by allowing them to read and listen simultaneously.
• Enhancing understanding when the video audio is unclear or when watching in a noisy environment.

How Do Closed Captions Work?

Closed captions are added to videos through a process that involves several steps:

• Transcription: All audio content, such as dialogue and significant sound effects, are transcribed into text.
• Timing: The text is synchronized with the audio in the video, so it appears at the same time the words are spoken.
• Encoding: The text and timing information are encoded into the video file. The viewer can activate or deactivate the captions using their media player.

This process ensures that the captions are an accurate and timely representation of the audio content, providing access and enjoyment to all viewers.
