What is the Difference Between Closed Captions and Subtitles?

closed captions and subtitles

Closed captions and subtitles help people understand videos better, but they're used differently. Closed captions are for people who can't hear well. They show not just what's said but also sounds like music and effects. They're added after a video is done and are made for those who need help hearing. They are typically added after the release of a film or TV show and are created based on the final audio mix.

On the other hand, subtitles are used for those who can hear the audio but may not understand the language spoken. Subtitles include only dialogue and are developed for audiences who need language translation. Subtitles are made before a video is released, especially for viewers who speak different languages.

Closed captions are more inclusive and comprehensive. Captions aim to assist viewers with hearing difficulties, while subtitles translate dialogue for those who speak different languages. If you want a fast and easy way to add closed captions to a video, an exceptional tool can do that.
