A subtitle is a textual representation of spoken dialogue or narration in a film, television show, or video. It appears at the bottom of the screen and helps viewers understand the content, especially when the audio is unclear or in a different language. Subtitles can also provide additional context, such as sound effects or music cues. Subtitles are often used in conjunction with closed captions, which include descriptions of non-dialogue audio elements for the hearing impaired. They can be found in various formats, including SRT and VTT, and are essential for making media accessible to a wider audience.
