Subtitles are written versions of the dialogue and other spoken audio in a movie or television show that are displayed on the screen.
They are typically used to provide translations of the spoken audio for viewers who do not speak the language in which the movie or show is being spoken. Subtitles can also be used to provide translations of dialogue spoken in a different language or to provide captions for viewers who are deaf or hard of hearing.
Subtitles may be burned into the video itself, meaning that they are always visible and cannot be turned off. Alternatively, they may be displayed as a separate layer on top of the video, which allows the viewer to enable or disable them as needed.
Subtitles may also be displayed as closed captions, which can be turned on or off using the television's settings.
Subtitles can be helpful for a variety of reasons, including allowing viewers to understand spoken audio that is difficult to understand due to accents or background noise, providing translations for viewers who do not speak the language in which the movie or show is being spoken, and making movies and TV shows more accessible to deaf or hard of hearing viewers.
SRT and VTT are two different file formats that are commonly used to encode subtitles for movies and television shows. Both SRT and VTT files are plain text files that can be opened and edited using any text editor. They are typically used to encode subtitles in different languages, and they can be easily converted to other subtitle file formats using a variety of online tools or specialized software.
