The WebVTT (Web Video Text Tracks) file format is a text-based format used for displaying timed text tracks, such as subtitles, captions, descriptions, chapters, and metadata, in conjunction with HTML5 `<video>` elements. It is designed to be a simple and efficient way to add accessibility and enhance the user experience for online video content. WebVTT files are plain text files that contain cues, each consisting of a start time, an end time, and the text to be displayed during that time interval. The format supports styling options, allowing for customization of the text's appearance, including font, color, and position on the screen. WebVTT is a crucial component of modern web video accessibility, ensuring that content is accessible to a wider audience, including those who are deaf or hard of hearing. It also facilitates language localization by providing subtitles in multiple languages. The format is standardized and widely supported by web browsers and video players, making it a reliable choice for delivering timed text tracks.
