Web Video Text Tracks (WebVTT) are text tracks providing specific text "cues" that are time-aligned with other media, such as video or audio tracks. The WebVTT API provides functionality to define and manipulate these text tracks. The WebVTT API is primarily used for displaying subtitles or captions that overlay with video content, but it has other uses: providing chapter information for easier navigation and generic metadata that needs to be time-aligned with audio or video content.
