what is vtt file

A VTT file is a text file saved in the Web Video Text Tracks (WebVTT) format. It contains supplementary information about a web video, including subtitles, captions, descriptions, chapters, and metadata. VTT files do not contain any video data. The WebVTT format is designed to provide chapters for content navigation, text video descriptions, and other metadata aligned with audio or video content. VTT files are compatible with most major media hosting platforms and can be used to caption or subtitle videos on platforms like YouTube, Vimeo, and VideoLAN VLC Media Player. VTT files can be opened and edited using any text editor, such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or GitHub Atom (multiplatform) . They can also be viewed by dragging the file into any web browser.
