VTT File Creation

A WebVTT (Web Video Text Tracks or .vtt) file contains a series of text cues with start and end times in the video. The text in these cues appears only when the video reaches the specified times.

JWX's players use .vtt files to associate side-loaded captions and add chapters with videos.
