WebVTT is the “Web video text track” file format. You might think it’s just about captions and subtitles. But far from it: in HTML5 we’ve developed a comprehensive solution for any text-like data or events that occur relatively rarely along a video or audio element’s timeline, which also includes tracks for blind users. Most of the big browsers have by now implemented support for text tracks. We will look at captions, subtitles, video descriptions, and chapters, which all solve parts of the accessibility picture for HTML5 media and show you how you can make use of them.
