  If you want to add subtitles to a video on a web page, have a look at the HTML5 'track' element. It allows adding subtitles without muxing them into the video container.

  <p>WebM doesn't support subtitles nor chapters right now so you won't be able to embed them without creating a WebM file that is out of specs.
  You will probably want to remux your video into mkv and then convert your VTT subtitles to SRT and mux these into your mkv aswell.</p>

  <p>Is it possible to embed this two webVTT file in the webm in order to get only one file ?
  webm is a derivative of Matroska, so it's certainly possible. The real question is they will be handled by a program like VLC ?</p>
