Speed up video in Storyline?

This piece of Javascript speeds up all your videos. Or slows it down..depending on your code..

var videos =document.querySelectorAll('video');
for (var i=0;i<videos.length;i++)
{
videos[i].playbackRate = 5;
}

Keep in mind though that DS-bootstrap on which Storyline is based has some limits on the amount of speeding up media-elements. I noticed using up to 15x works, and when trying to speed up to 25x you get a error-message from DS-bootstrap that your speed is too high ;-)
