Screencast: HTML5 <video> support with multiple files using Media Derivatives API

Have you seen my previous screencast (Intro in Derivatives API)?

In this screencast I show how to easily support HTML5 <video> tag on all major browsers using two derivatives of source video, created by Derivatives API. This is a sample feature. It's purpuse is to show how Media Derivatives API works and should not be used in production envirnonment.
