• Replace the video link that you just created from:
   
  <a href="/kb_upload/file/video.mp4">/kb_upload/file/video.mp4</a>
  
  to:
   
  <video width="320" height="240" controls="controls">
      <source src="/kb_upload/file/video.mp4" type="video/mp4" />
      Your browser does not support the video tag.
  </video>
  
  Where video.mp4 is the name of your video file.  Use your own width and height values to suit, or you can remove the width and height altogether, or use only width or only height.
  
  For further information, see the W3C video tag specification.
