title: How to get a Vimeo external link
body: <p>To embed a Vimeo video as a background video, I see in this code pen:</p>
  
  <p><a href="https://codepen.io/BRacicot/pen/JpLmqo" rel="noreferrer">https://codepen.io/BRacicot/pen/JpLmqo</a></p>
  
  <p>that video source url is an special type with "external" word:</p>
  
  <pre><code>https://player.vimeo.com/external/243924757.hd.mp4?s=1fc7fe8bd116cdd9c9c3e639ddbae75f2f4f8f2e&amp;profile_id=174
