title: Can I set a video length limit on a HTML5 file upload?
body: <p>When uploading a video through a HTML5 input such as:</p>
  
  <p><code>&lt;input type="file" id="input"&gt;</code></p>
  
  <p>I know it is possible to set a limit on the file size using PHP / Node.Js. </p>
  
  <p>Is there a way to set a limit on the video length, not the file size? </p>
  
  <p>I.E: Only allow a user to upload videos which are 15 seconds or less. </p>
