Filter results for instagram videos only- instafeed.js

I am using the great and dead simple instafeed.js to pull a couple of my instagram videos into my personal webpage. It is working but I have not found an option for filtering results for just videos. Currently it shows a combination of images and videos. All I want for the return result is videos.

<script type="text/javascript">
  var feed = new Instafeed({
     limit: '10',
     sortBy: 'most-liked',
     resolution: 'standard_resolution',
     clientId: '467ede5a6b9b48ae8e03f4e2582aeeb3', 
     template:'<div class="tile"><div class="text"><b>{{likes}} &hearts; </b>{{model.user.full_name}}</div><img class="item" src="{{image}}"></div>'
  });
</script>

<div id="instafeed"></div>
