<div class="imvdb-embed" data-embed-type="video" data-id="603951594623" data-include-credits="y"></div>
Wordpress shortcode:

Requires the Wordpress plugin.
You can find all the embed customization options here.
If you are using the manual code, you'll need to include this code once before the closing body tag of your site.
