No video id in HTML embed?

I was originally trying to follow pixelgeeks process for overlaying a movie video ontop of a product in your CMS listing. My goal is to have a hover so that when you hover over the product, a video/gif plays of that same item rotating.

I’ve tried following this tutorial below

but to no avail, i cannot seem to find any sort of video id element in the HTML code embed leaving me stuck in the sand on this one. Can anyone help me on this? I’m terrible with coding, but given directions, i can easily follow along.

The website as it currently looks is bare bones. I’ve yet to swap out a lot of content, but im getting product information in when i was attempting to do this.
