Aspen video player

What is the Aspen video player on top of the banner video. I mean this “Video stack placeholder” on Aspen features page. I can’t figure out how it is made.

At a guess I’d say it’s an image. I remember one or two of Nick’s video stacks require you to create an image to use as a placeholder. When the visitor clicks ‘play’ the video starts.

Yes, it seems to be an image. But in the Aspen theme example project there is no video player attached to it. I’m trying to find out how he has made that demo-page.
