Can you convert a video to pure CSS?

He regularly shares cool examples of fancy css animations. At the time of writing his focus has been on css scroll animations. I guess there are some new properties that allow playing a css animation based on the scroll position. Apple has been using this on their marketing pages or so jhehy says. The property seems pretty powerful.

But how powerful?

This got me thinking... Could it play a video as pure css?
