Well, I just looked at the vid. It is not the one I thought it was, which was quick and brutish! The one I intended was only about bead breaking, having nothing to do with bead seating. I do see the guy standing in the middle of the rim. What a fool!

What I had intended to show was the simple process of using a piece of sturdy angle iron, say 1/4" X 2" and a sledge hammer. The application is simple. Deflate the tire(!). Set one edge of a 2-3" long piece of angle iron at the intersection of the rim and bead with the convex side of the angle iron up and the other edge over the tire. Beat the angle iron being careful not to hit the rim, bead broken.

My apologies for inserting the wrong vid. Operator error. I'll do better next time.
