Great video, bad title!
Zoom AND move.
Moving changes the relationship of objects in the frame, zooming changes the crop. "Zoom with your feet" is good advice to a neophyte to break their feet loose from the ground, but it becomes bad advice after a while. Managing the relationship of objects in the frame is perhaps more important, but getting the crop right is as well.
(Says the guy who never puts a zoom lens on his camera, and generally shoots with a lens chosen at random..)
