That's what one commenter on the site said it probably was. Very professional looking and deliberately without sound as a studio would supply its own soundtrack. The equivalent of all the helicopter panoramic shots we've grown used to over the last 40 years in movies.
It might have been filmed for background for “in car” movie scenes but it could be used today to reconstruct the entire neighborhood if someone needed it done. At least the “front” of them like in a lot of old westerns.
