The clip you see above this text is from the music video I'm Afraid of Americans, featuring David Bowie and Kurt Reznor. Movavi software. Double exposure. One track in the timeline in mono, the other in color with the background removed. A delay between the tracks. A collapsing blocks transition. 

What you see below this text is the same clip in half speed and reverse. It better illustrates the technique used. Both videos have the same looking opening credits. There are, in fact, two video clips here.
