Motion Extraction

Posy explains and demonstrates motion extraction, a video technique that overlays an inverted, time-delayed copy of footage on itself so only the changes between frames show. The video walks through the idea and shows the odd, beautiful results on ordinary scenes.

HN admires it as high-effort, well-produced work and a simple trick that makes slight motion visible.

“He's got some of the highest production quality YouTube has to offer. High effort content.”
