The Trippy Visual Effects of Motion Extraction

YouTuber Posy has taken what seems like still scenes and shows us just the parts that move. He's termed this technique "motion extraction," and he explains exactly how he did it, and how you can, too. But this is more than just a tutorial, because even if you will never try this, you'll be amazed by watching these clips. First, we get scenes in which only the moving parts are shown, no matter how subtle, and then he overlays the motion extraction video with the original video to make the motion a highlight. From there, he does all kinds of effects to make the motion the centerpiece of the scene, no matter how small or slow the movement may be. The clips are all quite beautiful, except for maybe the one where the guy makes the building shake by walking across a wooden floor, but that one is interesting in its own way. -via Digg
