Episode 228 of 792 episodes

Meet the “motion microscope,” a video-processing tool that plays up tiny changes in motion and color impossible to see with the naked eye. Video researcher Michael Rubinstein plays us clip after jaw-dropping clip showing how this tech can track an individual’s pulse and heartbeat simply from a piece of footage. Watch him re-create a conversation by amplifying the movements from sound waves bouncing off a bag of chips. The wow-inspiring and sinister applications of this tech you have to see to believe.
