How We Make Slow Motion Sounds

In this episode of Smarter Every Day, Destin Sandlin explores a problem most people never think about: when footage is shot at extremely high frame rates, the camera can’t capture usable sound. The result is that many slow-motion videos rely on recreated audio instead of the real thing. Using an exploding tomato as an example, we walk through how we build convincing audio from scratch, layering impacts, debris, and textures to match what you would expect to hear, even if it doesn't exist.
