Gorgeous demo of iPhone 5s slow-motion video capabilities
Normal video is shot at 30 frames per second, a rate fast enough that the action looks smooth to the human eye. By filming at 120fps, four times faster than normal, the footage still looks beautifully smooth when slowed down by the same amount.
The effect was used in footage shot at the Burberry London fashion show, shot entirely with the iPhone 5s.
