1,000,000,000,000 FPS

It isn't actually shooting video at a trillion frames per second, in that it is not shooting one trillion frames. It's a camera with a shutter speed of 1/1,000,000,000,000th of a second capturing images rapidly which were collated into a video shown at a framerate a little more conducive to human eyes.

A second of video shot at a trillion frames per second would take centuries to view if slowed down to 30.
