The new Phantom v1610 from Vision Research has broken the record for the most extreme slow motion camera ever created. It can record up to 1 million frames per second (FPS). Most films you watch are recorded at between 24 fps and 30 fps.
If you think about it in terms of videos being a series of pictures, your normal video camera would be able to take 30 photos in one second. This camera would take 1 million in the same timeframe. That means that if you played back the recording at a normal speed of 24-30fps, you could spend hours watching just one second of footage! Do you want one? It'll only set you back $100,000.
