This is cool ...

It would be really cool if it looked like that to us in real life, but the 24FPS camera is what allows for the effects - frozen at 24Hz, slow forward at 25Hz, and slow reverse at 23Hz.
I think we process visual info at a "frame rate" of around 55-70 Hz.

This makes sense because the power frequency is set to 50Hz in Europe and 60 Hz in NA....we don't notice the flicker at those frequencies.

Have you ever used a timing light? That's very useful for checking the spray pattern in throttle body fuel injection when the injectors are exposed, like on a GM car or truck. If you used a DC power supply and an oscillator that's connected to the pickup, you could show this without a camera.

Yeah, that was my first thought when I saw the video was they were using a strobe light. But then I thought about what type of strobe light would be that effective outside in daylight and realized it was the camera frame rate producing the effect.

Probably, but a timing light is just as effective in sunlight because the Xenon bulb is extremely bright. The easy way to cause stop action is to record with lighting that uses AC- at 30 frames/sec and 60Hz AC, it's easy. At 24 fps/50Hz, it's close enough.
