Falling Water Frozen in Mid-Air with the Help of Frame Rate Trickery

When recording video, a camera’s frame rate can produce some pretty strange effects. If matched up with a helicopter’s blades, a helicopter looks like it’s hovering in midair with motionless blades. YouTube user mrbibio found that the same thing can be done with falling water. His technique is brilliant: by pressing a water tube against a speaker, mrbibio was able to control the vibration frequency of the water flowing through the tube. He then adjusted the pulses of the water to match up with the frame rate of his Canon 5D Mark II. The result is a video of the water looking as though it’s frozen in time.

Strange Effect When Shooting Bass Player with a Canon 5D Mark II

urbanscreen discovered this strange string-wobble effect when shooting a bass player with a Canon 5D Mark II. No special effects or slow motion were added to the footage — what you see results from the frequency of the strings and the fast shutter speed of the camera. Here’s another video showing the same effect from different angles.

Can anyone explain what’s going on here?
