The youtuber Chris Chris caught the moment a helicopter starts to soar, the funny thing is that it seems to rise magically, without moving the blades.
What is the optical effect due to? The recording frequency of the camera coincides with the frequency of rotation of the helicopter blades.
The camera captures a frame with a certain number of turns of the blades, so that each blade is captured in a position equivalent to the previous one, giving the effect that it is magically ejected.
