                          So instead of showing an actual knife you show computer graphics. So smart.

                            Not bad, pretty close. Actually it revolves around the shutter speed per second and the frames per second. Both must come into play for the blades to appear motionless. Frames and shutter speeds dont always match in cameras. Say the frames per sec in ur camera are 32 and shutter speed is 33 and the helo blades are rotating at 32 rotations per sec. The blades will appear slightly blurry and look as if their in supper slow motion rotating clockwise. Now if the blades and camera frames were at 33 per sec and ur shutter at 32 the helo blades would look. Slightly blurry in supper slow motion going counterclockwise.. Hope this helped. PS- regular helo & not a gov secret flight..

                                Try adjusting the shutter speed / frequency of the camera. Otherwise, adjust the speed of whatever is being captured.

                                                          Great video, but it's probably more accurate to say that the blades are moving at a much higher number of times per second that are evenly divisible by the frame rate. So, if the frame rate is 30, the RPM could be something like 300 or 330 RPM. ... or, even a number divisible by 1/6 since there are 6 blades on the heli, and the video could be "swapping out" blades to still give us that illusion. Just a guess.

It's the image sensor that refreshes however many times per second the video is recorded. In this she says the shutter is the one that is refreshing X times per second. Also why rolling shutter is named this I am uncertain because it actually doesn't have to do with the shutter. The 2 types of shutter are leaf and focal plane. This "rolling shutter" (which should be called progressive scanning instead) is not present in many cameras. CMOS sensors capture the entire frame as mentioned before by utilizing the entire image sensor at once. Therefore they do not suffer from this distortion. Also almost all cameras use a focal place shutter. It's essentially a curtain that moves very fast across the focal plane while another curtain follows behind it.
