heres the explanation for it if you don't get it:
video cameras are actually just a quick run through of photographs taken wiht very short intervals. therefore, your video camera has a frame rate of 30 frames a second. therefore, it takes 30 'pictures' every second. now if a helicopter span at any MULTIPLE of that 30 (30, 60, 300, 900) that would mean that every 'picture' that was taken by the video camera would have the blades in the exact same position, meaning they have spun around exactly a certain amount of times (ending up in the same position) before the video camera shot its next 'picture'.
