The flickering is just a function of how video works. You are actually being shown many still pictures that are changed at a certain rate (60 Hz typically). LED displays are also turning on and off to give you the video like look. If you film anything worth a slightly different refresh rate, you are taking still pictures 30, 60, out 120 times per second. Some of the pictures capture the display between refreshes while it is momentarily off. This shows up in the video as flickering.
There are videos of helicopters flying where it looks like the rotors are sitting still. This is nothing more than the rotational frequency of the rotor matching the refresh rate of the video. So every still frame in the video is basically taking a picture with the rotor in the same position.
