When you take into account that the subsequent Apollo landings were shot at 30 frames per second, then to fake those would be three times harder. And the flag still isn't moving anyway. At the time of the broadcast, magnetic disk recorders capable of storing slow motion footage could only capture 30 seconds in total , for a playback of 90 seconds of slow motion video. If we apply this to 12 frames per second film as close to ten as we can get with standard film running for minutes this is how long the Apollo 11 footage lasts , you would need six and a half reels. That said, the sun isn't the only source of illumination — light is reflected from the ground too. Well, maybe they did have a super secret extra storage recorder — but one almost 3, times more advanced? When this is played back at the normal frame rate, this footage plays back for longer.
