Funny that someone would go though the effort of creating this, which likely took a bit of time, without bothering to find out how a Chinook actually flies
Actually, it's all about frame rate.
Even a minute variation in rotor RPM between the front and back rotors could produce the effect where one or other appeared to be moving in the opposite sense to actual.
Watch any film or video of a helicopter in flight and it's very difficult to discern the direction of rotation from successive frames.
