most likely just the film speed of the camera was just right to make it look as though the weren't moving just as it looks when you see a tire in a movie spinning backwards. Its extremely rare but possible

but the speed of the blades would change as the helicopter changed altitude and moved back and forth.

They are moving, you can hear them for one. They are in harmonic with the cameras refresh rate.

Yeah, it's the same deal as when a car's wheels can look stationary at a given speed. Notice also that the tail rotor looks to be rotating because it is not at the speed of the main rotor.

As far at the main rotor changing speeds, probably not occurring too much, nothing a little video editing couldn't fix...

Or hey, maybe it's magic

It's got to be the camera speed, or else that tail rotor wouldn't have any real torque to counteract... would spin that chopper like nothing else. Plus, the tail rotor is driven by the main rotor via gear drive, so it's hard to imagine one rotating without the other... (you can see the tail rotor since it's spinning way faster than the main). I'm pretty sure that heli has a rotor speed governer to keep the rotors at the same speed no matter what it's doing

That does look pretty badass though

Maybe it's some sort of new military helicoptor with another engine to power it in case the rotors stop spinning for some reason. Or, like others have said, it's the camera's refresh rate.

Surrender the booty, and let me get my hands on that beautiful treasure chest!!

One of these days, I'll actually buy a bike again...
