Derren Brown Predicts National Lottery Numbers How? Secrets Revealed at (http://www.myserving.co.uk/Derren)

That's why you can see the right screen moving? :L

There is a split screen down the centre of the frame. Derren and TV are on the right of the frame live... The left side of the split-screen cuts to a recording... that allows an assistant to run in and place the balls... Then switch-screen is turned off to do the reveal.

They are in numerical order. If an asistant is placing the balls as they are drawn they have 10 seconds to put them in order !

I just noticed something, there is a third camera, look very closly at Derren after he waves 0:52, he points to the TV and turns around then looks at the right at the first camera man and then quickly realizes that he is looking into the wrong camera and quickly changes his view to the motion controlled camera. The shot where he walks in and the view from the other camera, they have blocked out the crane camera, notice the other camera is static. (Con't Below)

Another quick note, the man holding the camera is stood right in front of Derren, look closely and it dosn't match the image when we go back, it slightly off to the right, which tallies up with what i wrote up top....
