Me and a mate are pretty sure we've worked it out... Here goes:
1. It is obvious that he doesn't know what the numbers are before hand.
2. It is strange that he doesn't write down the numbers as they come up but instead waits for them all to finish and wastes quite a bit of time doing this.
3. The camera shakes around an awful lot and if you watch other channel 4 shows with their sophisticated mobile tripods it's easy to keep it more steady than this. These motions of the camera while he's doing it all are very slight the whole time and could very easily be done digitally.
Therefore... We reckon that it's like a split screen so the left half of the screen is solid (or looping a few seconds) while what actually happens is there is somebody there putting the balls onto the stand while he is voicing what balls to get to somebody else back stage. Then when he goes over the split screen thing is switched off and the camera is then controlled once more by a person zooming it in.
Bit weird why he introduces the fact there is two cameras at the start but only shows the shot from one of them during the trick...?
But yeh... any thoughts?
Okay...
Well, I like that theory except there are two problems.
1.
That is not Derren at all, and almost anybody could do that.
2. If he had been writing the numbers out as they came out, he would need to know the order. Having said this, as the balls were whirring around, he could have written on a long strip of card his prediction very quickly, then just flipped it over.
