That gif isn't the clearest, I'll grant you - but I had hoped there was enough there to illustrate it. I possibly made it a bit too small, and I was really unsure what speed to choose - slow lets you see each frame clearly, but like you say you don't get the impression that you're necessarily seeing the whole story if the frames don't flow into each other quickly enough.Mark James wrote:Sorry Jon. As much as I agree that Derren is full of shit when he says all his disclaimers, I'm not seeing what you're seeing in the video. It ends up as heads sure but I can't fully make out it being heads as it enters the bowl. I'm not saying he didn't use a two headed coin I just don't think this video shows it. Camera frame rates being what they are might not fully pick up the coins movement either. I'd stick with the changing dates on the coin ahead of the video as the damning evidence.Jon Corby wrote: Head enters the bowl at the bottom, turns on its side... to another head.
Here's all 7 frames in a larger size:
Frame 1
Frame 2
Frame 3
Frame 4
Frame 5
Frame 6
Frame 7
so you can load them into whatever you like and study them individually or animate them at different speeds, whatever. Frame 1 very clearly shows the coin entering the shot showing a head. Frame 2 still has the head showing, but it's starting to turn over, Frame 3 shows the coin virtually entirely on its side, Frame 4 clearly shows another head after the turn. From then on the coin slides up the side of the bowl and comes to a rest. There's no chance that we're missing any movement of the coin, you can see its whole path if you play the frames sped up (or, indeed, just go to 4OD and watch that segment of the show - the whole coin tossing thing starts about 10 minutes in, and that's toss number 7).
It's perhaps worth noting that there is hardly any movement of the coin once it comes into shot in the bowl in any of the tosses, and I'm sure this is no accident - I'm positive the way he tosses the coin and the shape of the bowl is deliberate to avoid this. I imagine a straight-edged container (which would do the job of catching a coin just as well) would be prone to turning the coin over once it hits the bottom or the side, which obviously wouldn't do. Maybe you'd like to see more of the coin tosses slowed down to illustrate this? - I do accept that I'm not looking at this frame-by-frame toss in isolation, so I've got plenty of assurance that we're not losing anything because of the frame rate, and that the coin isn't flipping out all over the place at great speed once it his the bowl. I have realised though that this:
was possibly a stupid thing to say, as it pretty much assumes that they just had one shot at it. Maybe it's no accident that the footage almost stands up to close scrutiny, perhaps they did multiple takes and pored over the frame-by-frame breakdown and this was the one that came out on top. Hell, maybe they spent 9 hours doing thatJon Corby wrote:And as I say it was only on the 7th toss that I could catch the head turning over - suggesting that it wouldn't have been much more effort to do a run of ten spins which stood up to even frame-by-frame scrutiny.
