I watched it again with a friend who works on stages all the time, and whose father is a cameraman.
He said that the boxes in the background look just like ordinary "power distros". This is just like an industrial version of a power strip
(multiple outlet extension).
He didn't think they look suspicious, I know somepeople thought they might be part of the trick, or even stuff like the lasers that would 'paint'
the balls, or for projecting images onto the balls...
He thought that the picture shaking was very dubious. He said that even with a camera slung under the arm, or hand-held, there should never be that
much, unless the guy has Parkinsons, or is deliberately doing it for effect (like in drama shows where they want it to look more frantic). Especially
when it's a professional camera guy.
Something I've seen other people point out, is that at the start of the show, he did a cut away to the back of the room, which showed a man with a
camera.
Perhaps, that was inserted footage, to give a reason for the shakiness. Perhaps in reality it was a regular TV camera on wheels that can be rolled
around, and kept very very still when needed.
The shakiness could be added on very late in the chain, it's a very easy effect to do in real time, and might help cover up when they do the actual
switch.
A way to do the switch that can be done in realtime, and not even much technology, would be a subtractive filter. You can subtract one image from
another in real time, and if the images match you will get a pure black on that view. You can use that to make sure you are aligned as best as
possible with the dummy overlay and the main footage. Then when the switch is done, you can just use a realtime fade, added with the shakiness,
no-one would notice.
This just assumes very basic equipment. They could be using even more complex real time effects like motion tracking to make the alignment, and a
'morph' type effect rather than a fade, to make it even smoother.
I know this doesn't add any new smoking guns to that the camera trick theory, but I think it fleshes out some details I've not seen anyone cover.
