Il y a bien déjà ce début d'explication sur le site de Sony:

I believe it's done through cutting out the different planes of depth and then doing camera projections. (Ack, not the greatest explanation.)
So you split up the image into two or more planes.
One is the surfer (sorry, probably not the right term).
The other is the ground. There will be a hole there so bits of it will be cloned/painted in.
Those two planes are stuck into a 3-D environment.
There are probably 2 camera angles. (More angles is better but I didn't see that many cameras.)
The camera move is done in a 3-D space (kind of like 3-D compositing in Vegas). Blending between the 2 camera angles is probably some combination of optical flow + paint work. The in-between frames are made up via optical flow (similar idea to face morphing stuff if you've ever seen programs which morph one face into another).
Certain semesters of fxphd.com go through this. I don't know of any free resources off the top of my head. But it's likely a combination of camera projection and optical flow + paint work. There is some camera projection information on Google.
2- If you look in the background of the shot I think you will see that it doesn't look right.
Et cet autre qui pense connaitre l'auteur:

The kite and surfer had to be keyed
Boris does a very cool alpha key separation after looking at that clip I replicated the echo in Vegas [past 8 levels up an move each one in position} but only after I did an alpha key in boris as a plug direct
But the 3d pans fast to slow are perfect, need to suss that out. The water drops are easy enough [Mr Murcury ]Boris
The editor of that clip although shot in Cape town might be a Durban guy Zazman . D Zastron {we worked on some projects together a few years ago} has done similar stuff I will email him and see if he will post a reply here if anyone is interested.
