Cool. JBean, I think you pretty much shed all the lights on how these were done. Again, very impressive and these guys really have creative ideas.
Maybe they should include one trick that I used to do since its a lot easier is have one guy stand still in a background like on the park. Then spins around, then leave. Then have the other guy stand on the same spot where the first guy was, and spins around too. maybe the first guy should spin clockwise, and the 2nd guy should spin counter clockwise. When edited them, overlap about 1 second of the two guy standing on the same background spinning. And when play it back. It should makes it looks like the first guy just transforms into the 2nd guy. They could make it more creative than that like maybe as they spin, the guy transform to different clothes, and transform backward and forth with different clothes on. Or something like that.
Another one, have one guy standing on the background, put one hand out, say his left hand with his palm opens, and still standing still, snap a finger with his right hand. Have someone hold something say like a rake and approach him and place it on his left palm. Then edited the part where the other guy place the rake on his hand. And when play it back, it should looks like the guy just snap a finger and the rake magically appear on his other hand...
Mine ideas isn\'t as creative as their in comparison, and not to mention their ideas took a lot of hard work and a lot of time too. Hats off to them.
