Anybody who's done any 3D stuff should be amazed at how the robot moves.
The way it was matched to the camera movement is incredibly realistic!
The video editing was excellent.
the running scenes look a little too real,, all generated ?
Yes, all cgi. The term escapes me at the moment, but they probably used a digitized, live-action reference film. The actor wears a black skin-tight body suit with reflective balls located at certain points on the human frame. Those balls, as the figure moves, are scanned into a computer which can duplicate those movements so the cgi animation will appear more fluid and human-like.
The man responsible for this ad is Neill Blomkamp / The Embassy.
I've not spoken to him in a couple years so I'm not sure what he's up to. But I'm sure it's something groundbreaking in the area of 3D animation and/or film direction. Real nice guy, and incredibly talented. He was based here in Vancouver last I heard.
Do a search under his name or The Embassy FX to see more of his work.
An old high school buddy of mine made a fun short with him once. Kind of a take off on the Kung Fu fighting/Matrix movies. All very tongue in cheek and very fun.
