It's *kinda* like stop-motion.
The workflow now is you shoot your live footage - keeping in mind where you want your CG character to be placed in the shot. Then, in the computer, you use specialized software to 'track' the motion of the camera. This allows you to simulate the camera moves in 3D space so that you can then animate a digital character TO THAT CAMERA. Then the individual character animation is rendered out separately because it then goes to another piece of specialized software for compositing - or making the animated character 'live' in the original shot.
The end of this particular shot has the cg character transform into a motorcycle that was really there on set. So, the animator and the compositor must be sure to make the character's end position resemble the motorcycle's position as closely as possible in the software. The closer they can make it appear, the easier it is to fade out parts of the digital character in order to reveal the real bike that has been there the entire time.
Now, there is a lot more to it than that - many other important pieces to the creation of the character and all - but that is the general gist of how the shot is generated.
