I count 29 shots of the robot are needed. Many of those shots, however, are the same angle -- just later on in the scene. So there are about 20 "camera setups" with the robot.
Right this minute that seems doable. The robot is getting better and better all the time. With Blender I've figured out how to incorporate depth of field using compositing nodes (by estimating the fstop we were at out in the field -- usually it was up there at around f8).
I really wish I didn't know anything about compositing nodes. My brain hurts.
Since we've given up on our version of the teaser, I decided to take some time to do some color-correction and letterboxing. So think of this as the "director's cut" of the teaser.
