This motion control shot was setup on-location in the Salt Lake City airport. The foreground talent was shot against blue and speed-ramped from 24 to 80fps (with an assosiated ramp in the dolly, pan, tilt and focus moves and, of course, a compensating shutter move for the exposure change). The background action was filmed seperatly at 24fps but slowly defocused durring the shot. An interesting effect.
