The cool thing about my technique is that, as a director, you can really dial in the look you want for the camera motion... and it's got some "life" to it... the cam op's heartbeat show up as does the breathing. These don't exist in digitally created motion FX. If the cam op has to run, the speed of this motion increases as they catch and control their breath... plug ins don't show that and it "feels" artificial.
and if you have a motion tracker, it's super fast to apply - compared to hand keying the motion frame by frame.
