I went to the original image sequence and started oding manual motion tracking, watching a crater here or there. I made sure I always had at least two data points at any given time so that I could reposition and rotate for fluid motion. Then I copied that motion tracking data to some null objects, and told after effects to interpolate the data in between using bezier curves.
I know what you mean, although I did use a Bezier curve to draw Bubba's winning shot at the 10th at Augusta onto a Google Earth screenshot, so you know, really I'm right there.
