What you describe below is how I did my shot this morning. Motion tracked, =
then hand-finessed by setting occasional anchor point keys. Turned out awes=
ome. Quite pleased with myself. ; )  Exported patch layer as AVI+Alpha and =
overlayed the clip in Pr. I set the patch layer to be a 3D layer and turned=
 on motion blurring. The motion blurring of my patch.png file matches the o=
riginal clips shutter angle set at 180=B0 .

Yeah, sometimes hand tracking is all you can do. I've been using Command-Le=
ft and Command Right and just the arrow keys themselves lately to do the ma=
nual tracking without having to lift my fingers off the keyboard. Being abl=
e to quickly flip back and forth between frames means I can pretty quickly =
see whether a point is locked without having to do averaging. I also have a=
 habit of flipping forward a few frames to see where the motion of an objec=
t shifts. Let's me get away with only setting track points every few frames=
 sometimes.
