i’m not sure exactly how to do this but tracker info is an array [x, y] so you should be able to write an expression that looked at timeline markers and then held the y value at the marker time when the hand changes direction. It would be somethin like if time< marker 1 then [tracker value x, y tracker value] then if time > marker 1 use the value of x at marker 1 for x and the tracker value of Y for y and then change for marker 2, 3, and 4 as the rectangle is drawn.

I don’t know much about expressions but i’ll bet someone here could come up with the answer.

in looking at this example I’d stabilize the shot for rotation and position, grow the comp by about a factor of 3, then lay big layers on top for the sky replacement and new sun. If you do that, than all you have to do is to remove the motion from the stabilized layer and put the inverse of that motion in the other layers. If you can get all the relative movement to go away, then put it back you won’t have any parallax problems…

you can also continue to track as points move off screen by holding down the option key(i think) and picking a new reference as points move off screen. You’ll see the attach point move right off screen as the track continues and the shot should stabilize.
