  I've got a drone shot of an area where there will be built a road in the future. The drone shot is a simple pan to the left and I want to draw where the future road will be built with line animation.
  
  I've got the shot camera tracked, but I'm having problems figuring out where and how to put the line animation when there are points that will at different times be on or outside the current camera view.
  
  Btw: I'm trying to do this in After Effects.
