Hi I've spent some time researching this question without success. I know how to stabilized camera movement and link a layer to the camera motion in a composition. How would I link a layer to a moving item within the composition. For example how would I link a character to a moving truck that crosses the screen?
It should be as simple as motion tracking a point (or two points for scale and rotation) and applying the tracking data to the layer that you want to move with that point (or, for additional control, to a null that you parent the layer to.)
