Hello all !

Im not sure i should be posting this here or in the basics .. anyway here it goes.

i have this shot of someone walking in a green screen , but the camera is following the person walking .

i want to eliminate the camera moving and have the person walking.

for that i tracked the background , a perfect track using 3D tracker Camera effect and i made a track null and a 3D tracker camera.

so now i want to have the source layer position linked to the tracker in a way that the camera movement is eliminated and we see the person changing position on screen instead of walking in the same position.

i tried parent the source layer with the null layer , with the 3D tracker camera layer , i tried linking with expression ... nothing worked

the result is the frame moves in the oposite direction that is needed to achieve what i want.

AE's 2D tracker set to track for stabilization should do the trick. Just track the person and all should be fine.
