Sorry for reactivating this post but I am trying to achieve the same thing. I set up my null objects with tracking data and now I am stuck. I am not sure how to stabilize the footage using the null objects that contain the tracking data. I know I have to parent some stuff but I need to only stabilize the y direction since my pan is in the x direction. However my null objects have both x and y tracking data so a simple parent of my footage to the first null object causes the entire footage to go off screen. Any ideas on what I should do? The tracking for each of my null objects is done like in the Set Extensions tutorial except I have 12 null objects instead of 2. They are parented up like in the tutorial and that works perfectly so that anything I parent to the first null object will follow it through the pan. I dont need the x data and only want to apply the y data and the rotation data to my footage to stabilize it but I am unsure how to do this.
