I`ve shot some timelapse footage that needs to be stabilised.
On this particular clip, because I knocked the camera to the left during the sequence, (Only a few degrees), I want to have the anchor point off centre.

I want to have the 2 track points on the left, (One above the other), and the anchor point on the far right, rather than in the middle. As I thought this might be the best way to line up the frames.

In the composition panel-
I use the Pan behind tool, and move the anchor point to the right on the frame to the desired place.
Back to the move tool.

In the layer panel-
I go into Animation, then stabilise Motion.
I move the 2 track points to the left to the desired places.
I go to view, anchor point path, and make sure the anchor there is in the desired place too.
I press start. Once finished, press apply.

Once it goes back to the layer panel I see that anchor point has moved.

And for some reason it moves to the same position as track point 1.
I cannot seem to disable the link between the anchor point and track point 1?

I have seen where the problem starts, when I move the track point, it`s moving the anchor point too.
Even when I add a keyframe for the position and anchor points it does not seem to lock the anchor point to the desired place either.

I know it may be easier to reshoot the timelapse again, but I`m sure there is a way to do this.

Thank you

You could let the tracker do its thing and stabilize the footage (see Track or stabilize motion (CS5) [link] or Stabilize motion (CS5.5) [link]), then precomp the stabilized footage and then adjust the anchor point on the precomp.

Stabilize as per normal and then create a Null to which you will Parent the Stabilized layer. Then keyframe the Null's position to suit your needs.
