Re: Here's a challenge: Stabilising a rotating shot...

What version of After Effects are you using? CS 5.5's Warp Stabilizer should be able to help with this shot.

Or if you have access to The Foundry's Camera Tracker, there's a workflow you can use to stabilize footage with that.

Otherwise I think the solution may be painful. For example, you can move the point tracker to focus on a new feature without moving its attach point. You could select new track features as the old ones leave the frame. However, this is complicated by parallax, things at different distances from the camera will move at different rates. Still, there may be a potential solution there.
