I'm trying to stick a logo to a building using the motion tracking feature. It works OK, but the target object (logo or red rectangle on the video) is a bit shaky. I tracked both position and size. How can I make it more stable? Also, how can I make the perspective of my red rectangle change overtime, to follow the changing vanishing points?

Thanks to you all. I will look into Mocha. I always find it surprising and above all frustrating when a software like AE can't do this kind of routine function and you need to purchase a 3rd party plug-in. I mean, why doesn't Adobe simply purchase Mocha and includes it in AE?

Mocha AE is included. There can be a huge difference in tracking accuracy between a feature (not point) tracker like the default AE track motion and a planar tracker.

I agree with Rick. This woulkd be a typical case for a palanar track. That aside, the biggest problem in your shot likely is that you may be limiting the tracked area too much. It would be more stable if you used a larger section and perhaps even worked out something using multiple tracks on the few distinct features that are there.

I would use Mocha AE, and corner pin track the side of the building.

Here's an introductory course on Mocha. I think you'll have better luck than Camera Tracking. Drill down to the Using Data section after you figure out how to track perspective.

You may want to try the 3D Camera Tracker effect.
