And thinking about it, you might not even need a 3D tracker, just the regular 2D AE tracker. If you've got an object in the far distance that you can track then just use After Effects.
The secret here is to find an object in the furthest plane of your image. Otherwise the parallax motion will make it look wrong.
Or you can use a 3D tracker and let it build a virtual camera. The 2D option's quicker!
