First attempt at Motion tracking

This is my first attempt at motion tracking using the software PFTRACK firstly i took the footage and i used the Track and solve option and it automatically tracked the footage and set tracking point data. Then when this was finished it also set a ground plane and initially the ground plane was to high so moved it down and added some some 3d objects into the tracking data and it placed them near the tracking points.

I then exported this from PFTRACK as an .ma file and opened it in maya where i placed some spheres in the terms of perspective.

Heres the Maya
