Dreamfire Films created this short Scifi film and expand on how they set up the tracking.

A short VFX film where Blender was used to add some robots. The large mech model is available for free and was first created by a modeler named Hulis which I then re-textured so it would work with Cycles and gave it its walking and shooting animation. I also made a step-by-step VFX motion tracking tutorial so people could easily put the model into their own films. I hope you can find this useful.
