Hey BlenderNation!
This video shows how to 3d track your live action footage in Blender and then recreate the lighting in Blender so that you can add cgi to over your footage in compositing! Part two in After Effects coming soon! Let us know what you would like to see next!
Our Blender Add-ons:
I am a cinematographer based in Los Angeles. I have been using Blender for many years now in creating basic 3d VFX for films. I am one of the creator's of an asset based add-on for blender called LightArchitect (www.lightarchitectaddon.com) that allows pre-visualization of Industry Level lighting and camerawork inside of Blender.

Instead of visually instpecting for tracking slippage, use the graphs to find the trackers with the most errors. In the dopesheet you can sort trackers by reprojection error, and delete the ones with high values. Also in the speed graph at the bottom, if you select the points in the graph that are clearly deviating from the average, the tracker will be selected, so you can delete it as well.
Note that is also important to find the optical center of the lens as well as the distortion, so set the optimization to lens, k1, k2 and optical center.
