Some further practice with 3D Tracking

Breakdown of some basics skills learnt in Autodesk Maya and Matchmover, building on what I've learnt from Esacpe Studio Tutorials and my own headscratching. Tracking live action background shot and placing 3D animated Character in Scene. This is an early attempt to put some practice into tracking some poorly lit / non marked footage before doing more complicated stuff requiring multiple passes and after effects. The video was shot on a Nikon D90 - 1280x720px - to take into account the Camera Sensor being cropped when shooting 16:9 - the Film Back settings in Matchmover worked out as - 23.6 x 13.2mm approx...  the Focal Length was 18mm.
