CGMatter covers all the fundamentals of motion tracking using Blender.
Blender is a fantastic piece of software. Not only is it free and open-source, but it’s also a jack of all trades with some pretty amazing features in some places. For example, Blender is pretty much all you need to create virtually any type of visual effects. Check out this tutorial from CGMatter that dives into using Blender for motion tracking, a staple workflow for visual effects.
The tutorial is over an hour long and covers everything you wanted to know about motion tracking in Blender. “Specifically, we go over image sequence conversion and the motion models (location, rotation, scale, affine, perspective) used for tracking.” The tutorial represents the first part of a three-part series, with the other two pieces on their way.
