Two point tracking in blender

We already learned how to extract location information for 2D compositing using the tracker, in this lesson i will show you how to use 2 track points to grab rotational information from your videos and apply it to a background image.

Also we show on the website how to use 2d stabilisation to steal tracked data and apply it to fixed images so you can turn a still image into a handheld video effect
