In this Tutorial you learn how to use the mamoworld After Effects tool Tracker2Mask to assist you in your rotoscoping tasks.
Tracker2Mask computes the movement of maskshapes based on the movement of trackpoints. It is easy and flexible to use. In particular you don't need one trackpoint for each maskpoint. In the tutorial I show how to rotoscope the shape of a moving car in After Effects based on only four trackpoints, for simpler shapes often one trackpoint is sufficient.
