Tracker2Mask for tracker-assisted rotoscoping
Tracker2Mask is a new script by Mathias Möhl. It 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 he shows how to rotoscope the shape of a moving car based on only four trackpoints, for simpler shapes often one trackpoint is sufficient.

Here is a second tutorial that explains some new features that allow the local manipulation of parts of a mask: http://www.vimeo.com/2535683
