Matchmoving is the computation of the global 3D geometry of a scene including camera path, internal parameters, and moving object. By exporting the real 3D camera path and parameters to animation software, the position and motion of virtual cameras can be accurately established. With the motion of the virtual cameras, new, matched image sequences can be created whose virtual objects are seamlessly composited into live action footage.

Matchmoving lets you accurately place 3D objects into a film, video or image sequence. For virtual objects to appear as part of the scene, the objects have to be rendered by a virtual camera whose motion exactly matches the motion of the actual camera that shot the film. Using Autodesk MatchMover you can generate the exact camera parameters that match the motion of the actual camera used in the sequence.
