Autodesk^® MatchMover^TM is a camera tracking application that automatically captures 3D camera path and camera parameters from 2D video and film image sequences. After capturing a 3D camera path with MatchMover, you can export the camera data to a number of file formats supported by 3D animation or compositing programs. This allows you to work with the camera data in your favorite animation or compositing application to accurately place 3D objects into a video or film sequence. Providing a straightforward and cost-effective way to mix 2D live-action footage with 3D animation and special effects, MatchMover allows you to take advantage of the 2D world of film and the 3D world of animation.

MatchMover extracts all camera parameters from information contained in a film sequence. From a set of 2D points automatically tracked through an image sequence, MatchMover computes the following:

• The camera path and all the camera internal parameters such as zoom and distortion.
• The coordinates of the 3D points that project onto the 2D point tracks.
• The motion of independent moving objects.

A preview sequence with additional computer-generated objects in the scene can be generated to check the quality of the tracking result. If necessary, post filtering can be used to smooth the computed camera path. The camera data is then ready to export to an animation or compositing program.

With MatchMover, no geometric data from the set or from the camera is required, but they can be used for faster computation and stronger constraints. Integrated high-end 2D tracking modes enable very precise camera reconstruction. MatchMover works with any type of camera equipment, any image resolution, and can process any camera path in the most commonly used image formats.
