Tracking provides Live with information about the way objects in the shot
appear to move. Just as objects move in your field of view when you walk by
them, the way objects move in the camera view gives Live information on
how the camera moved during filming.
Youll track points for various spots, such as a mark on the fence. To track a
point, you mark each spot in the image and have Live run a tracker that
automatically follows the points movement from frame to frame. The result
is called a track point.
Later, in the solve task, Live will animate a Maya camera based on the track
point movement.
