simplifies the process of matchmoving. Matchmoving is a process
where you match the camera or object movement in a live-action shot with the
camera in Maya. This subsequently lets you place your 3D objects into live-action
footage.
Matchmoving is an iterative process where the camera movement for the Maya
camera is calculated using processes of tracking and solving.
Objects are tracked in the live action scene and a solver then calculates the
camera position for a given image. This chapter includes the following lessons:
Lesson 1 Track and solve:

About Live
Imagine that you must replace the contents of a live-action shot of a fence with
a fence modeled in Maya. In the live-action shot, the camera sweeps around
the fence. You can use Live to animate a Maya camera that sweeps around your
modeled fence in the same way. When you render the Maya fence from this
camera, it will have the same camera perspective as the live-action fence. You
can therefore composite them together precisely.
