1.3 The Importance of Film Back

Why is it important to make sure PFTrack knows the correct sensor size? When solving a scene, PFTrack has to determine a plethora of information about the camera and location a clip was shot. The more information you can give PFTrack about the camera and scene you are trying to solve, the less PFTrack has to figure out itself and the quicker and easier it is to get a good result.

2.3 Using Multiple Views to Solve Nodal Pans

There is one special kind of camera motion, that requires additional views to extract any kind of 3D: Nodal pans. This tutorial explains what nodal pans are and how they are different from other camera movements. After that we will use the same technique shown in the live session to add additional camera views of the same scene in order to obtain a real 3D result.

2.1 Solving Multiple Cameras Into a Single Scene

When tracking multiple shots from the same location, it is often important that every shot shares the same coordinate system. This way we can ensure that key locations are identical independent of which camera solve is worked on. A straightforward way to ensure a shared coordinate system for multiple cameras is to track and solve them into the same scene in PFTrack.
