The Camera Tracker node
Camera Tracker Introduction
Camera tracking is match moving, and a vital link between 2D and 3D, allowing compositors to integrate 3D renders into live-action scenes. The Camera Tracker node is used to calculate the path of a live-action camera and generate a virtual camera in 3D space. This virtual camera’s motion is intended to be identical to the motion of the actual camera that shot the scene. Using the calculated position and movement of the virtual camera provides the flexibility to add 3D elements to a live- action scene. Also, the Camera Tracker creates a point cloud in 3D space that can be used to align objects and other 3D models to the live-action scene.
For more information about how to use the Camera Tracker, see Chapter 86, "3D Camera Tracking," in the DaVinci Resolve Reference Manual, or Chapter 24 in the Fusion Reference Manual.
