Also known as 3D tracking, camera tracking is a crucial process and one of the first imperative tasks to be performed in the VFX chain, as it will ensure an accurate solve for camera movement, which in turn will have an impact on almost every other part of the video production.
This technique is about tracking the movement of a camera through a shot to recreate an identical virtual camera move in a 3D animation program. This allows for the new animated elements that are composited back into the original live-action shot to appear in a perfectly matched perspective. Tracking the motion of a live-action is most commonly done through the use of a structure from motion algorithms that use feature tracks over multiple frames to calculate the movement of the camera. The process involves a careful review and analysis of the footage data from the camera lens, angle and movement to level of distortion and solid track points, or “points for confidence” as referred to from a technical point of view.
A solid camera tracking is the backbone of the VFX work on the shot. Without it, no matter how riveting the visual effects, a feeble 3D tracking will yield an average result. For quality results, an accurate camera track is essential to being able to convincingly composite Computer Generated (CG) images into live-action footage and is the very foundation upon which everything else in the VFX chain is built.
