How does a 3D camera tracking system work?
The 3D Camera Tracker works by analysing your footage frame by frame and detecting features that it can track. A feature is a clearly distinguishable visual shape in your clip that represents a fixed location in space. Moving objects like people and cars are not features and tend to interfere with the 3D camera Tracker.
