Depending on your system, this may take a while.After Effects opens the Effect Controls panel and displays its progress as it analyzes the footage
in the background. When the analysis is complete, many tracking points appear in the
Composition panel. The size of a tracked point indicates its proximity to the virtual camera:
Larger points are closer, and smaller points are further away.
Tip
The default analysis is usually sufficient, but you can perform a more detailed
analysis to better solve the camera position. The Detailed Analysis option is in the
Advanced area of the Effect Controls panel.3. When the analysis is complete, choose File > Save to save your work so far.
