After Effects does not expose the camera’s Sensor Size (Film Size) to scripting.
The Problem:
Accurate camera creation and pipelines require knowledge of both Zoom and Sensor Size to correctly calculate Angle of View and Focal Length.
Without script access, it’s impossible to verify, automate, or replicate real-world camera setups in AE via scripting
Proposed solution:
Expose Sensor Size (Film Size) as a read/write property in scripting.
This would allow scripts to create cameras with the correct sensor size and accurately calculate Zoom, Angle of View, and Focal Length.
