AVCam vs Apple Photo App for stabilized video recording

Why do Apple’s builtin Photo app produce videos with better image stabilization than what I can get when I enable cinematicextended as preferred stabilization using the AVCapture API?

Ref: https://developer.apple.com/documentation/avfoundation/avcapturevideostabilizationmode/cinematicextended

I have based my work on https://developer.apple.com/documentation/avfoundation/capture_setup/avcam_building_a_camera_app

Do the Apple Photo app use another API or some Apple properitary algoritms to achieve a better result than what’s available using the AvFoundation API?
