AI Person Detection: TensorFlow.js + COCO-SSD with 60 high-precision tracking points
Hermite Spline Interpolation: Velocity-continuous curves (Hollywood animation standard)
Spring-Damper Physics: Real physics simulation for natural camera motion
Motion Prediction: 0.5s look-ahead anticipates subject movement
60Hz Trajectory: 1800 calculated positions per 30 seconds
Adaptive Smoothing: Stronger smoothing on fast motion, lighter on slow
Ease-In/Ease-Out: Professional acceleration curves on every movement
Critical Damping: Smooth settling without oscillation
Gesture-Aware Padding: Keeps hands/props in frame
Up to 30s: Professional reframing on first 30 seconds

Cinema-grade physics: spring-damper system + motion prediction + 60Hz trajectory = Hollywood-level smoothness.
