ParaScale: Scale-Calibrated Camera-Motion Transfer via a Gauge-Invariant Parallax Number
ParaScale introduces a geometric solution to camera motion transfer in video generation by identifying and preserving the Parallax Number (Pi), a scale-invariant metric that quantifies perceived camera movement independent of scene depth. The method enables creators to transfer cinematic camera movements between videos at vastly different scales without requiring retraining, improving transfer fidelity by over 3x compared to uncalibrated approaches.
