ChronoLock proactively protects shared videos from unauthorized text-to-video personalization. It applies bounded perturbations to temporal denoising trajectories to disrupt motion learning within video chunks and continuity across chunk boundaries. Transformation-sampled optimization improves resilience to common preprocessing, and evaluation on UCF Sports and HMDB51 measures the reduction in motion imitation.
