The crew adopted CHINGMU's optical motion capture system and virtual camera CMVCS for Previz of complex scenes such as maritime rescue. CHINGMU's Previz technology allows the creative team to verify ideas in virtual space, optimize camera angles, character movements and scene layouts without relying on real environments. Real-time synchronization of motion and camera data achieves "what you see is what you get", reducing on-set trial-and-error costs and shortening shooting cycles.
