The film One and Only features multiple large-scale crowd scenes depicting packed audiences in full-throated celebration. CHINGMU optical motion capture cameras recorded the real human motions involved — arm waving, glow stick movement, and body movement — converting this data for processing by a proprietary software algorithm that drove pre-built 3D character models representing individual audience members. Crowd simulation techniques were then applied to populate the venue with these individually differentiated audience characters, each performing their unique celebration motion — ultimately producing high-definition, fluid wide-shot imagery of a packed crowd waving glow sticks in unison.

By capturing the full-body performance of a single motion capture performer with high precision, the team successfully recreated the full range of crowd celebration detail. The system's high accuracy, low latency, and robust tracking characteristics further elevated the realism and precision of the final film imagery.

The project was developed collaboratively by Shanghai Jinglang Cultural Media and faculty and students of the Digital Entertainment Center at Shanghai Film Academy, integrating digital virtual human technology with motion capture — with CHINGMU providing motion capture system services and technical support. This deep integration of industry and education proved an effective model for developing the specialized technical talent most in demand by the market today, aligning Shanghai Film Academy's curriculum closely with industry production requirements.

As the film industry continues to evolve, the integration of character modeling and motion capture technology has become an indispensable element of modern production.
