Virtual production technology is becoming more mature and is widely used in the production of video content such as movies, drama series, and advertisements. In the two solutions of virtual production (Live LED Wall Cinematography and Live Compositing), the virtual camera and the real camera are required to be identical, that is, after the synchronization of the intrinsic hardware parameters of the real camera and the virtual camera, the exposure parameters of the real camera are changed during shooting, the corresponding parameters of the virtual camera must also be changed to ensure the consistency of the picture. At present, most virtual production studios use camera control systems that are transformed from broadcast camera consoles usually require cumbersome accessories and high prices. During the actual production process, a camera control system using the Arduino development board is found, which inherits the characteristics of easy-to-operate and strong adaptability of the Arduino development board. The serial digital interface camera control protocol provided by Blackmagic Design (BMD SDI CCP), allows the virtual camera (CineCamera) in the virtual production engine Unreal Engine 5 (UE5) and the real camera to communicate in real-time through the use of serial communication. This paper uses literature analysis to explore the necessity and functional requirements of virtual production camera control systems and the feasibility of the virtual production camera system proposed in this study through analysis of academic journals, industry white papers, professional practitioners, and organization presentations. Descript the hardware requirement and design code for the camera control system, verify the feasibility of the system through empirical research, and provide a camera control system that can be customized for individuals or teams who want to make video content through virtual production.
