Movie-as-Code (MaC) is a play on Infrastructure-as-Code (IaC) which in the computer science domain means:
"Infrastructure as Code (IaC) is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools."
So in case of Movie-as-Code (MaC):
"Movie as Code (MaC) is the process of managing and provisioning movies through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools."
