This presentation builds on the MovieLabs 2030 Vision for the future of media creation by providing additional information on software-defined workflows. The film and TV production process is a combination of manual and automated processes. The goal of implementing software-defined workflows is to support the human creative tasks by connecting them to the greatest extent possible through software-mediated collaboration and automation. This can revolutionize the production process, making it nimble and adaptive. Building on these concepts, we propose a framework that allows the software to understand and communicate information about workflows. We describe the essential formalisms and specific mechanisms that can enable flexible workflows with increased automation and interoperability. This enables the development of interoperable tools that will support automation in a myriad of areas such as collaboration, compute and rendering orchestration, asset movement, cost calculation, personnel scheduling, and project dashboards. The presentation introduces an approach that can be immediately applied to workflow and tool development.
