Co-Director: Hierarchical Multi-Agent Framework for Video Storytelling

A new study introduces Co-Director, a structured approach to help multiple agents work together on video storytelling by treating it as an overall optimization problem. It uses a multi-armed bandit strategy to explore creative possibilities, while also implementing a local self-refinement loop that helps maintain consistency in character identity throughout the story. This technique strikes a good balance between trying out new narrative styles and using effective methods. The researchers also present GenAD-Bench, a dataset with 400 scenarios that feature fictional products for personalized ads. Results show that Co-Director improves semantic coherence compared to current agent-based systems, which often struggle with semantic drift. You can find the paper on arXiv under the ID 2604.24842.
