DramaDirector: Geometry-Guided Short Drama Generation

DramaDirector is a geometry-guided framework designed for generating short dramas by transforming global plots and local contexts into visually grounded multi-shot videos. It utilizes schema-constrained supervised fine-tuning (SFT) and geometry-reinforced planning optimization (GRPO) to decouple static visual and dynamic narrative conditions, enhancing first-frame generation and image-to-video synthesis through depth-pose references. The framework is evaluated against a newly introduced benchmark, DramaBoard, consisting of 35 live-action dramas and 81K shots, demonstrating improved performance in faithfulness, consistency, and controllability over existing multi-agent and video generation baselines, making it a significant advancement for practitioners in video generation and narrative-driven AI applications.
