Summary

DramaDirector is a geometry-grounded framework designed to overcome the challenges of generating short dramas from global plots and local contexts, a task where prompt-level or text-only video pipelines often struggle. It enables a planner to utilize cinematographic geometry from a gallery of real short-drama shots, indexed by depth and pose, to guide video creation. The framework decouples each shot into static visual and dynamic narrative conditions, training its planner with schema-constrained SFT and GRPO under a learned text-visual alignment reward. This process retrieves depth-pose references to inform first-frame generation and subsequent image-to-video synthesis. Complementing this, DramaBoard is introduced as a new benchmark, comprising 35 live-action dramas, 2.8K episodes, and 81K shots, featuring structured storyboards and multi-dimensional evaluation protocols. Experiments demonstrate DramaDirector's superior performance over representative multi-agent and video generation baselines in faithfulness, consistency, and controllability.

Key takeaway

For Machine Learning Engineers developing advanced video generation systems, DramaDirector offers a robust approach to producing complex, multi-shot narratives. You should consider integrating geometry-guided planning, leveraging real cinematographic data indexed by depth and pose, to enhance visual grounding and narrative consistency in your models. Furthermore, utilize the DramaBoard benchmark to rigorously evaluate your system's faithfulness, consistency, and controllability against established baselines.

Key insights

DramaDirector uses geometry-guided planning and real cinematographic references to generate visually grounded multi-shot short dramas.

Principles

• Decouple static visual and dynamic narrative conditions for video generation.
• Borrow cinematographic geometry from real-world shot galleries.
• Train planners with schema-constrained SFT and GRPO.

Method

The framework trains a planner using schema-constrained SFT and GRPO with a learned text-visual alignment reward. It retrieves depth-pose references to guide first-frame generation and image-to-video synthesis for multi-shot videos.

In practice

• Generate short dramas from global plots and local contexts.
• Evaluate video generation models using the DramaBoard benchmark.
