CineAGI: Character-Consistent Movie Creation through LLM-Orchestrated Multi-Modal Generation and Cross-Scene Integration
Abstract
Automated movie creation requires coordinating multiple characters, modalities, and narrative elements across extended sequences -- a challenge that existing end-to-end approaches struggle to address effectively. We present \textbf{CineAGI}, a hierarchical movie generation framework that decomposes this complex task through specialized multi-agent orchestration. Our framework employs three key innovations: (1) a multi-agent narrative synthesis module where specialized LLM agents collaboratively generate comprehensive cinematic blueprints with character profiles, scene descriptions, and cross-modal specifications; (2) a decoupled character-centric pipeline that maintains identity consistency through instance-level tracking and integration while enabling flexible multi-character composition; and (3) a hierarchical audio-visual synchronization mechanism ensuring frame-level alignment of dialogue, expressions, and music. Extensive experiments demonstrate that CineAGI achieves 40\% improvement in overall consistency, 4.4\% gain in subject consistency, 5.4\% enhancement in aesthetic quality, and 28.7\% higher character consistency compared to baselines. Our work establishes a principled foundation for automated multi-scene video generation that preserves narrative coherence and character authenticity.

Research summary
CineAGI represents a significant advancement in automated movie creation through its innovative multi-agent orchestration framework. The comprehensive methodology and substantial experimental validation establish it as a leading approach in the field, with the potential to reshape how narratives are crafted in digital media.
Methodology
The methodology presented in CineAGI is robust and innovative, leveraging a hierarchical multi-agent orchestration approach to tackle the complex task of automated movie creation. The use of specialized LLM agents for narrative synthesis, character generation, and cinematographic synthesis is a significant advancement over traditional end-to-end models. The framework's ability to maintain character consistency and narrative coherence across scenes through decoupled processing and explicit synchronization mechanisms is particularly noteworthy. The detailed breakdown of each module and the integration of various generative models demonstrate a comprehensive understanding of the challenges in automated filmmaking.
Results & evaluation
The experimental evaluation is thorough, utilizing a diverse benchmark of 100 story prompts across multiple genres to assess the framework's performance. The use of both quantitative metrics and qualitative human evaluations provides a well-rounded perspective on the system's effectiveness. The reported improvements in consistency and aesthetic quality are substantial, indicating that the proposed methods yield significant enhancements over existing baselines. However, the paper could benefit from more detailed comparisons with a wider range of contemporary methods to further contextualize its contributions.
Reproducibility
The paper provides a detailed description of the experimental setup, including generation settings, evaluation metrics, and baseline comparisons. However, the lack of publicly available code or demo URLs limits reproducibility. Future work should consider releasing the implementation to facilitate further research and validation by the community.
Limitations
One limitation of the study is the reliance on specific generative models, which may not generalize across all contexts or genres of filmmaking. Additionally, while the framework shows improvements in character consistency and narrative coherence, the complexity of the system may introduce challenges in real-time applications or scalability. The computational cost of approximately 11.3 minutes per scene on a single GPU could also be a barrier for broader adoption.
Broader impact
The implications of CineAGI extend beyond academic research into practical applications in the film and entertainment industry. By automating aspects of movie creation, this framework could democratize content production, enabling creators with limited resources to produce high-quality narratives. Furthermore, the integration of AI in creative processes raises questions about authorship and the role of human creativity in storytelling. CineAGI represents a significant advancement in automated movie creation through its innovative multi-agent orchestration framework. The comprehensive methodology and substantial experimental validation establish it as a leading approach in the field, with the potential to reshape how narratives are crafted in digital media.
