Automating coherent long-form video generation

Google Research Blog ·

Yale Song and Yiwen Song describe a unified multi-agent framework for generating long-form video narratives. They discuss failure modes in existing agentic pipelines and present the framework as a way to help creators maintain temporal consistency while retaining creative control.

  • Unified multi-agent framework for long-form video

    Song and Song introduce a unified multi-agent framework that autonomously generates temporally consistent, long-form video narratives.

  • Existing methods suffer feature drift or content collapse

    Yale Song and Yiwen Song report that existing methods suffer from feature drift, where entities and environments gradually change unintentionally, or content collapse, where narratives fail to progress meaningfully.

  • The authors aim to abstract away consistency and world-state tracking

    The authors say their goal is to empower creators to focus on creative direction and narrative design. They aim to abstract away the tedious complexities of temporal consistency and world-state tracking, without replacing human storytelling.

Contexte

Most existing agentic pipelines automate this process via chained modules but suffer from semantic drift (subtle shifts in character attire or scenery across shots) and cascading failures (e.g., an upstream asset artifact corrupting downstream video synthesis) due to independent, handcrafted prompting. Because early errors propagate and break long-horizon consistency, the process often requires exhaustive manual intervention. From a structural perspective, this reflects the classical credit assignment problem, as terminal failures are difficult to trace back to specific prompts. Furthermore,

These frameworks represent a foundational step toward unlocking coherent, long-horizon visual storytelling for creators. As we continue to refine these agentic architectures, we are exploring how to integrate human-in-the-loop workflows. of temporal consistency and world-state tracking, ensuring they remain the control of creative direction and narrative design.
