Google Research introduced a unified multi-agent framework that autonomously generates temporally consistent, long-form video narratives, addressing identity drift and cascading failures in current linear AI pipelines.

The framework, built as an orchestration layer on top of Gemini and Veo, includes components such as Co-Director, CANVAS, A²RD, and VQQA, and uses hierarchical parameterization with a multi-armed bandit algorithm to optimize creative directions.

Evaluations showed substantial gains in multi-shot narrative consistency and character persistence, enabling minutes-long videos while mitigating visual drift and pipeline error propagation.
