This paper examines the current state of long-form video generation. It highlights the challenges of long-form video generation (planning, storytelling, maintaining spatial and temporal consistency, etc.) by highlighting the limitations of even existing state-of-the-art systems for generating 1-minute videos. It covers the overall field of long-form video generation, including fundamental techniques such as generative adversarial networks (GANs) and diffusion models, video generation strategies, large-scale training datasets, quality metrics for long-form video evaluation, and future research areas. It suggests the potential for improved scalability and greater control by integrating a divide-and-conquer approach with generative AI. Ultimately, it aims to provide a comprehensive foundation for the advancement and research of long-form video generation.
