The gist

ViMax is a multi-agent video generation framework from HKUDS designed to overcome the limitations of current AI video tools, such as short clip lengths and inconsistency. It automates the entire production pipeline, from scriptwriting and storyboarding to final video rendering. The system takes a narrative concept—an idea, script, or novel—and transforms it into a complete, multi-shot video story with coherent characters and scenes.

What it does

Generates complete video stories from raw ideas using a multi-agent workflow.
Adapts novels into episodic video content by compressing narratives and tracking characters.
Creates videos directly from user-provided screenplays, giving control over the story.
Integrates a user's photo to create cameo appearances in generated videos.
Simulates multi-camera filming to maintain consistent character positioning and backgrounds.
Performs automated consistency checks on generated images using visual language models.

How it works

ViMax is a self-hosted Python framework installed by cloning its GitHub repository. Users configure API keys for external services (chat, image, and video models) in a YAML file. By running Python scripts, users can provide an idea, script, or novel as input. The framework's multi-agent system then orchestrates the entire production process, generating storyboards, selecting reference images, and assembling the final video clips, which are saved to a local directory.

Best for

ViMax is best for developers and technical creators who need to programmatically generate consistent, multi-shot video content from narrative text and want to automate the complex production pipeline.

Watch out for

This is a technical framework, not a simple web app. It requires users to clone a repository, manage Python dependencies, and provide their own API keys for multiple third-party services, which may incur costs.
