What is ViMax?

ViMax, developed by the Data Science Lab at the University of Hong Kong, is an end-to-end multi-agent video generation framework that supports the automatic transformation of ideas, scripts, or novels into complete videos. The framework integrates the functions of a director, screenwriter, producer, and video generator, supporting modes such as Idea2Video, Novel2Video, Script2Video, and AutoCameo. It can generate minute-long videos while maintaining consistency between characters and scenes. Through technologies such as intelligent storyboarding, multi-camera simulation, and automated consistency detection, ViMax achieves a highly efficient and automated workflow from idea to finished product, greatly simplifying video creation, lowering the technical barrier, and providing creators with powerful tools.

ViMax's main functions

  • Idea2VideoTransform simple creative concepts into complete video stories; suitable for initial ideas without a detailed script.
  • Novel2VideoIt automatically adapts long novels into episode-based video content, making it suitable for adapting literary works into film and television.
  • Script2VideoIt generates videos based on detailed scripts, making it suitable for creators who already have mature scripts.
  • AutoCameoAfter users upload photos, videos featuring their own image are generated, enabling personalized interactive experiences.

ViMax's technical principles

ViMax uses a multi-agent collaborative architecture to break down the video generation task into multiple modules, which are then completed by different agents:
  • Input parsingExtract key information from the idea or script, such as characters, setting, and style.
  • Script understanding and storyboard designBased on the extracted information, a detailed storyboard is generated, and shooting angles and narrative rhythm are planned.
  • Visual asset planningIt intelligently selects reference images and designs suitable scene layouts and styles for each shot.
  • Consistency checkUse MLLM/VLM models to detect the consistency of generated images, ensuring that people and scenes are consistent in the video.
  • Parallel generation and synthesisIt efficiently generates shots using parallel processing technology and stitches them together to form a complete video.

ViMax application scenarios

  • Short video productionCreators can quickly turn their ideas into short videos for use on social media platforms such as TikTok and Bilibili.
  • Educational VideosTransforming complex teaching content into vivid videos helps students better understand and remember it.
  • Interactive videoThe AutoCameo feature allows users to incorporate their own image into videos, increasing interactivity and fun.
  • Novel VisualizationAdapting novels into video content provides a new form of dissemination for literary works.
  • Personal story videoUsers can turn their stories or creative ideas into videos for personal commemoration or sharing.
