VACE is a set of software tools and frameworks for reference-guided video generation, diffusion-based editing, and video-to-video translation. It provides utilities to produce new video content and modify existing sequences by using reference materials to guide visual style, subject matter, and composition.
The framework enables video-to-video translation and synthesis, allowing for the update of visual styles and depth. It also functions as a video editor for modifying properties and content through reference-guided transformations.
The system covers localized video editing and inpainting, which allows for the replacement or modification of specific objects and areas using masks or bounding boxes. It also includes capabilities for general video content transformation and visual structure generation.
