Creating and editing videos has always required juggling multiple tools like having one tool for generating videos, another for editing, and yet another for refining details, which makes the process long and exhausting. VACE is a unified tool developed by Alibaba’s Tongyi Lab designed to eliminates that hassle by consolidating the entire feature inside a single tool. This all-in-one AI model streamlines video generation and editing, bringing everything under a single framework. Vace integrate all requirements of various video creation and editing tasks such as editing, reference, and masking, into a unified interface known as the Video Condition Unit (VCU).

What Makes VACE Stand Out

Unlike traditional AI models that focus on a single task, VACE handles everything:

1. Reference-to-Video Generation : Turn images into dynamic video content using am image as reference input.
2. Video-to-Video Editing : Vace modify existing videos with precision by making an entire change to a provided video, such as colorization, stylization, controllable generation, etc.
3. Masked Video Editing : Seamlessly remove or replace elements within the provided 3D regions of interest (3D ROI), seamlessly blending in with the other unchanged regions.
4. Motion & Pose Transfer : Vace helps in bringing static subjects to life.
5. Canvas & Temporal Extension : Expand video frames effortlessly.
6. Colorization & Structure Transfer : Convert black-and-white to color, adjust depth, and more.
7. Task Composition : Combine multiple edits in a single workflow.

How It Works

VACE uses a Video Condition Unit (VCU) to unify inputs like text, images, videos, and masks, making it adaptable to different video tasks. It also employs a Context Adapter, ensuring edits remain visually consistent across frames. Unlike single-task models, VACE’s architecture allows it to perform multiple editing functions simultaneously, reducing the need for separate tools.

Proven Performance

Benchmarked against leading video AI models, VACE consistently delivers high-quality outputs. It outperforms many task-specific models and even rivals commercial solutions in flexibility, efficiency, and accuracy.

For content creators, filmmakers, and digital marketers, VACE removes the friction from video production. No more switching between tools or dealing with inconsistent AI results because everything you need is now in one model.
