ToonCrafter AI
Generate fluid cartoon animations between keyframes with generative AI interpolation, sketch colorization, and sketch-guided motion synthesis.
About ToonCrafter AI
ToonCrafter AI is a generative cartoon interpolation tool designed to produce fluid animated transitions between static cartoon frames. Built using pre-trained image-to-video diffusion models, the tool takes two anchor keyframes representing the beginning and end of a sequence, along with an optional text prompt, and generates smooth in-between animation frames to construct a cohesive visual motion clip. Beyond basic two-frame interpolation, the platform supports several specialized workflows. Users can perform cartoon sketch interpolation to blend rough drawings, execute reference-based sketch colorization to apply consistent color palettes from reference artwork, and use sparse sketch-guided generation to retain precise control over character poses and motion paths. Outputs are rendered as 16-frame video clips at resolutions up to 512x320, with adjustable DDIM sampling steps to balance inference speed and render fidelity. ToonCrafter AI is intended for independent animators, storyboard artists, content creators, and creative directors looking to speed up the traditional inbetweening process. By automating the labor-intensive task of drawing transition frames, it enables creators and educators to prototype animated scenes or bring conceptual illustrations to life without manual frame-by-frame rendering. Developed as a research collaboration between The Chinese University of Hong Kong, City University of Hong Kong, and Tencent AI Lab, ToonCrafter distinguishes itself through its open-source foundation under the Apache-2.0 license. Users can test the system through web and Gradio demos or deploy it locally in custom Python environments for complete control over their rendering pipeline.

ToonCrafter AI FAQs
What is ToonCrafter AI?
ToonCrafter AI is a generative cartoon interpolation tool that uses pre-trained image-to-video diffusion models. It creates fluid animations and transitions by generating the in-between frames between two cartoon images.
What video resolution and frame count does ToonCrafter AI support?
ToonCrafter AI generates animations at a resolution of up to 512x320 and 16 frames. Inference performance and generation time can be adjusted by tuning the number of DDIM steps.
Can I run ToonCrafter AI locally?
Yes, ToonCrafter AI can be run locally using an Anaconda virtual environment with Python packages installed from requirements.txt. Users can download pre-trained weights and run the provided scripts or Gradio interface.
Is ToonCrafter AI open source?
Yes, ToonCrafter AI is open-source software released under the Apache-2.0 license, allowing developers to inspect code, contribute, and integrate it into other pipelines.
What are the known limitations of ToonCrafter AI?
The model may occasionally struggle with fully understanding image semantics, which can result in incorrect or unnatural motion paths. It is primarily an open-source research tool and may not cover every commercial animation requirement.
What creative tasks can ToonCrafter AI perform besides frame interpolation?
In addition to cartoon sketch interpolation, ToonCrafter supports reference-based sketch colorization and sparse sketch-guided animation generation for directional control.
