AnimateDiff
AnimateDiff is an open-source project that turns ordinary Stable Diffusion image models into animation generators. A small add-on module teaches your favorite checkpoint to produce short, consistent video clips, and it runs locally in ComfyUI and Automatic1111.

What is AnimateDiff?
AnimateDiff is a clever piece of AI engineering from a team at Shanghai AI Laboratory. Normally, generating AI video means training a huge model from scratch. AnimateDiff instead inserts a lightweight motion module into an existing Stable Diffusion checkpoint, teaching it to animate without losing the image quality you already know.
The practical result: any of the thousands of community Stable Diffusion models can generate short clips. Use your favorite anime model and get anime clips; use a realistic model and get realistic motion. The technique was introduced in a 2023 paper and released openly.
It works in the major local tools: ComfyUI, Automatic1111's WebUI, and the Hugging Face Diffusers library. You download a motion module once, plug it in, and generate clips of 16 frames or more with prompts, ControlNet and other extensions.
Key Features
- Motion module compatible with most Stable Diffusion 1.5 and SDXL checkpoints
- Generate animation from text prompts or image-to-video workflows
- ControlNet support for shape and pose control across frames
- Works in ComfyUI, Automatic1111 and Diffusers
- Community motion modules and LoRA companions
- Free and open source with an active community
How to get started
The easiest path is ComfyUI: install the AnimateDiff nodes through the ComfyUI Manager, download a motion module from Hugging Face, and connect it in a simple workflow. If you already use ComfyUI, you are minutes from your first clip.
In Automatic1111, install the sd-webui-animatediff extension and drop the motion module into the right folder. Then prompt like you would for an image, and the extension generates a video. Start with short clips and simple prompts while you learn.
- Install ComfyUI or Automatic1111
- Install the AnimateDiff extension or nodes
- Download a motion module from Hugging Face
- Load a Stable Diffusion checkpoint you like
- Prompt and generate your first short clip
- Experiment with ControlNet and frame counts
Use cases
- AI anime clips and fan art animation
- Experimental music videos and short films
- Concept animation for games and design
- Learning how diffusion models handle motion
- Batch-generating short motion loops for social content
Pricing and licensing
AnimateDiff itself is free and open source under the Apache 2.0 license, so there is no cost to use it. You only need a computer with a capable GPU, since generating video is far heavier than generating single images.
Keep the base model licenses in mind: the Stable Diffusion checkpoints you animate come with their own terms, and some community models restrict commercial use. Check the license of the checkpoint before shipping generated content.
Pros and cons
AnimateDiff is astonishing value: free, local, and compatible with the entire Stable Diffusion ecosystem. Because motion is added by a module, you keep the exact art style of your favorite model, and the community around it is creative and active.
The limitations are honest ones. Clips are short, consistency can wobble over longer sequences, and quality depends heavily on your hardware and prompt. It also animates in a diffusion style, so it is not a replacement for deliberate, hand-crafted animation.
