Deforum is the official extension for AUTOMATIC1111’s Stable Diffusion WebUI that turns still-image generation into animation, published on GitHub with about 2,900 stars. It is one of the most widely used tools for creating AI-generated videos, music visualizers and morphing art sequences.
Deforum adds a full animation system on top of Stable Diffusion: it renders sequences of frames while applying camera motion, zoom, rotation and 3D transformations between them, guided by prompt schedules that can change the scene over time. Keyframe-based settings let artists choreograph movement precisely, and features such as optical-flow cadence, noise scheduling and video input modes support everything from short loops to long music videos. The extension installs directly into the WebUI’s extensions folder and exposes all controls in the browser interface. The codebase was last actively updated in 2024. A large community wiki, FAQ and countless shared setting files make it easy to learn, and Deforum pieces are a staple of AI art festivals and VJ sets.
Deforum is completely free and open source. There are no paid tiers; you install it into your own Stable Diffusion WebUI setup and generate on your own GPU.
Deforum is for digital artists, musicians and creators who want to produce animated visuals and music videos with Stable Diffusion rather than single still images.
