AnimateDiff: bring motion to any Stable Diffusion model
In one sentence Shanghai AI Lab publishes AnimateDiff: a plug-in motion module that adds temporal consistency to any existing SD checkpoint, turning every image-only model into a video generator without retraining it.
Stable Diffusion in 2023 had a problem: every fine-tune, every checkpoint, every LoRA produced beautiful but static images. To animate them, you had to start over with a dedicated video model.
AnimateDiff solves this with a plug-in approach: an additional module — the motion module — is inserted into the existing neural network. This module learns only movement, not style. Once trained on a large video dataset, it can be plugged into any SD model without modifying it.
The result: if you have a checkpoint generating gorgeous anime-style landscapes, you can animate it immediately. If you have one trained on fantasy illustrations, it works there too. All of the SD ecosystem's creativity becomes animatable in minutes. This was the main engine of open-source video generation throughout 2023-2024.
