Cinemo: Consistent and Controllable Image Animation with Motion Diffusion Models
_{Official PyTorch Implementation}

This repo contains pre-trained weights, and sampling code for our paper exploring image animation with motion diffusion models (Cinemo). You can find more visualizations on our project page.

In this project, we propose a novel method called Cinemo, which can perform motion-controllable image animation with strong consistency and smoothness. To improve motion smoothness, Cinemo learns the distribution of motion residuals, rather than directly generating subsequent frames. Additionally, a structural similarity index-based method is proposed to control the motion intensity. Furthermore, we propose a noise refinement technique based on discrete cosine transformation to ensure temporal consistency. These three methods help Cinemo generate highly consistent, smooth, and motion-controlled image animation results. Compared to previous methods, Cinemo offers simpler and more precise user control and better generative performance.

News

(🔥 New) Jul. 23, 2024. 💥 Our paper is released on arxiv.
(🔥 New) Jun. 2, 2024. 💥 The inference code is released. The checkpoint can be found here.

Setup

First, download and set up the repo:

git clone https://github.com/maxin-cn/Cinemo
cd Cinemo

We provide an environment.yml file that can be used to create a Conda environment. If you only want to run pre-trained models locally on CPU, you can remove the cudatoolkit and pytorch-cuda requirements from the file.

conda env create -f environment.yml
conda activate cinemo

Animation

You can sample from our pre-trained Cinemo models with animation.py. Weights for our pre-trained Cinemo model can be found here. The script has various arguments for adjusting sampling steps, changing the classifier-free guidance scale, etc:

bash pipelines/animation.sh

All related checkpoints will download automatically and then you will get the following results,

Input image	Output video	Input image	Output video

Other Applications

You can also utilize Cinemo for other applications, such as motion transfer and video editing:

bash pipelines/video_editing.sh

All related checkpoints will download automatically and you will get the following results,

Input video	First frame	Edited first frame	Output video
