Image Conductor

This repository is the official implementation of Image Conductor. It is a novel approach for precise and fine-grained control of camera transitions and object movements in interactive video synthesis.

Filmmaking and animation production often require sophisticated techniques for coordinating camera transitions and object movements, typically involving labor-intensive real-world capturing. Despite advancements in generative AI for video creation, achieving precise control over motion for interactive video asset generation remains challenging. To this end, we propose Image Conductor, a method for precise control of camera transitions and object movements to generate video assets from a single image. An well-cultivated training strategy is proposed to separate distinct camera and object motion by camera LoRA weights and object LoRA weights. To further address cinematographic variations from ill-posed trajectories, we introduce a camera-free guidance technique during inference, enhancing object movements while eliminating camera transitions. Additionally, we develop a trajectory-oriented video motion data curation pipeline for training.

🧙 Method Overview

<div align="center"> <img src='./__assets__/method.png'/> </div> To address the lack of large-scale annotated video data, we first design a data construction pipeline to create a consistent video dataset with appropriate motion. Then, an well-cultivated two-stage training scheme is proposed to derive motion-controllable video ControlNet, which can separate camera tansitions and object movements based on distinct lora weights.

🔧 Preparations

Setup repository and conda environment

Adjust the PyTorch version according to the CUDA version you are using. CUDA 12.1 for our case.

git clone https://github.com/liyaowei-stu/ImageConductor.git
cd ImageConductor

conda create -n imageconductor python=3.10 -y
conda activate imageconductor
pip install -r requirements.txt

Prepare model weights

Download the weights of Stable-Diffusion v1.5 SDv1.5 and put it to ./models.
Download the weights of ImageConductor imageconductor_v1 and put it to ./models.
(optional) Manually download the community .safetensors models from CivitAI, and save them to models/personalized. The model structure should be like:

|-- models
    |-- stable-diffusion-v1-5
        |-- model_index.json
        |-- vae
        |-- text_encoder
        |-- ...
    |-- unet.ckpt
    |-- image_controlnet.ckpt
    |-- flow_controlnet.ckpt
    |-- personalized
        |-- helloobjects_V12c.safetensors
        |-- TUSUN.safetensors
        |-- ...
