> Tianwei Yin*, Qiang Zhang*, Richard Zhang, William T. Freeman, Frédo Durand, Eli Shechtman, Xun Huang (* equal contribution)        


## Environment Setup 

```bash
git clone https://github.com/tianweiy/CausVid  && cd CausVid
conda create -n causvid python=3.10 -y
conda activate causvid
pip install torch torchvision 
pip install -r requirements.txt 
python setup.py develop
```

Also download the Wan base models from [here](https://github.com/Wan-Video/Wan2.1) and save it to wan_models/Wan2.1-T2V-1.3B/

## Inference Example 

First download the checkpoints: [Autoregressive Model](https://huggingface.co/tianweiy/CausVid/tree/main/autoregressive_checkpoint), [Bidirectional Model 1](https://huggingface.co/tianweiy/CausVid/tree/main/bidirectional_checkpoint1) or [Bidirectional Model 2](https://huggingface.co/tianweiy/CausVid/tree/main/bidirectional_checkpoint2) (performs slightly better). 

### Autoregressive 3-step 5-second Video Generation  

```bash 
python minimal_inference/autoregressive_inference.py --config_path configs/wan_causal_dmd.yaml --checkpoint_folder XXX  --output_folder XXX   --prompt_file_path XXX 
```

### Autoregressive 3-step long Video Generation

```bash 
python minimal_inference/longvideo_autoregressive_inference.py --config_path configs/wan_causal_dmd.yaml --checkpoint_folder XXX  --output_folder XXX   --prompt_file_path XXX   --num_rollout XXX 
```

### Bidirectional 3-step 5-second Video Generation

```bash 
python minimal_inference/bidirectional_inference.py --config_path configs/wan_bidirectional_dmd_from_scratch.yaml --checkpoint_folder XXX  --output_folder XXX   --prompt_file_path XXX 
```
