CausVid Model Card

From Slow Bidirectional to Fast Autoregressive Video Diffusion Models,
Tianwei Yin*, Qiang Zhang*, Richard Zhang, William T. Freeman, Frédo Durand, Eli Shechtman, Xun Huang (* equal contribution)

Environment Setup

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 and save it to wan_models/Wan2.1-T2V-1.3B/

Inference Example

First download the checkpoints: Autoregressive Model, Bidirectional Model 1 or Bidirectional Model 2 (performs slightly better).

Autoregressive 3-step 5-second Video Generation

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

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

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
