SEINE

This repository is the official implementation of SEINE:

SEINE: Short-to-Long Video Diffusion Model for Generative Transition and Prediction (ICLR2024)

SEINE is a video diffusion model and is part of the video generation system Vchitect. You can also check our Text-to-Video (T2V) framework LaVie.

Setup

Prepare Environment

conda create -n seine python==3.9.16
conda activate seine
pip install -r requirement.txt

Download our model and T2I base model

Our model is based on Stable diffusion v1.4, you may download Stable Diffusion v1-4 to the director of pretrained . Download our model checkpoint (from google drive or hugging face) and save to the directory of pretrained

Now under ./pretrained, you should be able to see the following:

├── pretrained
│   ├── seine.pt
│   ├── stable-diffusion-v1-4
│   │   ├── ...
└── └── ├── ...
        ├── ...

Usage

Inference for I2V

Run the following command to get the I2V results:

python sample_scripts/with_mask_sample.py --config configs/sample_i2v.yaml

The generated video will be saved in ./results/i2v.

More Details

You may modify ./configs/sample_i2v.yaml to change the generation conditions. For example:

ckpt is used to specify a model checkpoint.

text_prompt is used to describe the content of the video.

input_path is used to specify the path to the image.

Inference for Transition

python sample_scripts/with_mask_sample.py --config configs/sample_transition.yaml

The generated video will be saved in ./results/transition.
