• Completeness, encompassing all common components for video generation.
• Excellent performance, featuring powerful pre-trained models in multiple tasks.

Installation

conda create -n vgen python=3.8
conda activate vgen
pip install torch==1.12.0+cu113 torchvision==0.13.0+cu113 torchaudio==0.12.0 --extra-index-url https://download.pytorch.org/whl/cu113
pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

You also need to ensure that your system has installed the ffmpeg command. If it is not installed, you can install it using the following command:

sudo apt-get update && apt-get install ffmpeg libsm6 libxext6  -y

Datasets

We have provided a demo dataset that includes images and videos, along with their lists in data.

Please note that the demo images used here are for testing purposes and were not included in the training.

Clone codeb

git clone https://github.com/damo-vilab/i2vgen-xl.git
cd i2vgen-xl

Getting Started with VGen

(1) Train your text-to-video model

Executing the following command to enable distributed training is as easy as that.

python train_net.py --cfg configs/t2v_train.yaml

In the t2v_train.yaml configuration file, you can specify the data, adjust the video-to-image ratio using frame_lens, and validate your ideas with different Diffusion settings, and so on.

• Before the training, you can download any of our open-source models for initialization. Our codebase supports custom initialization and grad_scale settings, all of which are included in the Pretrain item in yaml file.
• During the training, you can view the saved models and intermediate inference results in the workspace/experiments/t2v_traindirectory.

After the training is completed, you can perform inference on the model using the following command.

python inference.py --cfg configs/t2v_infer.yaml

Then you can find the videos you generated in the workspace/experiments/test_img_01 directory. For specific configurations such as data, models, seed, etc., please refer to the t2v_infer.yaml file.

(2) Run the I2VGen-XL model

(i) Download model and test data:

!pip install modelscope
from modelscope.hub.snapshot_download import snapshot_download
model_dir = snapshot_download('damo/I2VGen-XL', cache_dir='models/', revision='v1.0.0')

or you can also download it through HuggingFace (https://huggingface.co/damo-vilab/i2vgen-xl):

# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install
git clone https://huggingface.co/damo-vilab/i2vgen-xl

(ii) Run the following command:

python inference.py --cfg configs/i2vgen_xl_infer.yaml

or you can run:

python inference.py --cfg configs/i2vgen_xl_infer.yaml  test_list_path data/test_list_for_i2vgen.txt test_model models/i2vgen_xl_00854500.pth

The test_list_path represents the input image path and its corresponding caption. Please refer to the specific format and suggestions within demo file data/test_list_for_i2vgen.txt. test_model is the path for loading the model. In a few minutes, you can retrieve the high-definition video you wish to create from the workspace/experiments/test_list_for_i2vgen directory. At present, we find that the current model performs inadequately on anime images and images with a black background due to the lack of relevant training data. We are consistently working to optimize it.
