## 🔆 Introduction

🤗🤗🤗 VideoCrafter is an open-source video generation and editing toolbox for crafting video content.   
It currently includes the Text2Video and Image2Video models:

### 1. Generic Text-to-video Generation

## ⚙️ Setup

### 1. Install Environment via Anaconda (Recommended)
```bash
conda create -n videocrafter python=3.8.5
conda activate videocrafter
pip install -r requirements.txt
```


## 💫 Inference 
### 1. Text-to-Video

1) Download pretrained T2V models via [Hugging Face](https://huggingface.co/VideoCrafter/VideoCrafter2/blob/main/model.ckpt), and put the `model.ckpt` in `checkpoints/base_512_v2/model.ckpt`.
2) Input the following commands in terminal.
```bash
  sh scripts/run_text2video.sh
```

### 2. Image-to-Video

1) Download pretrained I2V models via [Hugging Face](https://huggingface.co/VideoCrafter/Image2Video-512-v1.0/blob/main/model.ckpt), and put the `model.ckpt` in `checkpoints/i2v_512_v1/model.ckpt`.
2) Input the following commands in terminal.
```bash
  sh scripts/run_image2video.sh
```

### 3. Local Gradio demo

1. Download the pretrained T2V and I2V models and put them in the corresponding directory according to the previous guidelines.
2. Input the following commands in terminal.
```bash
  python gradio_app.py
```
