## Download Models

### Step 1: Download HunyuanVideo Model
Download the HunyuanVideo model and place it in the `ckpts` directory:
```bash
huggingface-cli download tencent/HunyuanVideo --local-dir ./ckpts
```

### Step 2: Download LLaVA Model
Download the LLaVA model and preprocess it:
```bash
cd ckpts
huggingface-cli download xtuner/llava-llama-3-8b-v1_1-transformers --local-dir ./llava-llama-3-8b-v1_1-transformers
wget https://raw.githubusercontent.com/Tencent/HunyuanVideo/refs/heads/main/hyvideo/utils/preprocess_text_encoder_tokenizer_utils.py
python preprocess_text_encoder_tokenizer_utils.py --input_dir llava-llama-3-8b-v1_1-transformers --output_dir text_encoder
```

### Step 3: Download CLIP Model
Download the CLIP model for the text encoder:
```bash
huggingface-cli download openai/clip-vit-large-patch14 --local-dir ./text_encoder_2
```

## Notes
- Ensure you have sufficient GPU resources for video generation.
- Adjust the `--video_size`, `--video_length`, and `--infer_steps` parameters as needed for different output qualities and lengths.
- The `--prompt` parameter can be modified to generate videos with different scenes or actions.
