## 🎬 Pipeline

MTVCraft is a framework for generating videos with synchronized audio from a single text prompt, exploring a potential pipeline for creating general audio-visual content.

Specifically, the framework consists of a multi-stage pipeline. First, MTVCraft employs the [Qwen3](https://bailian.console.aliyun.com/?tab=model#/model-market/detail/qwen3?modelGroup=qwen3) to interpret the user's initial prompt, deconstructing it into separate descriptions for three audio categories: human speech, sound effects, and background music. Subsequently, these descriptions are fed into [ElevenLabs](https://elevenlabs.io/) to synthesize the corresponding audio tracks. Finally, these generated audio tracks serve as conditions to guide the [MTV framework](https://arxiv.org/pdf/2506.08003) in generating a video that is temporally synchronized with the sound.

Notably, both Qwen3 and ElevenLabs can be replaced by available alternatives with similar capabilities.

## ⚙️ Installation

For CUDA 12.1, you can install the dependencies with the following commands. Otherwise, you need to manually install `torch`, `torchvision` , `torchaudio` and `xformers`.

Download the codes:

```bash
git clone https://github.com/suimuc/MTVCraft
cd MTVCraft
```

Create conda environment:

```bash
conda create -n mtv python=3.10
conda activate mtv
```

Install packages with `pip`

```bash
pip install -r requirements.txt
```

Besides, ffmpeg is also needed:

```bash
apt-get install ffmpeg
```

## 📥 Download Pretrained Models

You can easily get all pretrained models required by inference from our [HuggingFace repo](https://huggingface.co/BAAI/MTVCraft).

Using `huggingface-cli` to download the models:

```shell
cd $ProjectRootDir
pip install "huggingface_hub[cli]"
huggingface-cli download BAAI/MTVCraft --local-dir ./pretrained_models
```

Or you can download them separately from their source repo:

- [mtv](https://huggingface.co/BAAI/MTVCraft/tree/main/mtv): Our checkpoints
- [t5-v1_1-xxl](https://huggingface.co/google/t5-v1_1-xxl): text encoder, you can download from [text_encoder](https://huggingface.co/THUDM/CogVideoX-2b/tree/main/text_encoder) and [tokenizer](https://huggingface.co/THUDM/CogVideoX-2b/tree/main/tokenizer)
- [vae](https://huggingface.co/THUDM/CogVideoX1.5-5B-SAT/tree/main/vae): Cogvideox-5b pretrained 3d vae
- [wav2vec](https://huggingface.co/facebook/wav2vec2-base-960h): wav audio to vector model from [Facebook](https://huggingface.co/facebook/wav2vec2-base-960h)

Finally, these pretrained models should be organized as follows:

```text
./pretrained_models/
|-- mtv
|   |--single/
|   |   |-- 1/
|   |     |-- mp_rank_00_model_states.pt

    `-- vocab.json
```

## 🎮 Run Inference

#### API Setup (Required)
Before running the inference script, make sure to configure your API keys in the file `mtv/utils.py`. Edit the following section:
```python
# mtv/utils.py

qwen_model_name = "qwen-plus"  # or another model name you prefer
qwen_api_key = "YOUR_QWEN_API_KEY"  # replace with your actual Qwen API key

client = OpenAI(
    api_key=qwen_api_key,
    base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
)

elevenlabs = ElevenLabs(
    api_key="YOUR_ELEVENLABS_API_KEY",  # replace with your actual ElevenLabs API key
)
```

#### Batch

Once the API keys are set, you can run inference using the provided script:

```bash
bash scripts/inference_long.sh ./examples/samples.txt ouput_dir
```
This will read the input prompts from `./examples/samples.txt` and the results will be saved at `./output`.

#### Gradio UI
To run the Gradio UI simply run:
```bash
bash scripts/app.sh ouput_dir
```
