### 📥 Download Pretrained Models

You can easily get all pretrained models required by inference from our [HuggingFace repo](https://huggingface.co/fudan-generative-ai/hallo3).

Using `huggingface-cli` to download the models:

```shell
cd $ProjectRootDir
pip install huggingface-cli
huggingface-cli download fudan-generative-ai/hallo3 --local-dir ./pretrained_models
```

Or you can download them separately from their source repo:

- [hallo3](https://huggingface.co/fudan-generative-ai/hallo3/tree/main/hallo3): Our checkpoints.
- [Cogvidex](https://github.com/THUDM/CogVideo): Cogvideox-5b-i2v pretrained model, consisting of transformer and 3d vae
- [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)
- [audio_separator](https://huggingface.co/huangjackson/Kim_Vocal_2): Kim Vocal_2 MDX-Net vocal removal model.
- [wav2vec](https://huggingface.co/facebook/wav2vec2-base-960h): wav audio to vector model from [Facebook](https://huggingface.co/facebook/wav2vec2-base-960h).
- [insightface](https://github.com/deepinsight/insightface/tree/master/python-package#model-zoo): 2D and 3D Face Analysis placed into `pretrained_models/face_analysis/models/`. (_Thanks to deepinsight_)
- [face landmarker](https://storage.googleapis.com/mediapipe-models/face_landmarker/face_landmarker/float16/1/face_landmarker.task): Face detection & mesh model from [mediapipe](https://ai.google.dev/edge/mediapipe/solutions/vision/face_landmarker#models) placed into `pretrained_models/face_analysis/models`.

Finally, these pretrained models should be organized as follows:

### 🛠️ Prepare Inference Data

Hallo3 has a few simple requirements for the input data of inference:
1. Reference image must be 1:1 or 3:2 aspect ratio.
2. Driving audio must be in WAV format.
3. Audio must be in English since our training datasets are only in this language.
4. Ensure the vocals of audio are clear; background music is acceptable.

### 🎮 Run Inference

Simply to run the `scripts/inference_long_batch.sh`:

```bash
bash scripts/inference_long_batch.sh ./examples/inference/input.txt ./output
```

Animation results will be saved at `./output`. You can find more examples for inference at [examples folder](https://github.com/fudan-generative-vision/hallo3/tree/main/examples).


## Training

#### prepare data for training
Organize your raw videos into the following directory structure:
```text
dataset_name/
|-- videos/
|   |-- 0001.mp4
|   |-- 0002.mp4
|   `-- 0003.mp4
|-- caption/
|   |-- 0001.txt
|   |-- 0002.txt
|   `-- 0003.txt
```
You can use any dataset_name, but ensure the videos directory and caption directory are named as shown above.

Next, process the videos with the following commands:
```bash
bash scripts/data_preprocess.sh {dataset_name} {parallelism} {rank} {output_name}
```

#### Training

Update the data meta path settings in the configuration YAML files, `configs/sft_s1.yaml` and `configs/sft_s2.yaml`:

```yaml
#sft_s1.yaml
train_data: [
    "./data/output_name.json"
]

#sft_s2.yaml
train_data: [
    "./data/output_name.json"
]
```

Start training with the following command:
```bash
# stage1
bash scripts/finetune_multi_gpus_s1.sh

# stage2
bash scripts/finetune_multi_gpus_s2.sh
```

## ⚠️ Social Risks and Mitigations

The development of portrait image animation technologies driven by audio inputs poses social risks, such as the ethical implications of creating realistic portraits that could be misused for deepfakes. To mitigate these risks, it is crucial to establish ethical guidelines and responsible use practices. Privacy and consent concerns also arise from using individuals' images and voices. Addressing these involves transparent data usage policies, informed consent, and safeguarding privacy rights. By addressing these risks and implementing mitigations, the research aims to ensure the responsible and ethical development of this technology.
