News

• 2025/02/27: Our paper has been accepted to CVPR 2025.
• 2025/01/27: Release training data on HuggingFace. The collection comprises over 70 hours of talking-head videos, complemented by an additional 50 hours of dynamic video clips featuring vibrant foregrounds and backgrounds.

⚙️ Installation

• System requirement: Ubuntu 20.04/Ubuntu 22.04, Cuda 12.1
• Tested GPUs: H100

Download the codes:

  git clone https://github.com/fudan-generative-vision/hallo3
  cd hallo3

Create conda environment:

  conda create -n hallo python=3.10
  conda activate hallo

Install packages with pip

  pip install -r requirements.txt

Besides, ffmpeg is also needed:

  apt-get install ffmpeg

Download Pretrained Models

You can easily get all pretrained models required by inference from our HuggingFace repo.

Using huggingface-cli to download the models:

cd $ProjectRootDir
pip install "huggingface_hub[cli]"
huggingface-cli download fudan-generative-ai/hallo3 --local-dir ./pretrained_models

Or you can download them separately from their source repo:

• hallo3: Our checkpoints.
• Cogvidex: Cogvideox-5b-i2v pretrained model, consisting of transformer and 3d vae
• t5-v1_1-xxl: text encoder, you can download from text_encoder and tokenizer
• audio_separator: Kim Vocal_2 MDX-Net vocal removal model.
• wav2vec: wav audio to vector model from Facebook.
• insightface: 2D and 3D Face Analysis placed into pretrained_models/face_analysis/models/. (Thanks to deepinsight)
• face landmarker: Face detection & mesh model from mediapipe 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

Gradio UI

To run the Gradio UI simply run hallo3/app.py:

python hallo3/app.py

Batch

Simply to run the scripts/inference_long_batch.sh:

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.

Training

Prepare data for training

Begin your data-exploration by downloading the training dataset from the HuggingFace Dataset Repo. This dataset contains over 70 hours of talking-head videos, focusing on the speaker's face and speech, and more than 50 wild-scene clips from various real-world settings. After downloading, simply unzip all the .tgz files to access the data and start your projects and organize them into the following directory structure:

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 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:

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

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

Start training with the following command:

# 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.
