HunyuanPortrait
Implicit Condition Control for Enhanced Portrait Animation

📜 Requirements

• An NVIDIA 3090 GPU with CUDA support is required.
  • The model is tested on a single 24G GPU.
• Tested operating system: Linux

Installation

git clone https://github.com/Tencent-Hunyuan/HunyuanPortrait
pip3 install torch torchvision torchaudio
pip3 install -r requirements.txt

Download

All models are stored in pretrained_weights by default:

pip3 install "huggingface_hub[cli]"
cd pretrained_weights
huggingface-cli download --resume-download stabilityai/stable-video-diffusion-img2vid-xt --local-dir . --include "*.json"
wget -c https://huggingface.co/LeonJoe13/Sonic/resolve/main/yoloface_v5m.pt
wget -c https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt/resolve/main/vae/diffusion_pytorch_model.fp16.safetensors -P vae
wget -c https://huggingface.co/FoivosPar/Arc2Face/resolve/da2f1e9aa3954dad093213acfc9ae75a68da6ffd/arcface.onnx
huggingface-cli download --resume-download tencent/HunyuanPortrait --local-dir hyportrait

    --image_path $image_path

Framework

TL;DR:

HunyuanPortrait is a diffusion-based framework for generating lifelike, temporally consistent portrait animations by decoupling identity and motion using pre-trained encoders. It encodes driving video expressions/poses into implicit control signals, injects them via attention-based adapters into a stabilized diffusion backbone, enabling detailed and style-flexible animation from a single reference image. The method outperforms existing approaches in controllability and coherence.
