MegActor Features:

Usability: animates a portrait with video while ensuring consistent motion.

Reproducibility: fully open-source and trained on publicly available datasets.

Efficiency: ⚡200 V100 hours of training to achieve pleasant motions on portraits.

Overview

MegActor is an intermediate-representation-free portrait animator that uses the original video, rather than intermediate features, as the driving factor to generate realistic and vivid talking head videos. Specifically, we utilize two UNets: one extracts the identity and background features from the source image, while the other accurately generates and integrates motion features directly derived from the original videos. MegActor can be trained on low-quality, publicly available datasets and excels in facial expressiveness, pose diversity, subtle controllability, and visual quality.

Preparation

• Environments

  Detailed environment settings should be found with environment.yaml

  • Linux

    conda env create -f environment.yaml
    pip install -U openmim
    
    mim install mmengine
    mim install "mmcv>=2.0.1"
    mim install "mmdet>=3.1.0"
    mim install "mmpose>=1.1.0"
    
    conda install -c conda-forge cudatoolkit-dev -y
    

• Dataset.

  • For a detailed description of the data processing procedure, please refer to the accompanying below. Data Process Pipeline

• Pretrained weights

  Please find our pretrained weights at https://huggingface.co/HVSiniX/RawVideoDriven. Or simply use

  git clone https://huggingface.co/HVSiniX/RawVideoDriven && ln -s RawVideoDriven/weights weights

Training

We currently support two-stage training on single node machines.

Stage1(Image training):

bash train.sh train.py ./configs/train/train_stage1.yaml {number of gpus on this node}

Stage2(Video training):

bash train.sh train.py ./configs/train/train_stage2.yaml {number of gpus on this node}

Inference

Currently only single-GPU inference is supported. We highly recommend that you use --contour-preserve arg the better preserve the shape of the source face.

CUDA_VISIBLE_DEVICES=0 python eval.py --config configs/inference/inference.yaml --source {source image path} --driver {driving video path} --contour-preserve

Demo

For gradio interface, please run

python demo/run_gradio.py
