Download ffmpeg-static

Download and decompress ffmpeg-static, then

export FFMPEG_PATH=/path/to/ffmpeg-4.4-amd64-static

Download pretrained weights

git lfs install
git clone https://huggingface.co/BadToBest/EchoMimicV2 pretrained_weights

The pretrained_weights is organized as follows.

./pretrained_weights/
├── denoising_unet.pth
├── reference_unet.pth
├── motion_module.pth
├── pose_encoder.pth
├── sd-vae-ft-mse
│   └── ...
└── audio_processor
    └── tiny.pt

In which denoising_unet.pth / reference_unet.pth / motion_module.pth / pose_encoder.pth are the main checkpoints of EchoMimic. Other models in this hub can be also downloaded from it's original hub, thanks to their brilliant works:

Inference on Demo

Run the gradio:

python app.py

Run the python inference script:

python infer.py --config='./configs/prompts/infer.yaml'

Run the python inference script for accelerated version. Make sure to check out the configuration for accelerated inference:

python infer_acc.py --config='./configs/prompts/infer_acc.yaml'

EMTD Dataset

Download dataset:

python ./EMTD_dataset/download.py

Slice dataset:

bash ./EMTD_dataset/slice.sh

Process dataset:

python ./EMTD_dataset/preprocess.py

Make sure to check out the discussions to learn how to start the inference.
