github huggingface Project(comming soon) Technical report (comming soon)

We introduce MuseTalk, a real-time high quality lip-syncing model (30fps+ on an NVIDIA Tesla V100). MuseTalk can be applied with input videos, e.g., generated by MuseV, as a complete virtual human solution.

Overview

MuseTalk is a real-time high quality audio-driven lip-syncing model trained in the latent space of ft-mse-vae, which

1. modifies an unseen face according to the input audio, with a size of face region of 256 x 256.
2. supports audio in various languages, such as Chinese, English, and Japanese.
3. supports real-time inference with 30fps+ on an NVIDIA Tesla V100.
4. supports modification of the center point of the face region proposes, which SIGNIFICANTLY affects generation results.
5. checkpoint available trained on the HDTF dataset.
6. training codes (comming soon).

News

• [04/02/2024] Released MuseTalk project and pretrained models.

Model

MuseTalk was trained in latent spaces, where the images were encoded by a freezed VAE. The audio was encoded by a freezed whisper-tiny model. The architecture of the generation network was borrowed from the UNet of the stable-diffusion-v1-4, where the audio embeddings were fused to the image embeddings by cross-attention.

Cases

MuseV + MuseTalk make human photos alive！

Getting Started

We provide a detailed tutorial about the installation and the basic usage of MuseTalk for new users:

Installation

To prepare the Python environment and install additional packages such as opencv, diffusers, mmcv, etc., please follow the steps below:

Build environment

We recommend a python version >=3.10 and cuda version =11.7. Then build environment as follows:

pip install -r requirements.txt

whisper

install whisper to extract audio feature (only encoder)

pip install --editable ./musetalk/whisper

mmlab packages

pip install --no-cache-dir -U openmim 
mim install mmengine 
mim install "mmcv>=2.0.1" 
mim install "mmdet>=3.1.0" 
mim install "mmpose>=1.1.0" 

Download ffmpeg-static

Download the ffmpeg-static and

export FFMPEG_PATH=/path/to/ffmpeg

for example:

export FFMPEG_PATH=/musetalk/ffmpeg-4.4-amd64-static

Download weights

You can download weights manually as follows:

1. Download our trained weights.

2. Download the weights of other components:

   • sd-vae-ft-mse
   • whisper
   • dwpose
   • face-parse-bisent
   • resnet18

Finally, these weights should be organized in models as follows:

./models/
├── musetalk
│   └── musetalk.json
│   └── pytorch_model.bin
├── dwpose
│   └── dw-ll_ucoco_384.pth
├── face-parse-bisent
│   ├── 79999_iter.pth
│   └── resnet18-5c106cde.pth
├── sd-vae-ft-mse
│   ├── config.json
│   └── diffusion_pytorch_model.bin
└── whisper
    └── tiny.pt

Quickstart

Inference

Here, we provide the inference script.

python -m scripts.inference --inference_config configs/inference/test.yaml 

configs/inference/test.yaml is the path to the inference configuration file, including video_path and audio_path. The video_path should be either a video file or a directory of images.

Use of bbox_shift to have adjustable results

:mag_right: We have found that upper-bound of the mask has an important impact on mouth openness. Thus, to control the mask region, we suggest using the bbox_shift parameter. Positive values (moving towards the lower half) increase mouth openness, while negative values (moving towards the upper half) decrease mouth openness.

You can start by running with the default configuration to obtain the adjustable value range, and then re-run the script within this range.

For example, in the case of Xinying Sun, after running the default configuration, it shows that the adjustable value rage is [-9, 9]. Then, to decrease the mouth openness, we set the value to be -7.

python -m scripts.inference --inference_config configs/inference/test.yaml --bbox_shift -7 

:pushpin: More technical details can be found in bbox_shift.

Combining MuseV and MuseTalk

As a complete solution to virtual human generation, you are suggested to first apply MuseV to generate a video (text-to-video, image-to-video or pose-to-video) by referring this. Then, you can use MuseTalk to generate a lip-sync video by referring this.

Note

If you want to launch online video chats, you are suggested to generate videos using MuseV and apply necessary pre-processing such as face detection in advance. During online chatting, only UNet and the VAE decoder are involved, which makes MuseTalk real-time.

Acknowledgement

1. We thank open-source components like whisper, dwpose, face-alignment, face-parsing, S3FD.
2. MuseTalk has referred much to diffusers.
3. MuseTalk has been built on HDTF datasets.

Thanks for open-sourcing!

Limitations

• Resolution: Though MuseTalk uses a face region size of 256 x 256, which make it better than other open-source methods, it has not yet reached the theoretical resolution bound. We will continue to deal with this problem.
  If you need higher resolution, you could apply super resolution models such as GFPGAN in combination with MuseTalk.

• Identity preservation: Some details of the original face are not well preserved, such as mustache, lip shape and color.

• Jitter: There exists some jitter as the current pipeline adopts single-frame generation.
