github huggingface space Technical report

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.

:new: Update: We are thrilled to announce that MusePose has been released. MusePose is an image-to-video generation framework for virtual human under control signal like pose. Together with MuseV and MuseTalk, we hope the community can join us and march towards the vision where a virtual human can be generated end2end with native ability of full body movement and interaction.

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] Release MuseTalk project and pretrained models.
• [04/16/2024] Release Gradio demo on HuggingFace Spaces (thanks to HF team for their community grant)
• [04/17/2024] : We release a pipeline that utilizes MuseTalk for real-time inference.
• [10/18/2024] :mega: We release the technical report. Our report details a superior model to the open-source L1 loss version. It includes GAN and perceptual losses for improved clarity, and sync loss for enhanced performance.

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.

Note that although we use a very similar architecture as Stable Diffusion, MuseTalk is distinct in that it is NOT a diffusion model. Instead, MuseTalk operates by inpainting in the latent space with a single step.

Cases

MuseV + MuseTalk make human photos alive！

• The character of the last two rows, Xinying Sun, is a supermodel KOL. You can follow her on douyin.

Video dubbing

• For video dubbing, we applied a self-developed tool which can identify the talking person.

Some interesting videos!

TODO:

• trained models and inference codes.
• Huggingface Gradio demo.
• codes for real-time inference.
• technical report.
• training codes.
• a better model (may take longer).

Getting Started

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

Third party integration

Thanks for the third-party integration, which makes installation and use more convenient for everyone. We also hope you note that we have not verified, maintained, or updated third-party. Please refer to this project for specific results.

ComfyUI

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

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:

│   └── pytorch_model.bin
├── dwpose
│   └── dw-ll_ucoco_384.pth

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, an image file or a directory of images.

You are recommended to input video with 25fps, the same fps used when training the model. If your video is far less than 25fps, you are recommended to apply frame interpolation or directly convert the video to 25fps using ffmpeg.

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. Frame interpolation is suggested to increase frame rate. Then, you can use MuseTalk to generate a lip-sync video by referring this.

:new: Real-time inference

Here, we provide the inference script. This script first applies necessary pre-processing such as face detection, face parsing and VAE encode in advance. During inference, only UNet and the VAE decoder are involved, which makes MuseTalk real-time.

python -m scripts.realtime_inference --inference_config configs/inference/realtime.yaml --batch_size 4

configs/inference/realtime.yaml is the path to the real-time inference configuration file, including preparation, video_path , bbox_shift and audio_clips.

1. Set preparation to True in realtime.yaml to prepare the materials for a new avatar. (If the bbox_shift has changed, you also need to re-prepare the materials.)
2. After that, the avatar will use an audio clip selected from audio_clips to generate video.

   Inferring using: data/audio/yongen.wav
   

3. While MuseTalk is inferring, sub-threads can simultaneously stream the results to the users. The generation process can achieve 30fps+ on an NVIDIA Tesla V100.
4. Set preparation to False and run this script if you want to genrate more videos using the same avatar.

Note for Real-time inference

1. If you want to generate multiple videos using the same avatar/video, you can also use this script to SIGNIFICANTLY expedite the generation process.
2. In the previous script, the generation time is also limited by I/O (e.g. saving images). If you just want to test the generation speed without saving the images, you can run

python -m scripts.realtime_inference --inference_config configs/inference/realtime.yaml --skip_save_images

Acknowledgement

1. We thank open-source components like whisper, dwpose, face-alignment, face-parsing, S3FD.
2. MuseTalk has referred much to diffusers and isaacOnline/whisper.
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.
