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.

🔥 Updates

We're excited to unveil MuseTalk 1.5. This version (1) integrates training with perceptual loss, GAN loss, and sync loss, significantly boosting its overall performance. (2) We've implemented a two-stage training strategy and a spatio-temporal data sampling approach to strike a balance between visual quality and lip-sync accuracy. Learn more details here

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 and private dataset.

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.

:rocket: Blackwell GPU Optimizations (RTX 5090)

MuseTalk now includes automatic optimizations for NVIDIA Blackwell GPUs (RTX 50 series) that provide significant speedups with zero quality degradation.

Performance Benchmarks (RTX 5090)

Quality Comparison (FP16 vs FP32)

Optimizations Applied

The following optimizations are automatically enabled on Blackwell GPUs:

How to Use

Optimizations are enabled by default when running on RTX 5090:

# Automatic - just use the engine normally
from server.fast_engine import initialize_engine
engine = initialize_engine()  # Blackwell optimizations auto-applied

To disable (for debugging or comparison):

engine = FastMuseTalkEngine()
engine.load_models(use_blackwell_optimizations=False)

Run Benchmark

To verify performance on your hardware:

python tests/benchmark_mxfp4.py

Requirements

• GPU: NVIDIA RTX 5090 (Blackwell, compute capability 12.0)
• CUDA: 12.8+
• PyTorch: 2.9.0+

For detailed documentation, see docs/MXFP4_OPTIMIZATION.md.

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:

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

Download weights

You can download weights manually as follows:

1. Download our trained weights.

# !pip install -U "huggingface_hub[cli]" 
export HF_ENDPOINT=https://hf-mirror.com 
huggingface-cli download TMElyralab/MuseTalk --local-dir models/

1. 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:

Quickstart

Inference

We provide inference scripts for both versions of MuseTalk:

MuseTalk 1.5 (Recommended)

sh inference.sh v1.5

This inference script supports both MuseTalk 1.5 and 1.0 models:

• For MuseTalk 1.5: Use the command above with the V1.5 model path
• For MuseTalk 1.0: Use the same script but point to the V1.0 model path

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.

MuseTalk 1.0

sh inference.sh v1.0

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(For 1.0)

: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.

</details>

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.

Real-time inference

<details close> 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

</details>

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.
