TL;DR: single portrait image 🙎‍♂️ + audio 🎤 = talking head video 🎞.

Highlights

The license has been updated to Apache 2.0, and we've removed the non-commercial restriction
SadTalker has now officially been integrated into Discord, where you can use it for free by sending files. You can also generate high-quailty videos from text prompts. Join:
We've published a stable-diffusion-webui extension. Check out more details here. Demo Video
Full image mode is now available! More details...

still+enhancer in v0.0.1	still + enhancer in v0.0.2	input image @bagbag1815

Several new modes (Still, reference, and resize modes) are now available!
We're happy to see more community demos on bilibili, YouTube and X (#sadtalker).

Changelog

The previous changelog can be found here.

[2023.06.12]: Added more new features in WebUI extension, see the discussion here.
[2023.06.05]: Released a new 512x512px (beta) face model. Fixed some bugs and improve the performance.
[2023.04.15]: Added a WebUI Colab notebook by @camenduru:
[2023.04.12]: Added a more detailed WebUI installation document and fixed a problem when reinstalling.
[2023.04.12]: Fixed the WebUI safe issues becasue of 3rd-party packages, and optimized the output path in sd-webui-extension.
[2023.04.08]: In v0.0.2, we added a logo watermark to the generated video to prevent abuse. This watermark has since been removed in a later release.
[2023.04.08]: In v0.0.2, we added features for full image animation and a link to download checkpoints from Baidu. We also optimized the enhancer logic.

To-Do

We're tracking new updates in issue #280.

Troubleshooting

If you have any problems, please read our FAQs before opening an issue.

1. Installation.

Community tutorials: 中文Windows教程 (Chinese Windows tutorial) | 日本語コース (Japanese tutorial).

Linux/Unix

Install Anaconda, Python and git.
Creating the env and install the requirements.

git clone https://github.com/OpenTalker/SadTalker.git

cd SadTalker 

conda create -n sadtalker python=3.8

conda activate sadtalker

pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113

conda install ffmpeg

pip install -r requirements.txt

### Coqui TTS is optional for gradio demo. 
### pip install TTS

Windows

A video tutorial in chinese is available here. You can also follow the following instructions:

Install Python 3.8 and check "Add Python to PATH".
Install git manually or using Scoop: scoop install git.
Install ffmpeg, following this tutorial or using scoop: scoop install ffmpeg.
Download the SadTalker repository by running git clone https://github.com/Winfredy/SadTalker.git.
Download the checkpoints and gfpgan models in the downloads section.
Run start.bat from Windows Explorer as normal, non-administrator, user, and a Gradio-powered WebUI demo will be started.

macOS

A tutorial on installing SadTalker on macOS can be found here.

Docker, WSL, etc

Please check out additional tutorials here.

2. Download Models

You can run the following script on Linux/macOS to automatically download all the models:

bash scripts/download_models.sh

We also provide an offline patch (gfpgan/), so no model will be downloaded when generating.

Pre-Trained Models

3. Quick Start

Please read our document on best practices and configuration tips

WebUI Demos

Online Demo: HuggingFace | SDWebUI-Colab | Colab

Local WebUI extension: Please refer to WebUI docs.

Local gradio demo (recommanded): A Gradio instance similar to our Hugging Face demo can be run locally:

## you need manually install TTS(https://github.com/coqui-ai/TTS) via `pip install tts` in advanced.
python app_sadtalker.py

You can also start it more easily:

windows: just double click webui.bat, the requirements will be installed automatically.
Linux/Mac OS: run bash webui.sh to start the webui.

CLI usage

Animating a portrait image from default config:

python inference.py --driven_audio <audio.wav> \
                    --source_image <video.mp4 or picture.png> \
                    --enhancer gfpgan

The results will be saved in results/$SOME_TIMESTAMP/*.mp4.

Full body/image Generation:

Using --still to generate a natural full body video. You can add enhancer to improve the quality of the generated video.

python inference.py --driven_audio <audio.wav> \
                    --source_image <video.mp4 or picture.png> \
                    --result_dir <a file to store results> \
                    --still \
                    --preprocess full \
                    --enhancer gfpgan
