SIGGRAPH Asia 2022 Conference Track

We present VideoReTalking, a new system to edit the faces of a real-world talking head video according to input audio, producing a high-quality and lip-syncing output video even with a different emotion. Our system disentangles this objective into three sequential tasks:

(1) face video generation with a canonical expression
(2) audio-driven lip-sync and
(3) face enhancement for improving photo-realism.

Given a talking-head video, we first modify the expression of each frame according to the same expression template using the expression editing network, resulting in a video with the canonical expression. This video, together with the given audio, is then fed into the lip-sync network to generate a lip-syncing video. Finally, we improve the photo-realism of the synthesized faces through an identity-aware face enhancement network and post-processing. We use learning-based approaches for all three steps and all our modules can be tackled in a sequential pipeline without any user intervention.

Quick Inference

Pretrained Models

Please download our pre-trained models and put them in ./checkpoints.


python3 \
  --face examples/face/1.mp4 \
  --audio examples/audio/1.wav \
  --outfile results/1_1.mp4

This script includes data preprocessing steps. You can test any talking face videos without manual alignment. But it is worth noting that DNet cannot handle extreme poses.

You can also control the expression by adding the following parameters:

--exp_img: Pre-defined expression template. The default is "neutral". You can choose "smile" or an image path.

--up_face: You can choose "surprise" or "angry" to modify the expression of upper face with GANimation.
