Model overview

sadtalker is an AI model developed by researchers at Tencent AI Lab and Xi'an Jiaotong University that enables stylized audio-driven single image talking face animation. It extends the popular video-retalking model, which focuses on audio-based lip synchronization for talking head video editing. sadtalker takes this a step further by generating a 3D talking head animation from a single portrait image and an audio clip.

Model inputs and outputs

sadtalker takes two main inputs: a source image (which can be a still image or a short video) and an audio clip. The model then generates a talking head video that animates the person in the source image to match the audio. This can be used to create expressive, stylized talking head videos from just a single photo.

Inputs

  • Source Image: The portrait image or short video that will be animated
  • Driven Audio: The audio clip that will drive the facial animation

Outputs

  • Talking Head Video: An animated video of the person in the source image speaking in sync with the driven audio

Capabilities

sadtalker is capable of generating realistic 3D facial animations from a single portrait image and an audio clip. The animations capture natural head pose, eye blinks, and lip sync, resulting in a stylized talking head video. The model can handle a variety of facial expressions and is able to preserve the identity of the person in the source image.

What can I use it for?

sadtalker can be used to create custom talking head videos for a variety of applications, such as:

  • Generating animated content for games, films, or virtual avatars
  • Creating personalized videos for marketing, education, or entertainment
  • Dubbing or re-voicing existing videos with new audio
  • Animating portraits or headshots to add movement and expression

The model's ability to work from a single image input makes it particularly useful for quickly creating talking head content without the need for complex 3D modeling or animation workflows.

Things to try

Some interesting things to experiment with using sadtalker include:

  • Trying different source images, from portraits to more stylized or cartoon-like illustrations, to see how the model handles various artistic styles
  • Combining sadtalker with other AI models like stable-diffusion to generate entirely new talking head characters
  • Exploring the model's capabilities with different types of audio, such as singing, accents, or emotional speech
  • Integrating sadtalker into larger video or animation pipelines to streamline content creation

The versatility and ease of use of sadtalker make it a powerful tool for anyone looking to create expressive, personalized talking head videos.

video-retalking is a system developed by researchers at Tencent AI Lab and Xidian University that enables audio-based lip synchronization and expression editing for talking head videos. It builds on prior work like Wav2Lip, PIRenderer, and GFP-GAN to create a pipeline for generating high-quality, lip-synced videos from talking head footage and audio. Unlike models like voicecraft, which focus on speech editing, or tokenflow, which aims for consistent video editing, video-retalking is specifically designed for synchronizing lip movements with audio. Model inputs and outputs video-retalking takes two main inputs: a talking head video and an audio file. The model then generates a new video with the facial expressions and lip movements synchronized to the provided audio. This allows users to edit the appearance and emotion of a talking head video while preserving the original audio. Inputs Face**: Input video file of a talking-head. Input Audio**: Input audio file to synchronize with the video. Outputs Output**: The generated video with synchronized lip movements and expressions. Capabilities video-retalking can generate high-quality, lip-synced videos even in the wild, meaning it can handle real-world footage without the need for extensive pre-processing or manual alignment. The model is capable of disentangling the task into three key steps: generating a canonical face expression, synchronizing the lip movements to the audio, and enhancing the photo-realism of the final output. What can I use it for? video-retalking can be a powerful tool for content creators, video editors, and anyone looking to edit or enhance talking head videos. Its ability to preserve the original audio while modifying the visual elements opens up possibilities for a wide range of applications, such as: Dubbing or re-voicing videos in different languages Adjusting the emotion or expression of a speaker Repairing or improving the lip sync in existing footage Creating animated avatars or virtual presenters Things to try One interesting aspect of video-retalking is its ability to control the expression of the upper face using pre-defined templates like "smile" or "surprise". This allows for more nuanced expression editing beyond just lip sync. Additionally, the model's sequential pipeline means each step can be examined and potentially fine-tuned for specific use cases.
