Frequently Asked Questions

What is Live Portrait?

Live Portrait is a video-driven portrait animation framework that focuses on better generalization, controllability, and efficiency for practical usage. It's designed to synthesize lifelike videos from a single source image.

What are the main features of Live Portrait?

Live Portrait's main features include generating realistic videos using a single source image as an appearance reference, with motion (facial expressions and head pose) derived from driving videos, audio, text, or generation. It supports self-reenactment, cross-reenactment, eye and lip retargeting control, and various styles (realistic, oil painting, sculpture, 3D rendering).

Who developed Live Portrait?

Live Portrait was developed by researchers from Kuaishou Technology, University of Science and Technology of China, and Fudan University.

What core technologies does Live Portrait use?

Live Portrait explores and extends the potential of the implicit-keypoint-based framework, balancing computational efficiency and controllability. It uses a mixed image-video training strategy, upgraded network architecture, and improved motion transformation and optimization objectives. It also incorporates stitching and retargeting modules using small MLPs for enhanced control.

What are the application scenarios for Live Portrait?

Live Portrait can be used for various portrait animation scenarios, including self-reenactment, cross-reenactment, portrait animation from still images, portrait video editing, eye and lip retargeting control, and animation across different styles. It can also be fine-tuned for animal animation (cats, dogs, pandas).

What is the performance of Live Portrait?

Live Portrait achieves a generation speed of 12.8ms on an RTX 4090 GPU using PyTorch. The project used about 69 million high-quality frames for training to enhance generation quality and generalization ability.

How can I get more information about the Live Portrait open-source project?

You can find the inference code and models at Live Portrait GitHub Repository. More detailed information and experimental results are available on the project's GitHub page.
