Live Portrait: Animate Static Photos with AI

What is Live Portrait? Live Portrait is an AI-powered tool that transforms static photos into lifelike animations. It allows users to create dynamic and expressive videos from a single portrait image, bringing still photos to life with realistic facial expressions, head movements, and lip synchronization.

Key Features

• Multi-Style Portrait Animation: Animate still images across various styles and sizes using stitching technology.
• Portrait Video Editing with Stitching: Offers dynamic video-to-video face animation and editing capabilities.
• Precise Eye Animation Control: Dynamically adjusts eye openness using scalar inputs for nuanced expression control.
• Accurate Lip Movement Control: Fine-tunes lip positions with scalar-based inputs, allowing for precise speech and expression animation.
• Advanced Self-reenactment: Generates high-quality animations from a single source frame, recreating dynamic video sequences.
• Powerful Cross-reenactment: Accurately transfers motion between different portraits, handling diverse scenarios from large pose changes to subtle expressions and multi-person inputs.

How Live Portrait Works

Live Portrait leverages cutting-edge AI technology to animate static photos:

1. Feature Extraction: Built upon the vid2vid model and trained on a vast dataset of high-quality images and videos, it extracts key features from the source image and driving video.
2. Implicit Keypoint Animation: An innovative implicit keypoint framework maps motion from the driving video onto the portrait, ensuring efficient and controllable animation.
3. High Efficiency Video Synthesis: An optimized decoder rapidly generates each frame, creating smooth animations efficiently while maintaining the source image's identity.
4. Precision Control and Enhancement: Stitching and retargeting modules refine the output, allowing for fine-grained control over facial expressions and movements with minimal computational overhead.

How to Use Live Portrait

Transform your static photo into a lifelike animation in three simple steps:

1. Upload Portrait Image: Upload a portrait photo with a clear face. Live Portrait will extract facial features from this image for animation purposes.
2. Select or Upload Driving Video: Choose or upload a driving video showing facial movements. This video will guide the facial motion generation for your portrait image.
3. Generate Animation: Click 'Animate', adjust configuration parameters if desired or keep the defaults, then click to generate and wait for the process to complete.
