Product Overview
Facebetter is a real-time beauty effects engine designed for developers. It delivers high-quality AI-powered beauty processing for both images and live video streams. Built on a GPU rendering pipeline, the engine achieves low latency, minimal CPU usage, and high frame rates, and integrates seamlessly into Android, iOS, macOS, Web, and other major platforms.
Core Features
Skin Beauty
Fine-grained skin enhancement with four independently adjustable parameters — smoothing, whitening, rosy tone, and sharpening. Each parameter supports an intensity range of 0–100 for precise control over the final look.
Face Reshaping
Comprehensive adjustments spanning facial contour and feature proportions:
- Face shape: face slimming, V-face, narrow face, short face
- Contour: cheekbone slimming, jaw slimming, chin slimming
- Features: nose bridge slimming, eye enlarging, eye distance adjustment
A single frame supports up to 5 people being reshaped simultaneously.
Makeup
Realistic layered makeup effects including lipstick (color and opacity adjustable) and blush (multiple preset shades). Multiple makeup items can be applied at the same time.
A single frame supports up to 5 people with makeup applied simultaneously.
Filters & Styles
20+ real-time style filters based on LUT (Look-Up Table) color grading, covering portrait, food, landscape, modern, and other themes. Intensity adjustment and custom LUT extension are supported.
Virtual Background
Powered by real-time portrait segmentation:
- Background blur: keeps the foreground subject sharp while applying Gaussian blur to the background
- Background replacement: swaps the background with any image asset
Sticker Effects
2D sticker effects including:
- Screen stickers: overlaid at a fixed position on the frame
- Face-tracking stickers: anchored to face keypoints and dynamically follow head movement
Sticker resources are distributed as .fbpack packages with support for hot-loading and dynamic switching.
Advanced Features
- Face keypoint callbacks: returns 106 facial landmark coordinates per frame for custom effect development and business logic
- Green screen keying (Chroma Key): precise removal of green backgrounds, suitable for live streaming and video compositing
