How It Works

Understanding the technology behind real-time face swapping

1

Face Detection

Deep-Live-Cam uses advanced AI algorithms to detect faces in both the source image and target video or webcam feed. The system identifies facial landmarks, expressions, and key features with high precision.

  • Real-time face detection using InsightFace models
  • Accurate landmark detection for facial features
  • Support for multiple faces in a single frame
  • Robust detection even with varying lighting conditions
2

Face Analysis & Encoding

The detected faces are analyzed and encoded into high-dimensional feature vectors. This encoding captures the unique characteristics of each face, allowing the system to understand facial structure, expressions, and identity.

  • Deep neural network encoding
  • Feature extraction from source image
  • Facial landmark mapping
  • Expression and pose analysis
3

Face Swapping

The source face is seamlessly swapped onto the target face while preserving natural expressions, movements, and lighting. The AI ensures that the swapped face matches the target's pose, angle, and emotional expression.

  • Real-time face alignment
  • Expression preservation
  • Pose matching
  • Seamless blending techniques
4

Enhancement & Blending

The swapped face undergoes enhancement to ensure natural-looking results. Color matching, lighting adjustment, and edge blending create a seamless integration with the target video or image.

  • Color correction and matching
  • Lighting adjustment
  • Edge blending and smoothing
  • Quality enhancement using GFPGAN
5

Output Generation

The final processed frame is rendered and output. For videos, frames are processed sequentially and compiled into the final video file with preserved audio and frame rate.

  • Frame-by-frame processing
  • Video encoding with ffmpeg
  • Audio preservation
  • Quality optimization

Underlying Technology

InsightFace

Deep-Live-Cam utilizes InsightFace models for face recognition and analysis. This provides robust face detection and feature extraction capabilities.

ONNX Runtime

Optimized inference engine supporting multiple execution providers (CPU, CUDA, CoreML, DirectML, OpenVINO) for maximum performance.

GFPGAN

Face restoration and enhancement technology that improves the quality and natural appearance of swapped faces.

FFmpeg

Powerful video processing library for handling video encoding, decoding, and format conversion.

Processing Modes

Image/Video Mode

Process pre-recorded videos or images:

  1. Select your source face image
  2. Choose target video or image
  3. Click "Start" to begin processing
  4. Output is saved automatically

Webcam Mode

Real-time face swapping with your webcam:

  1. Select your source face image
  2. Click "Live" to start webcam feed
  3. Wait for preview (10-30 seconds)
  4. Use screen capture tools like OBS to stream
