Facial Motion Capture

Facial motion capture (face mocap) tracks the movement of a performer's face in real time using specialized cameras, depth sensors, or marker-based systems. The captured data is typically mapped onto a digital character or used to drive facial animations.

While traditional motion capture requires expensive equipment and controlled studio environments, AI-based approaches can extract facial motion data from standard video footage. AI lip sync technology has emerged as a lightweight alternative for mouth-specific animation, generating accurate lip movements directly from audio without needing any motion capture hardware.

Facial Motion Capture relates to several other concepts in the AI lip sync pipeline: Face Landmark Detection , and Expression Transfer .
