What is the Viral Face Lock Effect?
The face lock effect (also called the lock-on effect or face tracking stabilization) is an editing technique where the camera is mathematically anchored to a subject's face or nose. As the person dances, runs, or moves around, their face remains dead-center on screen while the background whips and rotates dynamically around them.
Made famous by TikTok dance trends, hip-hop music videos, and sports creators, this effect typically required either expensive desktop compositing software like Adobe After Effects or ad-riddled mobile apps. CenterFace AI brings full professional face locking directly to your browser for free.
