Camera Replacement

Virtual camera tools create a universal bridge between AI avatar software and any video call platform, giving you consistent avatar access across Zoom, Teams, Meet, and every other app.

How Virtual Cameras Work

A virtual camera is a software driver that appears as a camera device to your operating system:

1. Avatar software renders your animated character
2. The rendered output is sent to a virtual camera driver
3. Any application that uses a camera (Zoom, Teams, Meet, etc.) can select the virtual camera
4. The app receives the avatar video as if it were a real webcam feed
