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

The NVIDIA Broadcast virtual camera becomes available system-wide.
Select in Meeting App
Choose "NVIDIA Broadcast" as your camera in Zoom, Teams, or any other app.
OBS as Universal Bridge
- Capture any avatar software as an OBS source (window capture or game capture)
- Apply chroma key to remove green background
- Composite avatar with custom backgrounds, overlays, or lower thirds
- Output via OBS Virtual Camera to any video call app
- Most flexible option: works with any avatar software
Recommendation: For the simplest setup, use NVIDIA Broadcast (if you have an RTX GPU). For maximum flexibility with any avatar software, use the OBS Virtual Camera approach.
