Mac camera extension
Publish the connected camera through a native macOS camera extension for compatible video apps.
Flexible output
Choose 1920×1080, 1280×720, 960×540, or 640×360 output and common output frame rates.
How to use a Canon DSLR as a Mac webcam
- Connect a supported Canon camera to your Mac with a USB data cable.
- Open ViewportCam, start live view, and install and approve the webcam extension.
- Choose “ViewportCam - Connected Camera” in your call, streaming, or recording app.
The 1920×1080 option is an upscaled output from the camera’s USB live-view feed, not a native 1080p source. Actual source motion depends on the camera’s USB live-view frame rate.
Not only a webcam
Before you join a call—or instead of joining one—use ViewportCam for a full-screen preview, supported camera controls, photo capture, in-camera movie recording, and camera-file downloads.
