How do I use a video camera as a webcam?
assistant
To use a video camera as a webcam you will need to connect it to your computer using its video output connection, usually a USB port or HDMI port. Once you have the connection established, open your computer's System Preferences, select the camera option and select your video camera as the camera source. Depending on the type of camera, you may also need to download and install a driver before the camera can be used as a webcam.
