Even if you have a camera that can shoot 4K video, the USB adapter may only support 1080p output. The quality of the video that your computer receives is limited by the device. The beauty of this setup is that you can generally use any HDMI source as the input, from a camera to a game console to another computer, and the output can be used however you’d like, from video conferencing to livestreaming or recording. You’ll need a device that converts your camera’s HDMI feed to a USB output that your computer will think is a connected webcam. And while cameras have USB ports, they generally do not send a clean video signal through them. If your computer has an HDMI port, it is likely itself an output port. Most computers cannot natively read the video coming from a camera’s HDMI output.
With major camera manufacturers like Canon, Nikon, Sony, Fujifilm, Panasonic, Olympus, and GoPro recently building a webcam option into their software, the odds are now pretty good that you can modify your current camera to use as a webcam, for free. Fortunately, with the right tools, using your DSLR or mirrorless camera as a webcam is a straightforward procedure. To accomplish this, you’ll need some specific hardware and/or software to get your camera and computer to play nice.
