Elgato says the device supports Discord, OBS Studio, and Skype, as well as cameras from Canon, GoPro, Nikon, Sony, and Panasonic. The Cam Link 4K takes HDMI input from a camera and translates it into video at up to 4K at 30 fps, or 1080p at 60 fps. For aspiring creators on Twitch and YouTube, this product promises to significantly upgrade live-streaming video quality without requiring you purchase an expensive webcam. It’s a 4K version of its existing Cam Link dongle. The device, an upgraded USB dongle called Cam Link 4K, acts as an intermediary between Elgato’s software on your laptop or desktop and the camera itself. Game capture and streaming hardware company Elgato announced a new gadget today that can turn any existing DSLR camera, action cam, or standard video camcorder into a 4K webcam.
