The ATEM 1 M/E Constellation UHD 4K Live Production Switcher adds UHD 4K capabilities and 12G-SDI ports to the familiar switcher construction of its predecessor. Designed for powerful live event UHD 4K switching, the unit features 10 individual 12G-SDI inputs that support 12G/3G/HD-SDI signals and deliver them to six 12G-SDI outputs or webcam USB-C output. In addition, the switcher has a multiview output with up to 16 routable windows that can display inputs, keyed video, graphics, and stills from the media pool, as well as the program output. Each input connects to a built-in Fairlight audio mixer supporting up to 28 channels of audio.

The switcher features a reference video input, and each input features a frame synchronizer, frame rate converter, and format converter. This allows you to mix and match cameras, formats, cameras that do not feature genlock, and video input from computer sources. Upstream and downstream keyers and effects are supported. All this is done live and in real time with no rendering required. You can control the switcher using the integrated front panel, optional Blackmagic ATEM panels, or via the downloadable control software.
