Blackmagic Design ATEM 4 M/E Constellation HD Live Production Switcher. Supporting 3G-SDI and HD-SDI signals, the switcher connects to a wide range of cameras and sources, delivering program output via 24 3G-SDI BNC outputs or a webcam output via USB Type-C. In addition, the switcher has four multiview outputs 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 156 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.
