The ATEM Constellation HD includes a wide range of broadcast-quality native transitions such as mix, dip, wipe, and more.

You can control the switcher using the integrated front panel, optional Blackmagic ATEM panels, or via the downloadable control software. All this is done live and in real time with no rendering required. Upstream and downstream keyers and effects are supported. This allows you to mix and match cameras, formats, cameras that do not feature genlock, and video input from computer sources. The switcher features a reference video input, and each input features a frame synchronizer, frame rate converter, and format converter. Each input connects to a built-in Fairlight audio mixer supporting up to 28 channels of audio. 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.

Supporting 3G-SDI and HD-SDI signals, the switcher connects to a wide range of cameras and sources, delivering program output via six 3G-SDI BNC outputs or a webcam output via USB Type-C.
