You get amazing quality, and the DVE supports position, resize, and scale, all in real time. The ATEM Constellation features two independent DVEs that let you reposition graphics and create picture-in-picture compositions. To eliminate errors, ATEM Constellation HD features a preview transition feature so you can set up your transitions before you switch it on air. The DVE can even be used to create graphic wipe transitions. The ATEM Constellation switcher includes a powerful digital video effects processor for DVE transitions, which can be used to squeeze the current picture offscreen, revealing a new video under it. All transitions can be customized in the system control menus with adjustments for border color, border width, position, direction, and a lot more.

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 156 channels of audio.

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. 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. Owerful live event HD switching, supporting up to 40 individual 3G-/HD-SDI inputs built into a 2 RU chassis, is at hand with the Blackmagic Design ATEM 4 M/E Constellation HD Live Production Switcher.
