The ATEM 4 M/E Constellation 4K Switcher from Blackmagic Design features 40 12G-SDI inputs and 24 12G-SDI outputs, and it connects to a wide range of cameras and sources, delivering video at resolutions of up to 10-bit UHD 4K60 via the 12G-SDI program outputs or 1080p and 720p webcam outputs via USB-C. The switcher features 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 also boasts a reference video input, and each input features a frame synchronizer, frame rate converter, and format converter, allowing you to mix and match cameras that do not have genlock capabilities. Upstream and downstream keyers and effects are supported in real time. The switcher can be controlled using the integrated front panel, optional Blackmagic ATEM panels, or via the downloadable control software.
