The ATEM 2 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 20 individual 12G-SDI inputs that support 12G/3G/HD-SDI signals and deliver them to 12 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 ATEM chroma keyer features a color picker to sample background colors for automatic generation of the key parameters. Use the precise controls to adjust edge and flare, and there is even a foreground color corrector to match the look to the background layer for seamless compositions. The keyer can be used for pattern and DVE keying applications. You get eight Advanced Keyers with the 2 M/E model.
- There are four upstream keyers per M/E row for virtual set building. You can use a keyer per camera to create cohesive compositions over a custom background in a 4-camera virtual set. You can use external image processors or build a fixed camera set by loading pre-rendered still image backgrounds from the media players and media pool. Set up macros to change cameras and load the correct background into the players.
