The Blackmagic ATEM Production Studio 4K Live Switcher is a live event multicamera production switcher with eight individual Ultra HD inputs built into a 1 RU chassis. Supporting NTSC/PAL/HD and Ultra HD video formats via four Single-Link 6G-SDI and four 4K HDMI inputs, the switcher connects to a wide range of cameras and sources, delivering a single program stream in SD, HD, or UHD 4K video. All this is done live and in real time with no rendering required. The switcher features a reference video input for synchronizing the switcher to other equipment using tri-level or Blackburst Sync. Each input also features its own frame synchronizer, which allows you to use cameras that do not feature Genlock as well as input video from computer sources. The switcher can handle inputs from all inputs at the same time.

The switcher provides six video outputs that are always active. Featuring one SDI and one HDMI Program output, both of which deliver SD/HD/UHD 4K, with one Aux SD/HD/UHD 4K output that can deliver a clean program feed without any downstream effects, as primary outputs. The switcher also features an HD-only program output signal for monitoring on an SDI-equipped HD monitor. Multiview monitoring is also HD only over dedicated SDI or HDMI output, and multiview allows you to view the program, preview, six active inputs, and two graphic channels (media players) on one screen at the same time. The switcher features one upstream and two downstream keyers for real-time effects and composites in Ultra HD, with 10-bit processing. The two downstream keyers allow you to use two graphics/logos/titles/lower thirds from up to twenty stored graphics in a wide variety of formats.
