Blackmagic ATEM 1 M/E Production Studio 4K is a live event multi camera production switcher with 10 individual Ultra HD inputs built into a 1RU chassis. Supporting NTSC/PAL/HD and Ultra HD video formats, the switcher connects to a wide range of cameras and sources, delivering a single program stream in SD, HD, or Ultra HD 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 provides 8 video outputs that are always active. It features two SDI and one HDMI Program output, both of which deliver SD/HD/Ultra HD, with one aux SD/HD/Ultra HD output that can deliver a clean program feed without any downstream effects. The switcher also features a down-converted HD output for monitoring on an SDI-equipped HD monitor. Multi view monitoring is 1080i only, over dedicated SDI or HDMI output, and multi view allows you to view the program, preview, and eight live sources at the same time. The switcher features built-in luma and chroma keyers for real time effects and composites in Ultra HD, with 10-bit processing. 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.
