Datavideo DVK-400 4K Chromakey Processor
The DVK-400 is a dedicated 4K chromakey processor for productions that need a clean green or blue-screen composite without tying up a full switcher's keying channel. It works in 4:4:4 10-bit internally and handles resolutions up to 2160p60, with an auto chromakey mode that speeds up dialing in a clean edge on the talent.
Foreground video comes in over 12G/6G/3G-SDI or HDMI 2.0, with a separate HDMI 2.0 input for the background plate and an HDMI 1.4 AUX input for a third source, so foreground, background, and graphics stay on independent feeds. The composited program goes out on two SDI and one HDMI 2.0 output, and dedicated SDI and HDMI preview outputs let an operator check the key before it goes to air.
