The 4K Real-Time Chroma Keyer with 10-Bit, 4:4:4 Video Processing from Datavideo provides you with high-quality, real-time chroma keying using 10-bit processing and 4:4:4 color sampling for clean edges with limited artifacts. The keyer supports video up to UHD 4K, and it is designed to allow you to choose from green or blue as the background to key your foreground subject. The keyer does all the processing in real time, requiring your computer only for interface control and adjustment using the downloadable DVK-400 software app for Windows.

This is a live keyer, which allows you to composite a foreground over a live video background, supporting both SDI and HDMI inputs for foreground and background as well as SDI and HDMI outputs for preview and program output. A separate HDMI input allows for an external matte as well as text, graphics, and video overlays. The keyer's sophisticated algorithms help preserve the transparency in smoke as well as providing clean keys with blonde hair, water-filled bottles, or glass objects. The DVK-400 is 1 RU tall and has built-in rackmount ears; it also has removable feet for desktop applications.
