ColorBox from AJA is a high performance color management device specifically designed to meet the color conversion and color correction needs of broadcast, live events, and on-set applications. Supporting HDR, SDR, and Wide Color Gamut (WCG) signals, it utilizes 12G-SDI for single wire 4K/UltraHD up to 4:2:2 10-bit 60p or 4:4:4 12-bit 30p, with a unique color processing pipeline, and down-conversion. The ColorBox’s ultra-low latency, less than ½ of a video line, makes it ideal for color managed workflows for live productions.
