AJA ColorBox In-line HDR/SDR Algorithmic and LUT Color Transforms
Introduction
ColorBox from AJA is a compact, high-performance converter for color managed workflows designed to specifically meet the conversion needs of broadcast, live events, and on-set applications. Supporting Standard Dynamic Range (SDR), High Dynamic Range (HDR), and Wide Color Gamut (WCG) signals, it utilizes 12G-SDI and HDMI 2.0 for single wire 4K/UltraHD HDR up to 4:2:2 10-bit 60p or 4:4:4 12-bit 30p with a unique color processing pipeline.
Built around the 33-point 3D LUT processor with tetrahedral interpolation, AJA Color Pipeline provides additional 4x 1D LUTs and 2x 3×3 matrices that are each individually configurable even as Proc Amps or RGB Color Correctors. Easily manage color processing options via the web user interface which can be accessed directly from a wired Ethernet connection or through a wireless connection via a third party WiFi USB adapter.
ColorBox includes processing pipeline modes from Colorfront and NBCU LUTs, as well as a powerful AJA Color Pipeline. ColorBox also expands its capabilities by offering licensable upgrade options for advanced color managed workflows, including BBC HLG LUTs and the all new ORION-CONVERT engine. ORION-CONVERT’s unique real-time floating point math approach to color transforms produces higher precision results to get “access to the colors between the colors.” This enables pixel perfect color transforms and round tripping where maintaining colors is paramount.
ColorBox also offers a sophisticated test pattern generator and frame store, bringing useful tools to your workflow, including the ability to capture up to a 4K image as a 16-bit .tiff file for the highest quality reference stills. ColorBox can even overlay information onto the image, including helpful user definable text fields. These images can be saved locally on ColorBox or onto a third party connected PC running an application like Pomfort’s Livegrade Pro/Studio and Assimilate Live Looks.
