AJA - ColorBox

News & Events at DigiBox


ColorBox from AJA is a compact, high-performance converter for colour 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 Colour Gamut (WCG) signals, it utilises 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 colour processing pipeline. 

Built around the 33-point 3D LUT processor with tetrahedral interpolation, AJA Colour Pipeline provides additional 4x 1D LUTs and 2x 3x3 matrices that are each individually configurable even as Proc Amps or RGB Colour Correctors. Easily manage colour 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 Colour Pipeline. ColorBox also expands its capabilities by offering licensable upgrade options for advanced colour 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 colour 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.

Integration Across Broad Applications

ColorBox offers key applications for modern workflows, including:

  • 4K/UltraHD SDR and HDR pipelines for live television and concert production.  OB trucks and other live event infrastructure can easily use ColorBox to convert SDR signals to HDR and HDR to other delivery formats.  The licensable ORION-CONVERT and BBC HLG LUTs options as well as the free built-in Colorfront transforms and NBCU LUTs provide all the necessary tools to manage HDR workflows.  For hardware based control, SKAARHOJ and CyanView have integrated native control of ColorBox into their control panels.
  • On set look management and color grading for DITs or anyone in charge of ensuring that the content captured on set will meet the needs of the Cinematographer, Director of Photography, colorist, costume and lighting designers, and editors on the production. A DIT can easily manage workflows to load multiple looks, make adjustments as needed and save reference images (up to 4K) for dailies, postproduction, and later use. Pomfort’s Livegrade Pro and Studio and Assimilate Live Looks and Live Assist integrate easily, offering native control of ColorBox in real time.  The unique full frame processing capability of ColorBox eliminates partial frame LUT processing.
  • Monitor Calibration. Wherever the highest quality display calibration is required for a production studio, rental house, production or post production facility, ColorBox can help. ColorBox features an extensive API that allows 3rd parties to control the ColorBox Frame Store and its ability to output 12-bit RGB test patches for high quality monitor calibration applications.

Compact Form Factor

ColorBox is just 4in. x 7.5in., requiring a small footprint on your desktop or you can rack mount up to four ColorBox devices in just 1RU for easy addition to both production and post installations, in DIT carts, fly away kits, and equipment racks.  It is also lightweight at just 1 lb. making it perfect for DIT and mobile applications.


ColorBox comes with a range of Pipelines to choose from. Select any particular Pipeline for your production needs. Some Pipelines are designed specifically for live broadcast or live event needs. Others, like the AJA Colour Pipeline, offer great flexibility for more control over each step of a transform for any application. Pipelines like BBC HLG LUTs or ORION-CONVERT will display a watermark over the image until a license is applied offering you the ability to evaluate the colour science prior to purchasing the optional license. ColorBox offers unique image processing capabilities with an unrivaled array of options for a device of its type with full 12-bit 4:4:4 up to 4K 30p and 10-bit 4:2:2 up to 4K 60p.  Full bypass nodes are also offered for both 12G-SDI and HDMI 2.0 out, for quick comparisons.

These are the five Pipelines available:

  • AJA Colour
  • Colorfront 
  • ORION-CONVERT (requires License to remove watermark)
  • BBC HLG LUTs (requires License to remove watermark)
