33pt 3D LUT Processor

aja colorbox 3d lut example

Tetrahedral InterpolationThis primary 33pt. 3D LUT uses tetrahedral interpolation for the highest accuracy conversion. 3D LUTs provide full volumetric non-linear colour adjustment and a 33pt 3D LUT is a requirement for HDR workflows. Very useful for calibration purposes as the controls can respond to all possible calibration errors. Similarly, high end movie and television productions depend on 3D LUT processing for look generation, distribution, and management. When set to Dynamic, the 3D LUT is fully controllable through third party software like Pomfort Livegrade, Assimilate Live Looks, and QTAKE Video Assist.


aja colorbox 1d lut charts

four 1D LUTsFlexibility is key in production and post, with four 1D LUTs it is easy to manage your colour processing pipeline to get the best possible image. 1D LUTs are commonly used as “shaper LUTs” wrapping around the 3D LUT. The front shaper 1D LUT allows you to map perceptually significant values, typically the darker part of the colour space, to use more of the 3D LUT transform data set resulting in a more effective use of the 3D LUT to produce a better image. The backside shaper 1D LUT is usually the inverse of the front, mapping pixel values into the original dynamic range. 1D LUTs can also be effectively used as log-to-linear and linear-to-log transforms. In the AJA Color Pipeline, 1D LUTs can even be set up as RGB Colour Correctors for colour correcting a source before 3D LUT processing, this is a common workflow in live production applications.

3x3 Matrices

aja colorbox 3x3 matrices breakdown

perform different colour processing tasksColorBox’s two 3x3 Matrices provide the operator a means to perform different colour processing tasks outside of a LUT using their own 3x3 matrix files. 3x3 Matrices are commonly used for colour space conversion, for example between RGB and XYZ or YUV, BT. 709 and BT. 2020, or other colour spaces with different primaries. A 3x3 Matrix can be used to colour balance a signal if the white balance is off. They can also be used for look creation such as film emulation. In the AJA Color Pipeline, 3x3 Matrices can even be set up as Proc Amps for adjusting a signal’s Gain, Black level, Hue, and Saturation before 3D LUT processing, this is a common workflow in live production applications.

colour correction and image controlIn AJA Color Pipeline, the 1D LUTs can be configured as a RGB Colour Corrector and the 3x3 matrices as a Proc Amp. This allows for source colour correction and image control prior to or after performing a 3D LUT transform ensuring the best possible conversion. BBC HLG LUTs and NBCU LUTs pipelines also offer a RGB Colour Corrector and Proc Amp prior to 3D LUT processing.

Advanced ANC Metadata Management And Overlay

aja colorbox metadata interface

metadataColorBox offers several important features, from overlaying selected metadata and user data on the video for live use, capturing or embedding in the .tiff file for later use, or just passing ANC metadata to the next device. By storing the ANC data, one can quickly come back to and recall the exact camera settings, pipeline configuration, etc., that created an image. ColorBox also offers a customizable user text field that is great for overlaying any information on an image needing to be conveyed to an observer, such as camera or lens information, if the camera can’t provide it.

When setting up a shot, many factors need to be considered when framing it. The camera manufacturer, the sensor size, the lens, and the target aspect ratio all play a role. The ability to see frame lines on-set gives the production the best chance at capturing the shot composition correctly for the project from the get go. New with ColorBox is User Overlay, providing the ability to import and overlay custom images onto the output. Those images could be frame lines or any other image, such as a logo, imported as .png files to the Overlay library and recalled along with or without the already available overlay information.

User Text and User Overlay can also be stored on the captured image as part of the Overlay. Additional Overlay accessible data includes Input and Output VPID, Timecode presence, Closed Captioning presence, and Pipeline Configuration. Output HDMI infoframe status is also available in the UI.
