NOTE: RGB Color Correctors are also available with the BBC HLG LUTs and NBCU LUTs
pipelines.
3x3 Matrix Nodes
ColorBox’s two 3x3 Matrices provide the operator a means to perform different
color processing tasks outside of a LUT using their own 3x3 matrix files. 3x3
Matrices are commonly used for colorspace conversion, for example between
RGB and XYZ or YUV, BT. 709 and BT. 2020, or other color spaces with different
primaries. A 3x3 Matrix can be used to color balance a signal if the white balance
is off. They can also be used for look creation such as film emulation.
Available options are:
• Matrix
• Dynamic
• Proc Amp
• SMPTE Narrow to SMPTE FULL
• SMPTE FULL to SMPTE Narrow
Proc Amp
In the AJA Color Pipeline, 3x3 Matrices can 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.
