LUT Screen
The LUT screen controls allow you to create a custom color look up table (LUT) on the output, for
matching a production “look” on a specific display.
Users can also specify their own custom LUTs by creating a LUT file and uploading it to an AJA
Video Device using the LUT (lookup table) screen in the Control Panel.
Custom LUT Controls
The LUT Transfer Function screen displays an approximate representation of the effect of the current
LUT settings. When the controls are activated by selecting a User LUT Type, Red, Blue, and Green
curves show the transfer functions of each color.
n
The displayed curves are approximate,. Curves for some extreme settings may diverge significantly
from the actual transfer functions.
LUT Type
Selects the type of LUT. Choose from
•
Auto - LUT will be automatically selected. This setting intelligently applies the type of LUT
required in the majority of use cases. For example, if the Frame Buffer is set to SD 608 and the
Output set to HD 709, then an industry standard curve for changing 608 to 709 color space is
applied.
•
Linear - A linear 1:1 LUT is applied, resulting in no color change (every value for source is
mapped to the same value for output).
