LUT Screen
The LUT screen allows you to create a custom color look up table (LUT) on the
Io IP output, for matching a production "look" on a specific display. These custom
LUTs can also be exported as .cube files for use with supported AJA devices and
compatible professional applications. Users can also load externally generated
LUT files into the Io IP to ensure consistent color among different devices.
NOTE: .cube files are the new standard for importing and exporting LUTs with AJA
Control Room as of v16.2. Prior to v16.2, Control Room supported CSV files
containing LUT information. While this LUT formatting is still supported for
import, it is no longer supported for export.
The bit depth of LUT files depends on the version of firmware installed into Io IP.
• When s2110 or s2022 firmware is installed, the Io IP creates and uses 10-bit LUT
files.
• When s2110-RGB firmware is installed, the Io IP creates and uses 12-bit LUT
files.
• 10-bit LUT files can only be used with 2110 and 2022 firmware, and 12-bit LUT
files can only be used with s110-RGB firmware.
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.
NOTE: The displayed curves are approximate,. Curves for some extreme settings may
diverge significantly from the actual transfer functions.
