LUT File Format Specification
LUT files are normal text files that contain 1025 lines (numbered 0 - 1024). Each
line contains 3 integer values in the range 0 - 1023, representing 10 bit R, G, B
component output values. Component values may be separated by one or more
commas, spaces, or tabs. The example below show LUT File contents for Line 0,
Line 1, Line 2, and Line 1024, with several valid ways to separate the numbers in a
line.
• 16, 17, 17
• 17 18 18
• 19 19 21
• …
• 1000, 1022, 1023
In the example above, the first line (Line 0) represents the output values for the
case where R=0, G=0, or B=0. In other words, if the R component of a pixel is set
to 0, then set R component value to 16. Likewise, if G is set to 0, then set G to 17.
The second line
(Line 1) does a similar thing for input component values equal to 1.
A simple way to construct a LUT file is to use a Spreadsheet like Excel. Simply fill 3
columns and 1025 rows with LUT data, and save the result as a “CSV” file.
Timecode Screen
The Timecode screen is used to select the timecode stream read for applications
that use it (for example, in AJA Control Room when the Timecode Source
preference is set to “Control Panel Setting” that application will read the selected
stream). This screen is also used for monitoring the RP-188 timecode embedded
in the digital data stream, for selecting a timecode offset (if required), and setting
timecode outputs.
