33 Point 3D LUT
Your Teranex Mini SDI to DisplayPort 8K HDR supports .cube 3D LUT files that can be created
in any color correction software such as DaVinci Resolve. DaVinci Resolve can save color
grades as 3D LUTs.
You can load two separate 3D LUTs by clicking on the ‘load’ button for each 3D LUT slot,
selecting the desired .cube file from your computer, and clicking ‘Open’. Click ‘save’ to confirm
your settings. The 3D LUT filename will appear above each ‘load’ button so you know which
3D LUT is being used for 3D LUT 1 or 3D LUT 2.
To turn a 3D LUT on, simply click the ‘use 3D LUT 1’ or ‘use 3D LUT 2’ options. To turn the
3D LUT off, click the ‘bypass 3D LUT’ option.
TIP You can also enable a 3D LUT by pressing the 1 or 2 buttons on the unit’s
front panel. Press the buttons again to turn a 3D LUT off.
Bypass 3D LUT
Click on this button disable all 3D LUTs so the DisplayPort output does not have a 3D
LUT applied.
Clear
Click on this button to remove 3D LUT 1 or 3D LUT 2 from your converter’s internal memory.
Load
Click on the ‘load’ button to load a 3D LUT from your computer.
Save As
Click on the ‘save as’ button to save a loaded 3D LUT to a folder on your computer. After you
generate a calibration 3D LUT, it is important to save it your computer.
What is a 3D LUT?
A 3D LUT, or ‘3D Lookup Table’, is a file containing table of values that are used to modify
the video colorspace to a new set of RGB values in a 3D cube space.
The color cube contains all the variations between the mix of each primary color, defined
within three x, y, z spatial dimensions. This means the RGB channels in the SDI input
video can be remapped to any other RGB output color in the DisplayPort video output.
This is very powerful as it means any color can be mapped to any other color so you can
perform very precise color adjustments for calibrating displays, or loading log gamma
curves for display when working with different types of raw camera files on set where you
want to see linear gamma.
To show how powerful 3D LUTs can be, one of the default LUTs loaded can convert your
input video to black and white. This shows that all the input RGB colors are remapped via
the 3D LUT to black and white RGB output values via the DisplayPort output.
You can create your own 3D LUTs and upload them via the admin software and DaVinci
Resolve even allows you to convert a color grade setting to a 3D LUT that you can then
upload to your Teranex Mini SDI to DisplayPort 8K. The 3D LUT on the DisplayPort output
is optional, and the SDI video loop output is a clean feed.
For more information on how to create a 3D LUT .cube file, refer to the DaVinci Resolve
manual which you can download from the Blackmagic Design website at
