converter does not have to wait for the HDMI television or monitor to lock before displaying the
video output as the HDMI signal is already locked. It's important to note that this feature only
works when changing sources using the same video standard.
The HDMI instant lock feature can introduce a small delay in video and audio, so if you need
zero delay in your converted output you can bypass the HDMI instant lock feature by
deselecting the checkbox.
33 Point 3D LUT
Your Blackmagic Teranex Mini – Optical to HDMI 12G supports .cube LUT files that can be
created using DaVinci Resolve software, or other color correction software that can export .
cube files.
You can load 2 separate LUTs by clicking on the 'load' button for each LUT slot, selecting the
desired .cube file from your computer, and clicking 'OK'. Click 'save' to confirm your settings.
The LUT filename will appear next to each 'load' button so you know which LUT is being used
for LUT 1 or LUT 2.
To turn a LUT on, simply click the 'use LUT 1' or 'use LUT 2' checkboxes. To turn the LUT off,
click the 'bypass LUT' checkbox.
The 3D LUT can also be applied to your converter's loop output by checking the 'enable 3D
LUT on loop SDI output' checkbox. If you don't want the LUT applied to the loop output simply
deselect the checkbox.
If you have a Smart Panel installed, you can easily enable a LUT by pressing the 1 or 2 control
panel buttons. Press the buttons again to turn a LUT off.
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 color 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
or Optical input video can be remapped to any other RGB output color in the HDMI
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 HDMI 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 – Optical to HDMI 12G. You can output the 3D
LUT on the optical video loop output so you could even use your Teranex Mini as a
dedicated 3D LUT color processor even if you don't use the HDMI output!
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
