Blackmagic Teranex Setup Settings
The Teranex setup utility can change all the same settings that are available using the switches,
plus additional settings. You can access these settings by moving between the 'video,' 'audio,'
'configure,' and 'about' tabs.
The 'about' and 'configure' tabs are detailed in the 'changing settings' section in this manual.
The 'video' tab for Teranex Mini – SDI to HDMI 12G contains the following settings.
Video Output Menu
Clip HDMI Output to Legal Levels
This checkbox controls clipping of your SDI input to ensure that it stays within HDMI legal levels
and should be kept on by default.
HDMI Instant Lock
Select this checkbox to enable the HDMI instant lock feature. When HDMI instant lock is
enabled, the HDMI output signal is kept active even when changing sources. This means your
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 – SDI 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
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.
