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.
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 – SDI to HDMI 12G. You can output the 3D LUT
on the SDI 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

The ‘audio’ tab for Teranex Mini – SDI to HDMI 12G contains the following settings.
Audio Output Menu
Set XLR Output
You can choose between analog and AES/EBU output by highlighting the ‘analog,’ ‘AES/EBU,’
or ‘timecode’ buttons in the ‘audio output’ menu. When you select ‘timecode’ the left XLR
connector will output analog audio, while the right XLR output will provide a timecode signal.
Depending on which audio output option you select, you can then pick which audio channels of
your SDI input to send to your HDMI, AES/EBU, or Analog audio output, as well as adjusting
their gain per channel or channel pair. If you are outputting AES/EBU audio via both XLR
connectors, you can select up to four channels. If you are outputting analog audio, you can
select up to two channels. If you are using the right XLR connector to output a timecode signal,
the left XLR connector will output one channel of analog audio.
Your Teranex Mini will retain its last settings whether applied via switch, Smart Panel or Teranex
setup utility. If reverting to switch control after removing the Smart Panel or updating your
converter’s settings via software, you may need to toggle individual switches for new settings to
take effect.
