3D lookup table controls provide independent adjustments
for the red, green and blue color channels
Importing and Exporting 3D LUTs
Current HDLink models support the popular Autodesk .3dl, IRIDAS .itx and IRIDAS .cube lookup
table formats when importing 3D LUTs. Click the Load Table button to load lookup tables.
Built-in lookup tables can be loaded for log to linear conversion
3D LUTs can also be exported from HDLink in the .cube format. HDLink uses the .cube format to
store 3D LUTs internally as this is a most memory efficient way to store complex lookup tables.
Both 3D LUTs created with curves in the lookup table interface, and 3D LUTs imported from
.3dl, .itx and .cube files, are exported from HDLink in the .cube format. Click the Save Table
button to save lookup tables.
The .cube file format is fully compatible with current and previous Blackmagic Design products
which share the same LUT format: HDLink Pro 3D, HDLink Optical Fiber, HDLink Pro DVI Digital,
Multibridge Eclipse, Multibridge Pro (October 2007 model) and DeckLink HD Extreme 2.
Importing and Exporting 1D LUTs
All HDLink models can import 1D LUTs. The 1D file format is any tab-delimited text file with red,
green and blue values for each record and the first line (title line) is skipped. Lookup tables
need to be 1024 records long with the first line reserved for the title line. Check out the sample
1D lookup table accompanying the HDLink software installer. 1D lookup tables can be created in
a spreadsheet program and then must be exported to a 'tab separated' text file prior to being
imported in to HDLink Utility. Click the Load Table button to load lookup tables.
