Here’s an example. It’s common, when grading for film output using a Log workflow,
that you’ll use the Display LUT drop-down menu to apply a film emulation LUT that
simulates the image as it will be output from the film recorder, taking into account the
film lab and print stock used, in order to make sure that the image you’re grading will
appear as close as possible to what the eventual release print will look like in
the cinema.
1D/3D Color Viewer Lookup Table: Two drop-down menus let you add 1D and/
or 3D LUTs that process the image shown in the Viewer on your computer display,
independently of the Display LUT that’s used to output to your broadcast display. By
default, this follows the Video Monitor LUT setting, but you can also use this option to
apply a specific calibration transform for your computer monitor. Alternately, you could
use it to desaturate the GUI Viewer to be able to specifically evaluate image contrast,
or if you don’t want to have to argue with your client over which display looks correct.
1D/3D Scopes Lookup Table: Ordinarily, DaVinci Resolve’s internal software video
scopes provide an unbiased analysis of the actual video data levels within the Resolve
image processing pipeline. However, you can choose to have the software scopes
use the Video Monitor LUT selection, or any other LUT installed on your system, to
transform this analysis to reflect the monitored output.
3D Lookup Table Interpolation: Lets you choose the processing quality of both
LUTand DCTL operations in DaVinci Resolve. 3D Lookup tables (LUTs) are 3D tables
of red, green, and blue values that specify an output color value for each input color
value, thereby providing a method of making color transformations using pre-calculated
data. While powerful, 3D LUTs have finite detail; for example, one might have a
17x17x17LUT that specifies 4913 individual color transforms. When applied to a floating
point image that contains more data than the LUT specifies transforms for, color
values falling between the 17x17x17 color transforms specified by the LUT need to be
interpolated. You can choose from two methods that trade off processing efficiency for
higher quality:
Trilinear: (Default) Trilinear is backward compatible with grades that use LUTs from
previous versions of DaVinci Resolve and matches the look of LUTs being applied in
other applications.
Tetrahedral: Tetrahedral is slightly more processor-intensive, but results in higher
image quality LUT and DCTL processing, with reduced color-banding. Tetrahedral
is recommended for projects that don’t need backward compatibility with previous
versions of DaVinci Resolve or LUTs created in other applications.
Update Lists button: Refreshes the LUT drop-down menus if you’ve added new LUTs
to your system since DaVinci Resolve has been opened.
Open LUT Folder button: This selection opens the master folder in your file system,
asdescribed in the list of DaVinci Resolve LUT paths shown above.
