Keep in mind that since you can apply both 1D and 3D LUTs simultaneously, 1D LUTs at each step are
always applied before 3D LUTs.
– Input Lookup Table: Two drop-down menus let you add 1D and/or 3D LUTs that process the
current Timeline before every other image processing operation in DaVinci Resolve.
– Output Lookup Table: Two drop-down menus let you add 1D and/or 3D LUTs that process the
current Timeline after the operations applied in the Color page, but before the temporarily applied
Display LUT.
– Video Monitor Lookup Table: Two drop-down menus let you add 1D and/or 3D LUTs that process
the current Timeline after every other image processing operation in DaVinci Resolve. However,
Display LUTs are only temporarily applied for purposes of monitoring; they’re never applied to
rendered media, or to the signal that is output to tape using the controls in the Deliver page.
Display LUTs are particularly valuable for applying a film print emulation LUT in a Log workflow, or
for applying a monitor calibration LUT if you’re outputting to a single display and you don’t have
dedicated outboard calibration hardware.
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.
– 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.
– 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.
