File LUT [FLU]
The FileLUT node
File LUT Node Introduction
The File LUT node applies a Lookup table (LUT) to the image: either a simple 1D LUT or a
supported 3D LUT. Unlike the Color Curves node, it does not use a spline-based LUT. Instead, it
loads the LUT from a file stored on your computer or server.
This approach has two advantages. The first is that the only part of the LUT stored in the
composition is the path to the file. Since LUT files can be large, this can dramatically reduce the
file size of a composition when several LUTs are present. The second advantage is that it
becomes possible to adjust all File LUT nodes using the same file at the same time, just by
changing the contents of the LUT. This can be useful when the same LUT-based color
correction is applied in many different compositions.
Inputs
The File LUT node includes two inputs: one for the main image and the other for an effect mask
to limit the area where the LUT is applied.
–
Input: This orange input is the only required connection. It accepts a 2D image
output that gets the LUT applied.
–
Effect Mask: The optional blue effect mask input accepts a mask shape created
by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.
Connecting a mask to this input limits the applied LUT to only those pixels within the
mask. An effects mask is applied to the tool after the tool is processed.
Basic Node Setup
The File LUT node can be placed after a MediaIn node in DaVinci Resolve or a Loader node in
Fusion Studio. Sometimes this setup is used to convert the camera-original image to linear color
space for compositing. Other times, as in the example below, the File LUT is applied at the end
as a grading LUT to apply a look from the colorist.
