Grain Softness
This slider controls the blurriness or fuzziness of the grain. Smaller values cause the grain to be more
sharp or coarse.
Grain Size
This slider determines the size of the grain particles. Higher values increase the grain size.
Grain Spacing
This slider determines the density or amount of grain per area. Higher values cause the grain to
appear more spaced out.
Aspect Ratio
This slider adjusts the aspect of the grain so that it can be matched with anamorphic images.
Alpha-Multiply
When enabled, this checkbox multiplies the image by the Alpha, clearing the black areas of any
grain effect.
Grain Spread controls
Spread Tab
The Spread tab uses curves for the red, green, and blue channels to control the amount of grain over
each channel’s tonal range.
RGB Checkboxes
The red, green, and blue checkboxes enable each channel’s custom curve, allowing you to control
how much grain appears in each channel. To mimic usual film responses, more grain would appear in
the blue channel than the red, and the green channel would receive the least. Right-clicking in the
spline area displays a contextual menu containing options related to modifying spline curves.
For more information on the LUT Editor’s controls see Chapter 105, “LUT Nodes,” in the
DaVinci Resolve Reference Manual or Chapter 45 in the Fusion Reference Manual.
In and Out
This control provides direct editing of points on the curve by setting In/Out point values.
