User Manual

Correct Edges
The Correct Edges checkbox is only displayed once the Use Object or Use Material
checkbox is enabled. When the Correct Edges checkbox is enabled, the Coverage and
Background Color channels are used to separate and improve the effect around the
edge of the object. When disabled (or no Coverage or Background Color channels are
available), aliasing may occur on the edge of the mask.
Motion Blur
For nodes that are capable of introducing motion, such as Transform nodes, Warp nodes, and
so on, the Motion Blur checkbox toggles the rendering of motion blur on or off for that node.
When this checkbox is enabled, the node’s predicted motion is used to produce the blur
caused by a virtual camera shutter. When the control is disabled, no motion blur is created.
When Motion Blur is disabled, no additional controls are displayed. However, turning on Motion
Blur reveals four additional sliders with which you can customize the look of the motion blur
you’re adding to that node.
Quality
Quality determines the number of samples used to create the blur. The default quality
setting of 2 will create two samples on either side of an object’s actual motion. Larger
values produce smoother results but will increase the render time.
Shutter Angle
Shutter Angle controls the angle of the virtual shutter used to produce the Motion Blur
effect. Larger angles create more blur but increase the render times. A value of 360 is
the equivalent of having the shutter open for one whole frame exposure. Higher values
are possible and can be used to create interesting effects. The default value for this
slider is 100.
Center Bias
Center Bias modifies the position of the center of the motion blur. Adjusting the value
allows for the creation of trail-type effects.
Sample Spread
Adjusting Sample Spread modifies the weight given to each sample. This affects the
brightness of the samples set with the Quality slider.
Scripting
Scripting fields are present on every node and contain one or more editable text fields that can
be used to add scripts that process when that node is rendering. For more information on the
contents of this tab, please consult the Scripting documentation.
Comments
A Comments field is found on every node and contains a single text field that is used to add
comments and notes to that node. To enter text, simply click within the field to place a cursor,
and begin typing.
When a note is added to a node, the comments icon appears in the Control Header and can be
seen in a node’s tooltip when the cursor is placed over the node in the Node Editor. The
contents of the Comments tab can be animated over time, if required.
Additional controls appear under this tab if the node is a Loader. For more information, see
Chapter 89, “Generator Nodes.” In the DaVinci Resolve manual or Chapter 38 in the Fusion
Studio manual.
