User Manual

The following controls are common to most nodes, although some are node-specific.
For example, Motion Blur settings have no purpose in a Color Space node.
Blend
The Blend control is found in all nodes, except the Loader, MediaIn, and Generator nodes. It is
used to blend between the node’s unaltered image input and the node’s final processed
output. When the blend value is 0.0, the outgoing image is identical to the incoming image.
Ordinarily, this will cause the node to skip processing entirely, copying the input straight to the
output. The default for this node is 1.0, meaning the node will output the modified image 100%.
Process When Blend is 0.0
This checkbox forces the node to process even when the input value is zero and the image
output is identical to the image input. This can be useful on certain nodes or third-party plug-ins
that store values from one frame to the next. If this checkbox is disabled on nodes that operate
in this manner, the node will skip being processed when the Blend is set to 0, producing
incorrect results on subsequent frames.
Red/Green/Blue/Alpha Channel Checkboxes
Most nodes have a set of RGBA checkboxes in the Settings tab. These checkboxes let you
exclude any combination of these channels from being affected by that node.
The channel limiting checkboxes in the
Settings panel of a Transform node set so
that only the green channel is affected.
For example, if you wanted to use the Transform node to affect only the green channel of an
image, you can turn off the Red, Blue, and Alpha checkboxes. As a result, the green channel is
processed by this operation, and the red, blue, and alpha channels are copied straight from the
node’s input to the node’s output, skipping that node’s processing to remain unaffected.
Transforming only the green color channel of the
image with a Transform effect.
