Using Blend Nodes
Blend nodes include the Colour Blend (CBlend) and Matte Blend (MBlend) nodes.
A blend node is essentially a container that you can use to create a mini-composite at different parts of
the pipeline. CBlend and MBlend nodes each comprise one or more layers that include the components
needed for a composite: a front, matte, and back component. These components are referred to as pipes,
and they may contain as many nodes as needed to create the desired image.
NOTE The back component is not represented visually as it is applied automatically to the composite.
(a) The Front and Matte pipes of the blend node constitute one layer.
The back component is not represented visually as it is applied automatically to the composite.
Nodes on the pipes are processed sequentially, with a single input and single output to and from each node.
Therefore, you cannot add multiple input nodes that require several clips to pipes. However, some multiple
input nodes can operate with only one input source, for example, the Gmask, Colour Correct, and Regrain
nodes. If you add one of these node types to a blend node pipe, it is converted to a single-input node.
You can animate the curves in the MatteCurves, CBlend, MBlend, Colour Curves, or Result nodes.
Colour Blend Node
Use Colour Blend (CBlend) nodes to set up the colour operations you want to perform on a clip.
With a CBlend node, you can:
Use the Front pipe of a layer to adjust the colour of a clip.
Use the Matte pipe of a layer to isolate a region of the image to which the colour adjustments will be
applied. With no matte, the colour correction is applied to the entire image.
Blend the front and back images for each layer.
Create layers of colour corrections for your front clip.
