Action Source Nodes
Use source nodes in Action to create more advanced techniques such as transforming or replacing a front
or matte clip or applying motion blur. Source nodes can be used to separate front and matte clips in media
and then apply separate transformations to each clip. For example, if you apply media to a surface and you
want to create an effect where the matte moves into the scene, add a source that isolates the matte clip. A
matte source lets you animate the matte's position separately from the front. You can also use source nodes
to apply several matte clips to a single front clip.
Source nodes are applied before any Media list effects, such as the Modular Keyer, and may lead to unwanted
effects. For example, a Modular Keyer effect applied on a media layer is also applied to the Source node. If
you do not want to apply the Modular Keyer effect on a Source node, you need to create a new media layer
for the source node output.
When working with Source nodes, global Scene Ambient lighting has no effect. Therefore, when you add a
Source node, a Light node parented to a Camera node is automatically attached to the Source node. This
light is an ambient type, and appears at half the distance of the source camera.
Creating a Matte or Front Source
When you create a matte or front source, a new branch appears in the schematic showing the matte or front
clip is separated from its media, ultimately replacing the matte or front with itself. This method of using
source nodes lets you animate the media's matte or front separately.
To create a matte or front source:
1 In Action, click Media.
2 In the Media list, select the matte or front media that you want to replace.
3 Do one of the following:
■ Drag the Source Matte or Source Front node from the node bin and place it in the schematic.
■ Double-click the Source Matte or Source Front node. You do not need to be in Schematic view to
add a node in this manner.
