Using a Tracker node in line for a match move.
Setting the Operation parameter in the Operation tab in the Inspector to Match Move, Corner
Position, or Perspective Position always applies the motion to the foreground input (if one is
connected). This is an easy workflow for simple situations. In this scenario, you can use the
Tracker node to replace a Merge node since Tracker nodes include all the same functionality
as a Merge.
Using a Tracker node to do a match move and merge, all in one.
Method 2: Connect specific parameters to the Tracker Node
Alternatively, you can connect the tracking data from the Tracker node to the specific
parameters of other nodes that will actually do the work, for instances where setting up a match
move isn’t just a matter of transforming a foreground image. Each Tracker node and each
pattern within the Tracker node publishes its data for other nodes to use without directly linking
to them in the node tree. For example, in the following node tree, an Ellipse node is being used
to isolate a glow effect for the ray gun prop.
The Tracker set up as a branch and connected using the Connect To menu.
