Motion Tracking Workflow In Depth
Tracker nodes serve two purposes. They provide a method to analyze an object you want to
follow, and they serve as a container for the resulting track data. This allows you to use one
node for analysis and to pass on that analysis to any other node that requires it. Following is a
more detailed breakdown of the tracking process.
Connect the Image to Track
Regardless of whether you actually use the Tracker node itself to do anything with the tracking
data, the image you want to track must be connected to the background input (yellow) of a
Tracker node for there to be a successful analysis. While the Tracker node has a foreground
input, it is initially ignored for purposes of tracking analysis, so even if you connect a
foreground, the background is the only input used during the analysis process.

Add Trackers
Although each Tracker node starts with a single tracker pattern, a single node is capable of
analyzing multiple tracking patterns that have been added to the Tracker List, enabling you to
track multiple features of an image all at once for later use and to enable different kinds of
transforms. Additional trackers can be added by clicking the Add button immediately above the
Tracker List control.
