Basic Node Setup
The example below uses a Planar Transform node between a masked MediaIn2 node and the
foreground input to a Merge node. The background MediaIn1 node connects to the Planar
Tracker, which was used to generate the Planar Transform. Once the Planar Transform is
created, the Planar Tracker is no longer needed in the node tree.

Inspector
Controls Tab
The Planar Transform node has very few controls, and they are all located in the Controls tab.
It’s designed to apply the analyzed Planar Tracking data as a match move,
Reference Time
This is the reference time that the pattern was taken from in the Planar Tracker node used to
produce the Planar Transform.
Right-Click Here for Track Spline
The Track spline contains information about the perspective distortions stored in 4 x 4 matrices.
When a Planar Transform node is exported from a Planar Tracker node, the Track spline
produced by the Planar Tracker is shared by connecting it with the Planar Transform node. A
consequence of this sharing of the Track spline is that if the track is changed in the Planar
Tracker node, the Planar Transform will be automatically updated. Note that this spline can be
examined in the Spline Editor, which is useful for seeing the extent of tracked frames.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other Tracking nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
