
Lock Scale to prevent the Tracker from automatically compensating when the
scale of the tracked region grows or shrinks during motion.

Likewise, when Rotation is locked, the orientation of Tracker output is
constrained.

The Aspect Ratio lock forces the Tracker to conform to a square (1:1), or
rectangular (4:3 or 16:9) shape.
Hint: Generally, locking channels in this manner make it easier to obtain a very steady motion track; but
just as often, your choices will be dictated by creative requirements.

The Tracker is designed to follow the largest shape
in a frame that meets the defined color criteria. At
times, similar colored articles or inclusions in the
frame can interfere with Tracker output.
The settings in this group allow you to limit the area
of the frame the Tracker monitors, which can help
you sidestep this issue.
We’ll discuss the application of the Tracker’s data stream when discussing the Positioner tools.
