Tracker Sizes
In addition to onscreen controls, each tracker has a set of sizing parameters that let you adjust
the pattern and search box.
Pattern Width and Height: Use these controls to adjust the width and height of the
selected tracker pattern manually. The size of the tracker pattern can also be adjusted
in the viewer, which is the normal method, but small adjustments are often easier to
accomplish with the precision of manual controls.
Search Width and Height: The search area defines how far Fusion will look in the
image from frame to frame to reacquire the pattern during tracking. As with the Pattern
Width and Height, the search area can be adjusted in the viewer, but you may want to
make small adjustments manually using these controls.
Tracked Center
This positional control indicates the position of the tracker’s center. To remove a previously
tracked path from a tracker pattern, right-click this parameter and select Remove Path from the
contextual menu.
X and Y Offset
The Offset controls help to create a track for objects that may not provide very well defined or
reliable patterns. The Offset controls permit the tracking of something close to the intended
object instead. Use these Offsets to adjust the desired position of the path, while the tracker
pattern rectangle is positioned over the actual tracking location.
The Offset can also be adjusted directly in the viewer by activating the Offsets button in the
viewer toolbar.
The tracker offset icon
in the upper left of the
viewer is used to offset the
tracking pattern from the
intended object
