n
You can often adjust a failed tracker by increasing the Failure Threshold value. Typically the
Failure Threshold accuracy should be at least 90 percent for an accurate result. It is also
recommended that the Failure Threshold is close to or slightly below the Auto Update
Threshold value.
Transform Tab (Motion Stabilizer)
The Transform tab allows you to choose how to calculate the tracker data when you work
with more than one tracker.
Stabilize Direction menu Use for an image that is unstable on one axis but
moving on the other axis. The options include:
Any Direction. Stabilizes all motion.
X Only. Stabilizes the X axis of motion.
Y Only. Stabilizes the Y axis of motion.
Color
Specifies the color used to draw the average position
of the trackers. Requires the Search/Target tab set to
Draw/Average.
See “Working with the Corner Pin Tracker” on
page 497 for more information on the Draw Average
parameter.
Scale X
Scale Y
Scale the rendered image after tracker data is
applied.
If you want to adjust the scale of the image, you
should use these parameters instead of the Scale
parameters in the Shape tracks’s Position Tab, since
this filter performs its own rendering.
