Chapter 2 Motion Tracking 101
 Tracking behaviors pop-up menu: Choose from a list of tracking data (from other
tracking behaviors) within the project.
Movement: The Movement parameter contains controls to begin the tracking analysis
and to specify the direction of the analysis.
 Analyze: Click the Analyze button to begin the motion tracking analysis. Once
Analyze is clicked, a status window appears that displays the tracking progress. To
stop the analysis, click the Stop button in the status window or press Esc.
The start of the track is based on the current playhead position, rather than the start
of the behavior in the Timeline.
 Reverse: When the Reverse checkbox is turned on, the clip is analyzed from the
current playhead position to the first frame of the clip (or the first frame of the
tracking behavior).
Note: You must move the playhead to the frame from which you want to begin the
reverse analysis.
Type: This pop-up menu allows you to choose between one-point, two-point, or four-
point tracking.
 Transformation: This option allows one-point or two-point tracking, transforming
the destination object.
 Four Corners: This option enables four-point tracking, corner-pinning the
destination object. When this option is chosen, the Direction and Adjust parameters
are no longer available.
Note: The Four Corners option is not available when Match Move is applied to a 3D
group. To corner-pin a 3D group, turn on the Flatten checkbox in the Group tab of
the Inspector.
Direction: This pop-up menu allows you to specify the dimension to which the
recorded movement is applied to the destination object: X and Y, only X, or only Y.
Transform: This pop-up menu allows you to choose how the destination object (the
object to which the Match Move behavior is applied) moves.
 Attach to Source: This option “glues” the foreground object to the recorded track or
animation source. Use Attach to Source when the source object is scaling or rotating,
and you want the destination object to “stick” to a particular spot on the source
object. Any animation that existed on the destination object prior to applying the
track is erased.
Note: Although the destination object is attached to the movement of the source
object, the position of the destination object can be changed (offset from the source
object). The destination object cannot be scaled or rotated.
