Tracker Palette Modes
The Tracker palette’s Option drop-down menu lets you choose between Window mode (for
matching a window to the motion of a feature in the frame), Stabilizer mode (for subduing
unwanted camera motion.; for more information on Stabilizer mode, see Chapter 133, “Sizing
and Image Stabilization”), and FX mode (for tracking position to be used with ResolveFX or
OpenFX plug-ins).
Types of Tracking
A pop-up menu below the Tracker graph lets you choose whether to use the Cloud Tracker or
the Point Tracker.
The tracker type pop-up
There are two options:
The Cloud Tracker: Automatically analyzes all parts of the image for trackable points,
and uses these to automatically figure out the motion in the shot that you want to use to
move a Power Window or stabilize a shot. This tracker type is great for quickly tracking
a window to match the movement of almost any feature, with a minimum of work.
The Point Tracker: Lets you create one or more tracker crosshairs that you can
manually position in order to track specific features in the shot. The more crosshairs
you create and position, the more accurate the track can be. The Point Tracker is
incredibly useful in situations where you need to follow the motion of a very specific
feature in the frame. It can also be useful in cases where you want to stabilize a shot
that has many subjects moving in different directions, and it’s difficult to obtain a good
result with the CloudTracker.
Object Tracking
The object tracking controls provide the most basic tracking functions, some of which are
mirrored within the Color > Tracker menu.
Choose which type of transform you want to track before tracking
A series of five checkboxes let you turn on and off which transforms you’d like motion tracking
to apply automatically to the window. These checkboxes must be selected before you perform
a track in order to restrict the transforms that are used.
Pan and Tilt: Enables tracking of horizontal and vertical position, when you want to
transform a window to follow the location of a tracked subject.
Zoom: Enables tracking of size, when you want to transform a window to resize to follow
a tracked subject.
Rotate: Enables tracking of orientation, when you want to transform a window to rotate
with a tracked subject.
Perspective 3D: Enables tracking of pitch and yaw in 3D space, when you want a
window to skew to follow the orientation of a tracked subject within the scene. Good
when you want the window to “stick” to a surface.
