Gaussian: This is very similar in speed and quality to Bi-Cubic.
Mitchell: This is similar to Catmull-Rom but produces better results with finely detailed
images. It is slower than Catmull-Rom.
Lanczos: This is very similar to Mitchell and Catmull-Rom but is a little cleaner
and also slower.
Sinc: This is an advanced filter that produces very sharp, detailed results; however, it
may produce visible “ringing” in some situations.
Bessel: This is similar to the Sinc filter but may be slightly faster.
Edges
This menu selects how the revealed edges are handled when the image is moved to match
position and scaling.
Black Edges: Out-of-frame edges revealed by Stabilization are left black.
Wrap: Portions of the image moved off frame to one side are used to fill edges that are
revealed on the opposite side.
Duplicate: The last valid pixel on an edge is repeated to the edge of the frame.
Mirror: Image pixels are mirrored to fill to the edge of the frame.
Position, Rotation, and Scaling Checkboxes (Match Move)
The Position, Rotation, and Scaling checkboxes appear only when the mode is set to Match
Move. They determine what components of motion that Stabilization will attempt to correct in
the image. For example, if only the Position checkbox is selected, no attempt will be made to
correct for Rotation and Scaling in the image.
Flatten Transformation (Match Move)
This checkbox appears only when the mode is set to Match Move. Like most transformations in
Fusion, Stabilization is concatenated with other sequential transformations by default. Selecting
this checkbox will flatten the transform, breaking any concatenation taking place and applying
the transform immediately.
Mapping Type
The Mapping Type control appears only in the Corner Positioning mode. There are two options
in the menu:
Bi_Linear: The first method is Bi-Linear, where the foreground image is mapped
into the background without any attempt to correct for perspective distortion. This is
identical to how previous versions of Fusion operated.
Perspective: The foreground image is mapped into the background taking perspective
distortion into account. This is the preferred setting since it maps better to the real
world than the older Bi-Linear setting.
Corner Selector (Corner or Perspective Positioning)
When the operation of the Tracker is set to either Corner or Perspective Positioning modes, four
drop-down menus appear. These options choose which trackers map to each of the four
corners of the rectangle. This is useful when a Tracker has more than four patterns selected,
and you must choose which patterns the positioners use.
