(There is no comparable “advanced position” fixer or filter.)
■ Boosting Boosting filters are the opposite of blurring filters. They increase,
rather than decrease, changes in the track. Boosting filters are helpful if
you want to make a track have more exaggeration or a little more jerkiness.
See
Blurring, Smoothing, and Boosting parameters on page 4506.
■ Sub Anims The Sub Anims filter manages sub-animation of biped objects.
Clicking a button that corresponds to a transform (Position, Rotation, or
Scale) displays a dialog that lets you assign a controller to that transform.
Assigning a controller in this way assigns it only to the selected biped parts.
This is very handy for adding controllers to multiple biped parts all at once.
Also includes the ability to enable or disable the three list controllers
selectively, and avoids creating SubAnims, where they already exist.
See
Sub Anim parameters on page 4507.
■ Key Reducer Creates tracks with fewer keys, by removing certain keys
based on tolerance and key spacing parameters. This works similarly to
how key reduction works during motion-capture import.
See
Key Reducer parameters on page 4507.
■ Knee Wobble Corrects knees that wobble or shake when a foot is planted.
If the knee is determined to wobble by the filter, the center of mass object
is adjusted to eliminate the wobble.
■ Knee Extension Corrects knees that overextend when a foot is planted.
If the knee extension is identified by the filter, the center of mass object
is adjusted to eliminate the extension.

Width Width is the size of the filter kernel width in frames. It tells you how
much of the animation is taken into effect when filtering a specified keyframe.
Damping The Damping value changes how effective the filter should be. A
higher value, the more dramatic the change. A damping value of 1.0 is normal
filter behavior
