312 Chapter 15 Geometry
Sometimes a motion track is successful, but the resulting motion path is too rough to
use in its original state. Oftentimes, irregular motion will expose an animated effect
that you’re trying to keep invisible. These may be seen as jagged motion paths.
In these cases, you can use the Tracking Curve Smoothness slider to smooth out the
motion path that’s created by the tracker.
To smooth a track:
1 Select a tracker in the Tracker List.
2 Adjust the Tracking Curve Smoothness slider until the motion tracking path is smooth
enough for your needs.
The Tracking Curve Smoothness slider is nondestructive. This means that the original
tracking data is preserved, and you can raise or lower the smoothing that’s applied to
the original data at any time if you need to make further adjustments. Lowering the
Tracking Curve Smoothness to 0 restores the tracking data at its originally analyzed state.
