2 Adjust the Tracking Curve Smoothness slider, dragging it to the right 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.
