Keyframe Path Control
Tension Control
In the example below, the keyframes are at right angles so the
TENSION
control operates on a 45° line drawn through the
keyframe. This line is referred to as the Tension Vector and is
parallel to a line drawn between adjacent keyframes (see
illustration).
The
TENSION
soft knob controls the length of the tension vector.
At a Tension setting of 0, this imaginary line extends an equal
distance into and out of the keyframe, and the path through the
middle keyframe is curved.
The unmodified KF2 is said to have a correction value of 0 (see
Example 1).
