Vector Values

Path vector setting values of ± 1.0 are available, same as the Grass Valley
Group Kaleidoscope DPM.

Tension Control

In the example below, the keyframes comprise a right angle, 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 (

Figure 60

).

The

TENSION

soft knob controls the length of the tension vector. The length

of the tension vector is inversely proportional to its parameter value. For
example, at a Tension setting of 0 (zero), 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 correc-
tion value of 0.0.
