The path concept can also be applied to functions that do not move a picture across
the screen, like matte hue changes. For these functions, the rate of change of the
parameter follows the same path types above. For example, an S-Linear hue rotation
will accelerate and decelerate the speed of the hue change at the beginning and end
of the keyframe.
2.11.9.2 Tension, Continuity, and Bias Controls
When the CURVE parameter is selected, additional fine-tuning path controls
become available:
•
TENSION — Controls the length of the tension vector. At a setting of 0.0, this
imaginary line extends an equal distance into and out of the keyframe, and the
path through the middle keyframe is curved.
•
CONTINUITY — Determines the angle of the path into and out of the keyframe.
•
BIAS — Determines whether the path will be pulled towards the previous or the
following keyframe.
In the following examples, a physical path is shown between three keyframes.
The first keyframe (KF1) is the upper left square; the last keyframe (KF3) is the
lower right square. The adjustments in these examples are applied to the
middle keyframe only (KF2).
