Keyframe Path Control
Keyframe Path Control
Tension, Continuity, and Bias Controls
The path that an effect takes between keyframes may be adjusted
through the
CURVE path type selection from the Keyframe Path
Menu.
If CURVE is selected, three soft knobs are provided to control the
three parameters of the vector. These are labeled: Tension,
Continuity, and Bias.
The adjustment of these controls can affect the keyframe path in
various ways. Interactions between the controls are numerous
and each will be described in the following paragraphs. You may
want to experiment with the interactions by adjusting the controls
in small increments.
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).
