General Curve Tips
Although adjusting the Curve path type Tension, Continuity, and Bias con-
trols can feel like a guessing game, here are some general tips to help you
build desired effects in a timely manner:
• Tension in the minus direction (up to -1.0) creates bigger, looser curves.
• Continuity at +1.0 is the same as S-Linear motion.
• Continuity in the plus direction gives a bigger bounce, with +2.0 a good
value.
• Bias in the plus direction makes the curve happen after the keyframe.
• Bias in the minus direction makes the curve happen before the key-
frame.
Cutting and Pasting Path Values
Being aware of how Curve values may change during editing can help you
successfully fine tune the paths of edited effects.
• When keyframes are cut and pasted to and from the clipboard, the path
type (Curve, Linear, S-Linear) is retained for each keyframe.
• When a block of Curve path keyframes are cut and pasted, the first and
last keyframes in the block are given Tension = 1.0, Continuity = 0.0,
and Bias = 0.0 values. This helps merge the path with neighboring path
settings, since the Curve path requires three keyframes for proper cal-
culation. Intermediate Curve path keyframes in the marked block
retain their original values, since the neighboring keyframes required
for the calculation exist.
• Cutting or copying a single keyframe with a Curve path type is handled
the same as a first or last keyframe, and so this keyframe is given
Tension = 1.0, Continuity = 0.0, and Bias = 0.0 values.
• If you paste a keyframe with a Curve path into the middle of an effect,
reset Tension values to 0.0.
Controlling Smooth Path Windup
Effects with a curved transform path may move back slightly in the oppo-
site direction when the move begins or ends. This “windup” is a character-
istic of Curve path control, which is the factory default path type applied to
new effect keyframes. Curve requires three keyframes for proper interpo
-
lation, so values for the previous (or next) keyframe affects the path
through the next (or previous) keyframe.
