Press Command-V or Control-V to paste the keyframes.
The keyframes are pasted at the position of the playhead.
Modifying Curves
You can modify a curve type, and its repetition mode, as well as apply filter effects
(smooth, jitter extraction, and so on) to a curve.
To change a curve type:
1
Select the curve (drag over the curve, or select the curve in the Curve Editor
parameters list).
2
In the parameters list, choose a curve Type and select Hermite, Linear, CSpline, JSpline,
NSpline, or Step curve. The most commonly used curves are Hermite, JSpline, and Linear.
For more information on curve types, see “
Note: You can have only one curve type per curve.
You can also modify a value in the Val field of the parameters list.
A curve’s Cycle setting determines the behavior before the first keyframe and after the
last keyframe:
•
KeepValue (the default setting): The value of the first and last keyframes is kept before
the first keyframe and after the last keyframe.
•
KeepSlope: Continues the tangent.
•
RepeatValue: Repeats the curve between the first and last keyframes.
•
MirrorValue: Reverses and repeats the curve.
•
OffsetValue: Offsets and repeats the curve.
