Description Example Interpolation method
Lets you manipulate the keyframe curve manually
by dragging the handles. If multiple Bezier
keyframes are selected, or Bezier is applied to the
curve segment, the handles of all the selected
keyframes are modified. Bezier
This method behaves like Bezier interpolation, but
without access to the handles (they are calculated
automatically). The parameter begins to change
gradually, reaching its maximum rate of
acceleration at the midpoint, then it tapers off
slightly as it approaches the second keyframe.
When applied to a keyframe, the segments before
and after the keyframe are affected. When applied
to a curve segment, the segment between to the
two keyframe is affected. Continuous
A type of reverse-inertia effect, so that a value
change slows coming into a keyframe. When
applied to a curve segment, the value change
eases into the segment. Ease In
Creates a typical inertia-like lag, so that a value
change begins more slowly coming out of a
keyframe. When applied to a curve segment, the
value change eases out of the segment. Ease Out
Creates an exponential curve between the current
value and the next, changing the value slowly at
first, then reaching its maximum rate of
acceleration as it approaches the next value. Exponential
Creates a logarithmic curve between the current
value and the next, changing the value rapidly at
first, then slowing drastically as it approaches the
next value. Logarithmic
Alternatively, you can apply an interpolation method to the entire parameter. In the
following example, the Y Position curve (green) is currently set to Linear.
