Animation and keyframes

Changing keyframe interpolation for the Position property of the Motion effect
A Linear spatial keyframe B. Auto Bezier interpolation C. Continuous Bezier interpolation
Do one of the following:
1
• In the Effect Controls panel, right-click a keyframe marker.
• In a Timeline panel, right-click a keyframe.
Choose an interpolation method from the context menu:

Creates a uniform rate of change between keyframes.
Linear
Lets you manually adjust the shape of the graph, and the rate of change, on either side of a keyframe. You can
Bezier
create very smooth changes using this method.
Creates a smooth rate of change through a keyframe. As you change a keyframe's value, the Auto Bezier
Auto Bezier
direction handles change to maintain a smooth transition between keyframes.
Creates a smooth rate of change through a keyframe. However, unlike the Auto Bezier
Continuous Bezier
interpolation method, Continuous Bezier lets you adjust direction handles manually. As you change the shape of a
graph on one side of a keyframe, the shape on the other side of the keyframe changes to maintain a smooth transition.
Changes a property value without gradual transition (sudden effect changes). The graph following a keyframe
Hold
with the Hold interpolation applied appears as a horizontal straight line.
Slows down the value changes entering a keyframe.
Ease In
Gradually accelerates the value changes leaving a keyframe.
Ease Out
Note: Although interpolation methods can vary the rate at which a property changes between keyframes, they cannot
change the actual duration between keyframes. Duration is determined by the time (or distance in the time ruler) between
keyframes.

Control change using Bezier keyframe interpolation
Bezier handles are two-directional controls that change the curve of the line segment between the handle and the next
point on either side. The farther you pull a handle from its keyframe (center point), the more the line bends or curves.
The curve that you create by dragging the Bezier handle determines how smoothly the effect changes occur as the
animation property approaches and leaves a keyframe. These handles offer you more control over animation changes
than simply choosing a keyframe interpolation method. You can manipulate Bezier handles in either a Timeline panel,
the Effect Controls panel, or the Program Monitor.
