Chapter 12 Keyframing 456
Keyframes and eect duration
When you change the duration of an eect such as a lter or behavior in the Timeline, the
timing of all keyframes applied to that eect is scaled proportionally. This means that keyframed
changes to an eect speed up or slow down if the eect is shortened or lengthened. This
happens whether you change the duration of the eect object bar, or the duration of the image
object bar an eect is applied to.
Note: Object parameters such as Position, Rotation, Scale, Opacity, and so on are not aected.
If you press Command while resizing an object bar that has eects applied, the object bar is
trimmed without altering the timing of any keyframes. You can also prevent automatic keyframe
retiming by pressing Command while changing the duration of an eect object bar.
Keyframe Editor
Keyframe Editor overview
When you create two or more keyframes, Motion generates interpolated parameter values for
the frames that come between. These changing parameter values are represented by curves the
Keyframe Editor. Using the Keyframe Editor, you can view and modify these curves to animate
objects and eects in your project.
