About keyframing
To change an effect over time, you can use a standard technique known as
keyframing
.
When you create a keyframe, you specify the value of an effect property for a specific point
in time. When you apply different values to keyframes, Adobe Premiere Pro automatically
calculates the values between the keyframes, a process called
interpolation
. For example,
to create a blur that first increases and then decreases over time, you would need to set
three keyframes for a blur effect—the first with no blur, the second with the maximum
amount of blur, and the third with no blur. Because Adobe Premiere Pro automatically
interpolates the blur values between each keyframe, the blur gradually increases between
the first and second keyframes and then gradually decreases between the second and
third keyframes.
You can set keyframes within the clip’s duration for most Standard effects. You can also
animate clips by setting keyframes for Fixed effect properties, such as Position and Scale
(see
“Manipulating a clip in the Program view” on page 252
). You can also move, copy, or
delete keyframes and change the interpolation method of a keyframe. The following
sections explain how to view, add, and adjust the value and timing of keyframes as well as
the interpolation method they use. For more information on keyframe interpolation, see
“Working with keyframe interpolation” on page 251
.
Note:
Some Adobe Premiere Pro effects cannot be animated with keyframes. See the
individual effect for more information.
Highlighted frames indicate where Blur effect keyframes are placed in the timeline. The Blur effect is
interpolated for in-between frames.
Activating keyframes
To animate an effect property, you must activate keyframes for that property. Any effect
property that allows keyframes includes a Toggle Animation button that you use to
activate keyframes. Once keyframes are activated, you can add and adjust as many
keyframes as you need to the property.
