usually easier for editing keyframes of effects that have multiple, angular, or
twodimensional
values, such as Levels, Rotation, or Scale, respectively.
•
In the Timeline window, variations in keyframe values are indicated graphically, so you
can see at a glance how keyframe values change over time. By default, values change
between keyframes in a linear manner, but you can apply options that refine the rate of
change between keyframes. For example, you can bring motion to a gradual stop. See
“Working with keyframe interpolation” on page 251.
•
The Effect Controls window can display the keyframes of multiple properties at once,
but only for the clip selected in the Timeline window. The Timeline window can display
the keyframes for multiple tracks or clips at once but can display the keyframes of only
one property per track or clip.
•
Keyframes for audio track effects can be edited only in the Timeline window or in the
Audio Mixer. Keyframes for audio clip effects are like keyframes for video clip effects;
they can be edited in the Timeline window or in the Effect Controls window.
•
You can save space when you edit keyframes in the Timeline window because you don’t
need to open the Effect Controls window unless you want to set keyframe values
numerically. However, some options in the Effect Controls window can’t be represented
in the Timeline window, such as options in a pop-up menu.
Displaying keyframes in the Timeline window
By default, keyframes in the Timeline window are hidden. For video and audio effects, the
Timeline window can display the keyframes specific to each clip. For audio effects, the
Timeline window can also display the keyframes for an entire track. Each clip or track can
display a different property. However, within an individual clip or track, only one
property’s keyframes can be displayed at a time. You can specify which property’s
keyframes are currently displayed by using an effect properties pop-up menu available on
every clip or audio track in the Timeline window. This menu contains only the effects
already applied to that clip or track (see “Applying and controlling Standard effects” on
page 244).

The segments connecting keyframes form a graph that indicates changes in keyframe
values along the duration of the clip or track. Adjusting keyframes and segments changes
the shape of the graph.
