As you drag, the clip displays the adjusted speed as a percentage of its default (original)
speed.
Making Speed Changes in the Timeline
You can apply variable speed effects to clips using keyframes in the Timeline.
An effective way to create slow-motion and fast-motion effects is to use the keyframe
graph area of the Timeline. You can apply and adjust keyframes with the Pen tool to
create speed segments. You can slide the keyframes left or right in the keyframe graph
area to interactively create variable speed effects, or you can assign specific speed rates
to each segment. A keyframe is a special-purpose control that denotes a change in value
(in this case, a change in clip speed). For more information about keyframes, see
“Adjusting
Parameters for Keyframed Effects.”
To add speed keyframes to a clip in the Timeline
1 Do one of the following to display the keyframe graph area and the speed indicator tick
marks.
• Click the Clip Keyframes control in the lower-left corner of the Timeline.
• Press Option-T.
