Both the speed and duration of the segment change. Speeding up a segment of a clip makes the segment shorter, and
slowing down a segment makes it longer.
4 (Optional) To create a speed transition, drag the right half of the speed keyframe to the right, or the left half to the left.
A gray area appears between the halves of the speed keyframe, indicating the length of the speed transition. The rubber
band forms a ramp between the two halves, indicating a gradual change in speed occurring between them. A blue curve
control appears in the gray area.

5 (Optional) To change the acceleration or deceleration of the speed change, drag either of the handles on the curve
control.
The change of speed eases in or eases out according to the curvature of the speed ramp.

1 In a Timeline panel, click the Clip Effect menu and choose Time Remapping > Speed. (The Clip Effect menu
appears next to the filename of every clip in a video track. Zoom in, if necessary, to make enough room in the clip
to display the menu.)
A horizontal rubber band that controls the speed of the clip appears across the center of the clip. The clip is shaded in
contrasting colors above and below the 100% speed demarcation. A white speed control track appears in the upper
portion of the clip, just below the clip title bar.
