Note: It is best to apply time remapping controls to a clip in its own video track, or at least one not followed immediately
by other clips. Slowing any portion of a clip makes the duration of that clip longer. If a second clip immediately follows
the lengthened clip in the video track, the lengthened clip is automatically trimmed where the second clip begins. To
recover the frames trimmed from the lengthened clip, click the Track Select tool, Then Shift-drag the second clip toward
the right to make room. All clips lying to the right move to the right. Click the Selection Tool, then drag the right edge of
the lengthened clip to the right, exposing its trimmed frames.

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.

Ctrl-click (Windows) or Command-click (Mac OS) at least one point on the rubber band to set a keyframe. Speed
keyframes appear near the top of the clip, above the rubber band in the white speed-control track. Speed keyframes
can be split in half, acting as two keyframes for marking the beginning and end of a speed-change transition.
Adjustment handles also appear on the rubber band, in the middle of the speed-change transition.

of that portion. (Optional) Press Shift while dragging to limit the speed change values to 5% increments.
•
