If you drag the retiming handle to the left, the speed of the selection increases,
the duration of the selection decreases, and the bar above the Timeline selection
turns blue.
Drag the retiming handle

a fast-motion effect.
Apply a variable speed change
To alter the speed of a clip over time, in forward or reverse motion, you can apply
a variable speed change (also called speed ramping). Variable speed changes create
sophisticated eects in which subjects appear to smoothly shift across a variety of
dierent speeds, with gradual or abrupt transitions between each speed segment.
These types of eects can be seen in many music videos and broadcast commercials,
and the eects can be created directly in the Timeline. To apply variable speed eects,
you divide a clip into speed segments that are set to specic speed percentages.
1 In the Timeline, select either a range within a clip or a whole clip to which you want to
apply a speed ramp eect.
2 Do one of the following:
 To ramp the speed down: Choose Speed Ramp > “to 0%” from the Retime pop-up
menu in the toolbar.
 To ramp the speed up: Choose Speed Ramp > “from 0%” from the Retime pop-up
menu in the toolbar.
