16 Changing Clip Speed
and Time Remapping
You can adjust a clip’s speed parameters to create
fast- or slow-motion effects. With time remapping,
you can create variable speed effects.
This chapter covers the following:
 Speed Basics (p. 307)
 Constant and Variable Speed Settings (p. 311)
 Making Constant Speed Changes (p. 314)
 Making Variable Speed Changes (p. 315)
Speed Basics
The default speed of all clips is 100 percent, but you can change a clip’s speed setting at
any time.
 Slow motion: Speed is under 100 percent.
 Fast motion: Speed is over 100 percent.
 Variable speed: Speed changes over time, using the time remapping feature.
You may have different reasons for changing the speed settings. You may want to solve
editorial problems in your sequence. In that case, you can do a fit-to-fill edit, making a
clip longer to fill more time or shorter if an action takes longer than you’d like. You can
use variable speed changes to create ramping speed changes from slow to fast motion,
and from forward to reverse. This allows you to make specific frames in a clip occur at
particular cues in your sequence. The rest of the frames in the clip are automatically
played faster or slower to compensate.
