Tip: To save time, you can have Final Cut Pro automatically duplicate a clip in the Timeline and
apply an effect to the duplicated clip by holding down the Control key while you drag an effect
from the Effects Browser to the clip in the Timeline. You can also apply an effect to every clip in
an audition by holding down the Option key and the Control key while you drag the effect from
the Effects Browser to the audition in the Timeline. In both cases, you must start dragging the
effect from the Effects Browser and then press the keys as you add the effect to the clip.
Retime clips to create speed effects
Retiming clips overview
You can adjust a clip’s speed settings to create fast-motion or slow-motion effects. You can also
reverse a clip, rewind a segment of a clip, apply variable speed effects (also called speed ramping)
to a clip selection, and create instant replays and jumpcuts. By default, Final Cut Pro maintains
the audio pitch of any speed adjustment, but you can turn off this feature to accentuate the
speed effect.
You can’t apply speed changes to still images, generators, titles, and themes in Final Cut Pro.
Change clip speed
In Final Cut Pro you can make both constant and variable speed changes to your clips while
preserving the audio’s pitch.
Note: Speed settings are applied to the specific instance of the selected clip only. They are not
applied to that clip’s source media file on disk. To create a media file with the applied speed
effects, export the clip as a QuickTime movie. For more information, see
on page 400.
Apply a constant speed change
Applying a constant speed change to a range selection or a whole clip alters the selection’s
playback speed by a uniform percentage. For example, applying a speed setting of 25 percent to
the selection makes the entire selection play in slow motion.
