The duration of a clip is the length of time it takes to play from the In point to the Out point. You can set a duration for video or audio clips, letting them speed up or slow down to fill the duration. You can do the same for still-image clips, but without the changes in speed. You can change the speed and duration for one or more clips at a time. You can also set clip speed to fill a duration by performing a four-point edit. 1 In a Timeline panel or Project panel, select one or more clips. Shift-click to select clips in a Timeline panel or a contiguous group in a Project panel. Ctrl-click (Windows) or Command-click (Mac OS) clips to select a noncontiguous group of clips in a Project panel.

USING ADOBE PREMIERE PRO
Effects and transitions
Last updated 1/16/2012
You can use frame blending to smooth the appearance of a speed effect that changes the time or frame rate of a clip.
To enable frame blending, choose Clip > Video Options > Frame Blend. For more information about frame blending,
see “
Blend frames for smooth motion
” on page
306.
The duration of a clip is the length of time it takes to play from the In point to the Out point. You can set a duration
for video or audio clips, letting them speed up or slow down to fill the duration. You can do the same for still-image
clips, but without the changes in speed.
You can change the speed and duration for one or more clips at a time.
You can also set clip speed to fill a duration by performing a four-point edit.
1
In a Timeline panel or Project panel, select one or more clips. Shift-click to select clips in a Timeline panel or a
contiguous group in a Project panel. Ctrl-click (Windows) or Command-click (Mac OS) clips to select a non-
contiguous group of clips in a Project panel. To change speed or duration of all the clips in a bin in the Project panel
and its nested bins, select the bin. The change does not affect non-media clips, such as Sequences and offline clips,
in the bin.
2
Choose Clip > Speed/Duration.
3
Do any of the following:
To change the duration without changing the speed of the selected clips, click the gang button so that it shows a
broken link
. Unganging also allows you to change the speed without changing the duration.
The speed remains at the percentage set while you trim the clip or clips. Alternatively, the duration remains at the
percentage set while you change the speed of the clip or clips.
To play the clips backward, check Reverse Speed.
To keep the audio at its current pitch while the speed or duration changes, check Maintain Audio Pitch.
To keep the clips following the changing clips adjacent to them, click Ripple Edit, Shifting Trailing Clips. (This
option is available only when changing the speed or duration of clips in a Timeline panel.)

Click OK.
