View the total duration of selected clips
1. Make sure that the Info panel is visible. If it is not, choose Window > Info.
2. In either the Project panel or Timeline panel, select the clips for which you want to know the total duration. The Info panel displays the
number of items selected and the total duration of those items. This information is useful if you want to paste clips into a specific area and
need to know the exact duration of the target area or of the source clips.
Note: If you select contiguous clips in the Project panel, the Info panel displays the total duration of all the clips you select. However, if you
select noncontiguous clips in a sequence, the Info panel displays the duration as a range, from In point of the first clip you selected, to the
Out point of the last clip you selected. For the purpose of copying and pasting, the duration of a particular range is more important than the
sum of all the clips’ durations. If you copy and paste a noncontiguous group of sequence clips, the pasted clips will occupy the range noted
on the Info panel and the areas that you did not select will be empty.
Change the default duration for still images
1. Choose Edit > Preferences > General (Windows) or Premiere Pro > Preferences > General (Mac OS).
2. For Still Image Default Duration, specify the number of frames you want as a default duration for a still image.
Note: Changing the default duration of still images does not affect the duration of still images that are already part of a sequence or that
have already been imported. You will have to re-import the images after you change the default duration to get a different duration for the
images.
Change speed and duration for one or more clips
The speed of a clip is the playback rate compared to the rate at which it was recorded. Initially, a clip plays back at its normal, 100% speed. (Even
if the frame rate of the source footage doesn’t match that of the sequence, the sequence automatically reconciles the difference. It plays back the
clip at its proper speed.)
In a Timeline panel, clips with speed changes are indicated with a percentage of the original speed.
Changing clip speed omits or repeats the source frames during playback, thereby making the clip play faster or slower. A change in speed results
in a corresponding change in duration, unless the clip is simultaneously trimmed. You can, for example, ungang speed from duration in the Clip
Speed/Duration dialog box. Then, when you increase the speed, Premiere Pro uses more of the clip to fill the duration between the In point and
the Out point. When you decrease the speed, Premiere Pro uses less of the clip to fill the duration.
You can ungang speed and duration with more than one clip selected. Then, you can change the duration of the clips. For example, you can
change the speeds only enough to make all the clips last the same duration.
When you change the speed of a clip containing interlaced fields, you can adjust how Premiere Pro treats the fields. Consider making this
adjustment especially when the speed drops below 100% of the original speed. (See Create interlaced or non-interlaced clips.)
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.
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.
