Ripple edits
In this example of a ripple edit, the Out point of a
clip is moved two frames to the right in the timeline,
resulting in the duration of the clip being lengthened
by two frames. The adjacent clip is not altered by a
ripple edit; therefore, the overall program duration is
lengthened from eight frames to 10.
In this ripple edit, the Out point of a clip is moved
two frames to the left in the timeline, resulting in the
duration of the clip being shortened by two frames.
Because the adjacent clip is not altered by a ripple
edit, the overall program duration is shortened from
10 frames to eight.
Rolling edits
In this example of a rolling edit, the Out point of a
clip is moved two frames to the right in the timeline,
resulting in the duration of the clip being lengthened
by two frames. The rolling edit shortens the begin-
ning of the adjacent clip by two frames, thereby pre-
serving the duration of the overall program.
In this rolling edit, the Out point of a clip is moved two
frames to the left in the timeline resulting in the dura-
tion of the clip being shortened by two frames. The
rolling edit correspondingly lengthens the beginning
of the following clip by two frames, thereby preserv-
ing the duration of the overall program.
Slip edits
The slip edit moves the In and Out points of a clip, but
does not change the duration of the clip, does not
aect the adjacent clips, and does not alter the dura-
tion of the overall program.
You can slip the In and Out points of the clip to the
right or to the left on the timeline; neither the adja-
cent clips nor the overall program length are aected.
Slide edits
The slide edit moves the In and Out points of a clip
without changing its duration, while the Out and In
points of the adjacent clips are moved, so the overall
program duration is preserved.
You can slide the In and Out points of the clip to the
right or to the left on the timeline; the overall pro-
gram length is maintained because the Out and In
points of the adjacent clips slide accordingly.
Making transitions
Transitions are the methods you use to get from one clip to the next. e basic transition is a cut.
Slower transitions can be useful in setting a mood or adding a creative element to your project.
Examples of transitions include dissolves, wipes, zooms, and page peels. Adobe Premiere Pro
includes a whole library of transitions, and you can add others, such as QuickTime transitions.
You’ll nd transitions in the Video Transitions bin in the Eects panel. Within this bin, transi-
tions are organized into nested bins by type. You can customize these groupings, putting the
transitions you prefer into bins you name, or by hiding transitions that you don’t oen use.
To add a transition, drag the icon from the Eects panel to a point in the timeline where two
clips meet. Alternatively, you can specify a default transition, and automate the process of adding
transitions. You can use the Eect Controls panel to apply, remove, or adjust the settings of a
transition at any time.
USEFUL EDITING TECHNIQUES
Changing clip speed: Clip speed is the playback
rate of action or audio compared to the rate at which
it was recorded. When the speed is accelerated,
everything appears to move faster; when the speed is
reduced, the action or audio plays back in slow
motion. Changing a clip’s speed alters its source
frame rate. Some frames may be omitted when the
speed is increased; when the speed is decreased,
frames may be repeated. Changing the speed to a
negative value, such as -100, plays the clip in reverse.
You can change a clip’s speed numerically in the
Project panel, or in the timeline by choosing Clip >
Speed/Duration from the title bar. You can change
speed visually in the Timeline panel by using the rate
stretch tool to drag either end of the clip. A three-
point edit can also change the speed of a clip.
Altering clip duration: The duration of a clip is the
length of time it plays: from its In point to its Out
point. The initial duration of a clip is the same as it
was when the clip was captured or imported; if you
alter the source In and Out points, the duration of
the clip changes. In Adobe Premiere Pro, you can edit
In and Out points in the Project panel, the Source
Monitor, or directly in the timeline. You can change
duration numerically in the Project panel or in the
Timeline panel by choosing Clip > Speed/Duration
from the title bar. You can change duration visually in
the Timeline panel by dragging either end of the clip
with the selection tool.
It’s important to note that when you perform any
action that extends the duration of a clip (which may
include ripple or rolling edits) additional frames must
be available in the source clip (the clip you originally
captured or imported) before the current In point
or after the current Out point. This is why it’s a good
practice, whenever possible, to capture extra mate-
rial, sometimes referred to as a handle.
Ripple edit: A ripple edit changes the duration of a
clip, correspondingly changing the duration of the
entire program. When you use the ripple edit tool to
shorten or lengthen a clip by dragging its begin-
ning or ending in the timeline, the adjacent clip is
not aected and, consequently, the duration of the
program is shortened or lengthened.
Rolling edit: A rolling edit changes the duration of
the selected clip and of an adjacent clip, while main-
taining the overall duration of the program. When
you use the rolling edit tool to shorten or lengthen a
clip by dragging its beginning or ending in the Time-
line, the adjacent clip is correspondingly lengthened
or shortened.
