Adding J-cuts and L-cuts: Lesson 11-3


Frequently you'll want to start a video clip by having its sound play under the previous video clip and then transition to its associated video. This is a great way to let your audience know that someone is about to say something or that a transition is coming. This is called a J-cut, so named because it looks vaguely like a 'J' on the sequence.

Conversely, another slick editing technique is to let audio tail off under the next video clip. This is an L-cut.

To do either of these cuts requires that you unlink the audio and video portions of a linked A/V clip so you can edit them separately. After they've been unlinked, you can move that audio segment to another audio track and then extend or shorten the audio portion to make the J- or L-cut. There are two unlinking methodsa right-click context menu and a keyboard modifier. I'll show you both.


1.

Open the Lesson 8.


Note

In this case the cutaway clips aren't being used as cutaways. They're B-rollbasic video used to piece together a project.

The cutaway

video plays over the first few words of the sound bite

audio and then the cutaway

video dissolves to the interview clip while the cutaway

audio fades outa J-cut. That process is reversed for the end of the sound bitean L-cut.


2.

Open the Lesson 11-3 Start sequence.

3.

Right-click the second clip and select Unlink.


4.

Complete the Unlink process by clicking outside that clip in the Timeline to deselect it.

Now when you click on either the audio or video portion of that clip, only that portion is selected. You'll re-link these clips, then use a keyboard modifier to temporarily unlink them.

5.

Shift+click on both of those unlinked clips to select them (if one is already highlighted, there's no need to Shift+click on it).

6.

Right-click on one of them and select Link.

Now you'll use the keyboard modifier unlinking method.

7.

Alt+click on the audio portion of the second clip. That unlinks it and selects it.

8.

Drag that unlinked audio portion of the second clip straight down to the Audio 2 track.


Note

As you move the audio portions of your clips in the sequence, take care that you don't slide them left or right when you drag them. Otherwise the audio and video will get out of synch. Premiere Pro gives you a visual cue to help you line up your clips: if you see a black line with a triangle, your clips are properly lined up. If that black line disappears, you have moved out of synch. In that case, move the clip around a bit until the black line reappears.


9.

Using the Lesson 8, letting the interviewee get off screen before cutting to the interview video makes for a more comfortable shift.

10.

Drag the left edge of the audio portion of the second clip to the left to give you some room to fade it up (it has a few header frames).

11.

Apply four keyframes on the clips in the Timeline (use the following figure as a guide):

  • First audio clip You will fade the audio at the end of the clip down just before the rider in the second clip (Sound Bite 8a) starts talking. To do that, place a keyframe at that point (use the beginning of the waveform in the second clip to find that spot) and place another keyframe at the end of the clip. Drag the end keyframe all the way down to fade the cutaway audio out.

  • Second audio clip At the beginning of the clip and just as the rider starts talking. Drag the beginning keyframe all the way down to have that sound bite audio fade up.



12.

Play that J-cut. The cutaway's natural sound should fade as the rider begins speaking.

13.

Drag a Cross Dissolve video transition to the edit point between the two video clips to make this work even more smoothly.



Adding an L-cut


Now that you've unlinked the center clip, adding an L-cut at the end of this segment will take only a few steps.


1.

Move the Timeline CTI to just after the rider says "thumbs up"about 12;21.

2.

Drag the entire third clip (not the left side but the whole clip) to the left until the Snap feature causes its first frame to line up with the CTI.

This cutaway clip will cover up (overlay) the video portion of the rider's last few words but that final interview audio snippet will play along with the audio of the cutaway.


3.

Add six keyframes as follows (use the next figure as a guide):

  • Second audio clip Put one keyframe directly after the rider says "important stuff" and another one at the end of the clip. Drag the end keyframe all the way down to fade that sound bite audio under the cutaway.

  • Third audio clip At the start, a half-second or so into the clip, a half-second or so before the rider says "important stuff" (on the other audio clip) and directly after the rider finishes talking. Drag the first keyframe all the way down, move the second and third to about 9 dB (to play the cutaway audio quietly

    under the sound bite), and the fourth to full volume or 0 dB (move the volume graph to the center of the clip (its default position), between the right and left channels).



4.

Add a video Cross Dissolve between the video portions of these two clips.

5.

Play that L-cut.

The closing cutaway's natural sound should fade up quietly beneath the rider's closing comment, then climb to full volume at the end.
