A ripple edit trims the start or end of a clip and shifts everything after it so no gap is left, changing the total length of the sequence. Premiere Pro offers four trim tools: Ripple, Rolling, Slip and Slide. Each one adjusts a cut differently, so you can tighten pacing while keeping picture and sound in sync.
Why It Matters
A rough cut is rarely right the first time. If you fix a cut by dragging a clip edge and then repairing the gap or the overlap by hand, you risk pushing other clips out of place and breaking sync between picture and sound.
The four trim tools solve specific problems in one move: shorten a clip and close the gap, move a cut without changing length, change which part of a clip is shown, or reposition a clip between two neighbors. After you learn them, you spend less time fixing cuts. They build on the basics in timeline basics.
Beginner Using the Four Trim Tools to Tighten an Edit
Every clip on the timeline uses only part of its source file. The unused footage before the start and after the end is called handles. Trim tools work by moving the clip edges within those handles. You can only extend a clip as far as the handle allows.
Ripple edit (B)
The Ripple Edit tool trims one side of a cut and moves everything after it to close the gap, or to open it if you extend the clip. The sequence becomes shorter or longer. Use it to remove a pause, a stumble or the start of a clip you do not need.
Rolling edit (N)
The Rolling Edit tool moves the cut between two clips. One clip gets longer while the other gets shorter by the same amount, so the total length does not change. Use it to adjust exactly where one shot ends and the next begins.
Slip (Y)
The Slip tool changes which part of a clip is shown, without changing its position or length. Drag left or right on a clip and its In and Out points move together. Use it when the length is right but the action inside is a little early or late.
Slide (U)
The Slide tool moves a clip along the timeline while keeping its content and length. The clip before it gets longer or shorter and the clip after it does the opposite, so the sequence length stays the same. Use it to shift a cutaway to a better moment.
- Select the tool by pressing its key, or hold the Ripple Edit tool group in the toolbar to see all of them.
- Place the pointer over a cut or clip and drag. Watch the Program Monitor, which shows the frames on either side of the cut.
- Release when the cut feels right and play it back with Space.
- Press V to return to the Selection tool.
| Tool | Key | What changes | Sequence length |
|---|---|---|---|
| Ripple Edit | B | One clip edge, later clips shift | Changes |
| Rolling Edit | N | The cut between two clips | Same |
| Slip | Y | Content inside one clip | Same |
| Slide | U | Position of a clip among neighbors | Same |
Common Mistakes
- Using a ripple edit on one track while audio on other tracks is not sync-locked, which pulls them out of alignment.
- Trying to roll a cut when there is no handle left on one clip. The tool stops at the end of the source file.
- Choosing Slide when you meant Slip. Slide changes neighbors; Slip does not.
- Dragging with the Selection tool and leaving a gap, then forgetting to close it.
Advanced Choosing the Right Trim for Sync and Pacing, and Using Trim Mode
Which trim for which problem
Think about what must stay fixed. If the music or voice-over timeline is locked, use roll, slip or slide, which do not change total duration. If the cut itself is correct but the clip is too long, use a ripple edit. If the cut is in the wrong place between two shots, use a roll. If the pacing is right and the action is wrong, slip. If you need to move a cutaway to land on a beat or word, slide.
Trim mode
Double-click an edit point, or select it and use the Trim Edit command, to open trim mode. The Program Monitor changes to show the outgoing clip on the left and the incoming clip on the right, with buttons below each to nudge the cut by one or five frames. Dragging the edge in the timeline or using the buttons moves the cut while the monitor shows both sides. Playing in trim mode loops around the cut so you can judge rhythm repeatedly. Premiere also lets you toggle between ripple and rolling trims in this mode, and you can check the Keyboard Shortcuts dialog for the key assigned to that toggle in your version.
Trimming several edits at once
Shift-click several edit points, for example the video and audio cuts of a conversation, and then drag or nudge. They move together, which keeps parallel tracks aligned. Holding Alt (Windows) or Option (Mac) when you click a linked clip lets you trim only the video or only the audio, which is the basis of the split edit, also called a J-cut or L-cut. In a J-cut the audio of the next shot starts before its picture. In an L-cut the picture changes first while the previous audio continues. Both make dialogue edits feel smooth.
Ripple trim to the playhead
Move the playhead to where you want a clip to end, then press Q to ripple-trim the previous edit to the playhead, or W to ripple-trim the next edit to the playhead. This is the fastest way to delete dead time at the start or end of a clip, and it works the same on Windows and Mac. With the keys you learned in premiere shortcuts, you can tighten a rough cut without touching the mouse.
Sync lock and ripple behavior
A ripple edit shifts clips on every track whose Sync Lock is on. That keeps picture and music aligned, but it also means a ripple on V1 can move graphics or sound effects on other tracks. Turn Sync Lock off on tracks that should not move, such as a music bed. If a clip on another track crosses the edit point, Premiere may refuse the ripple or leave a gap, so check the message that appears.
Judging a cut
Dialogue cuts often feel best a few frames after the speaker finishes. Cuts on action feel natural when the movement starts in one shot and finishes in the next. Trim tools do not decide this; they let you test choices quickly. Trim by a few frames at a time, replay, and compare.
Try It
- Place three clips of a person talking or moving on V1 and play them.
- Press B and ripple-trim the start of the second clip to remove the first second. Notice the sequence getting shorter.
- Press N and roll the cut between clips two and three by about ten frames. Check that the total length did not change.
- Press Y and slip the middle clip until a gesture lands on the cut. Then press V.
- Play the whole sequence. Look for a jump, a gap or a sound that now starts too early.
Common Questions
What is the difference between ripple and rolling edit?
A ripple edit trims one clip edge and moves the later clips, so the sequence length changes. A rolling edit moves the cut between two clips, lengthening one and shortening the other, so the overall length stays the same.
When should I use the Slip tool?
Use Slip when a clip is the right length and in the right place, but a different part of the source would be better. Dragging changes the In and Out points together, leaving the clip position and duration alone.
Why can I not roll or slip a clip further?
You have run out of handle. Trim tools only reveal footage that already exists beyond the clip In and Out points. If the source file ends, the tool stops, so you need a longer clip or a different shot.
Do trim tools work on audio?
Yes. They work on any clip, and linked video and audio trim together unless you hold Alt on Windows or Option on Mac to select one part. That is how you make split edits such as J-cuts and L-cuts.
