You're sitting there with a massive, unwieldy chunk of video footage. Maybe it's a ten-minute recording of your cat doing something mildly interesting for exactly three seconds, or perhaps it’s a professional interview where the subject spent the first five minutes coughing and adjusting their tie. You need it gone. Now. The big question is simple: how do you cut a clip in iMovie so it actually looks like a real movie and not a jagged mess of accidental clicks?
It's honestly one of those things that feels intuitive until you're actually staring at the timeline. Apple loves to hide things in plain sight. You’d think there’d be a giant "SCISSORS" button right in the middle of the screen, but instead, we’re left hunting through menus or memorizing keyboard shortcuts that feel like playing a game of Twister with your fingers.
The Split Command is Your Best Friend
Most people think they need to "cut" a clip like they’re using physical film, but in the digital world of iMovie, you're usually "splitting." Splitting is the foundation. It’s the bread and butter of editing.

To do this, you have to move that vertical white line—the playhead—to the exact millisecond where the action starts or ends. If you're on a Mac, you just hit Command + B. Boom. One clip becomes two. It’s satisfying. It’s clean. You can then click the part you don’t want and hit the delete key. Suddenly, your video is lean.
If you’re working on an iPhone or iPad, the process is slightly more tactile. You tap the clip in the timeline so it gets that thick yellow border around it. Then, you swipe down on the playhead. It’s like a slicing motion. iMovie treats your finger like a blade, which is honestly kind of cool when it works on the first try. If it doesn't, you just tap the "Modify" button at the bottom and select "Split."
Precision Trimming vs. The Chainsaw Approach
Sometimes you don't want to split the whole thing; you just want to shave off a few frames from the beginning or the end. This is called trimming.
Basically, you grab the edge of the clip—the yellow handle—and drag it inward. If you drag it too far, don't panic. The footage isn't "gone" forever; it’s just hidden. iMovie is a non-destructive editor, which is a fancy way of saying it’s very hard to truly break your original file. You can always drag that handle back out to recover what you cut.
But here’s where people get frustrated. They try to trim a clip that is already as short as it can go, or they try to drag a clip into a space where there isn't enough room. If the yellow handle turns red, you’ve hit the end of the line. There’s no more video left in that file to show.
The "Secret" Precision Editor
If you’re struggling to get a cut exactly on the beat of a song or the blink of an eye, the standard timeline view is your enemy. It’s too small. You need the Precision Editor.
You can open this by double-clicking the edge of a clip where it meets another. The view changes entirely. Now, you see the "outgoing" clip and the "incoming" clip stacked on top of each other. This lets you see exactly how much overlap you have. You can slide the cut point left or right until the transition feels natural.
Professional editors at places like EditMentors or Inside the Edit often talk about "cutting on action." This means if someone is sitting down, you cut right as their butt hits the chair. The Precision Editor is the only way to nail that in iMovie without losing your patience.
Why Your Cuts Might Look "Jumpy"
We’ve all seen it: a video where the person's head suddenly snaps two inches to the left. This is a "jump cut." Sometimes it's a stylistic choice (think YouTube vlogs from 2012), but usually, it’s just a mistake.
When you figure out how do you cut a clip in iMovie, you also have to figure out how to hide the evidence. Transitions are the obvious answer, but please, for the love of cinematography, stay away from the "Cube" or "Page Peel" transitions unless you're making a video for a third-grade class project. A simple "Cross Dissolve" is usually plenty.
Better yet? Use a B-roll clip. If you have a jump cut in an interview, drop a 2-second shot of the person's hands or a shot of what they’re talking about right over the cut. It masks the jump and makes you look like a pro.
Managing the Ripple Effect
One thing that trips up beginners is how iMovie moves everything else when you make a cut. This is called a "Magnetic Timeline."
When you delete a three-second chunk from the middle of your project, iMovie automatically pulls everything on the right side over to fill the gap. This is great because it prevents accidental black screens. It’s terrible if you’ve perfectly timed a background music track or a title card to a specific moment later in the video, because now everything is out of sync.
To fix this, you have to be mindful of "connected clips." Those are the little photos or titles sitting on top of your main video. They are literally tethered to a specific spot on the main timeline. If you cut the clip they are attached to, they might move—or disappear—along with it.
Dealing with Audio While Cutting
Cutting video is easy. Cutting audio is a nightmare.

If you cut a clip right in the middle of someone saying the word "Apple," you're going to hear a weird "Ap—" and then a click. It sounds terrible.
The trick is to "Detach Audio." Right-click your clip (or tap the audio icon on mobile) and select "Detach Audio." Now the sound is a separate green bar below the video. You can cut the video at one spot and let the audio continue for a few frames longer. This is called an L-cut or a J-cut. It’s what makes professional movies feel smooth. The sound of the next scene starts before you actually see the picture.
Common iMovie Glitches and How to Dodge Them
Let's be real: iMovie can be buggy. Sometimes you try to split a clip and the option is grayed out. Why? Usually, it's because you haven't actually selected the clip. It sounds dumb, but it happens to the best of us. Click the clip until it's yellow.
Other times, iMovie won't let you cut because you're in the middle of a "Ken Burns" animation or some other effect. Finish your effects first, or better yet, do your big cuts before you start adding the fancy stuff.
Also, watch your storage. iMovie creates massive cache files. If your Mac starts crawling while you're trying to edit, it might be because you're out of disk space. iMovie needs "breathing room" to render those cuts in real-time.
Mastering the Keyboard for Faster Editing
If you want to get through a two-hour wedding video without it taking two weeks, you have to stop using the mouse for everything.
- Spacebar: Play and pause. (You knew this one).
- Command + B: The holy grail of splitting.
- Command + Z: The "oh no I messed up" button (Undo).
- Left/Right Arrows: Move frame by frame. This is how you get that perfect cut.
- Backslash (): Play from the playhead.
Mobile Specifics: The "Short" Way
Editing on an iPhone is a different beast. You don't have a keyboard. You have fat fingers.
The best way to cut on mobile isn't actually splitting; it's using the "yellow handles" to scrub the video. But if you have a huge file, scrubbing is imprecise. Instead, use the pinch-to-zoom gesture on the timeline. Zoom in until you can see the individual seconds. Only then should you try to make your cut.
If you accidentally delete a clip on mobile, there’s a curved "undo" arrow on the right side of the screen. Tap it immediately. Unlike the Mac version, the mobile version feels a bit more "permanent" once you navigate away from a project.
Actionable Next Steps for Better Editing
Knowing how do you cut a clip in iMovie is just the start. To actually finish a project you're proud of, follow this workflow:
- The Rough Cut: Go through your whole timeline and use Command + B to chop out all the "junk"—the coughs, the dead air, the blurry shots. Don't worry about transitions yet. Just get the story down to its essence.
- The Refinement: Use the Precision Editor to clean up the joins between the clips you kept. Make sure the pacing feels right. If a scene feels too long, it probably is. Cut another 10%.
- Audio Detailing: Detach the audio for important clips. Fade the music out at the end so it doesn't just stop abruptly. iMovie has little circles at the ends of audio clips—drag them to create a fade.
- Final Polish: Add your titles and transitions last. If you add them too early, every time you make a cut, you'll have to move them again.
Start by taking a single thirty-second clip and try to cut it down to exactly seven seconds of the most high-energy action. Once you can do that in under a minute, you've officially mastered the basic cut.

Summary of Shortcuts and Slices
When you're in the thick of it, remember that splitting is the most powerful tool you have. Whether you're using the Mac's Command + B or the iPhone's downward swipe, the goal is the same: isolation. Isolate the good, kill the bad, and keep the playhead moving. Editing is essentially the art of throwing away the parts of a video that aren't interesting. The more you "throw away," the better your final video becomes. Just keep an eye on your timeline sync, use the Precision Editor for the tricky spots, and always, always keep a backup of your original raw footage just in case you get a little too "cut-happy" with the delete key.
