To crop in iMovie on a Mac, select the clip in the timeline, click the Cropping button above the viewer and choose Crop to Fill. Drag and resize the frame in the viewer to frame the shot you want, then click Apply. In the timeline, the crop frame is locked to a 16:9 shape.
Cropping lets you zoom in on the part of a shot that matters: your face instead of the cluttered office behind you, the product rather than the table, the speaker rather than the whole stage. iMovie on a Mac makes it quick, with one limitation that catches out anyone hoping to make vertical video.
How to crop a clip in iMovie, step by step
- Select the clip or photo in the timeline.
- Click the Cropping button above the viewer.
- Click Crop to Fill. A frame appears over the clip in the viewer.
- Drag the frame to move it, and drag its corners to resize it.
- Click the Apply button in the cropping controls.
The cropped area now fills the screen. If you change your mind, select the clip again, open the cropping controls and click Reset.
The three cropping options
| Button | What it does | When to use it |
|---|---|---|
| Fit | Shows the whole clip, with black bars if the shape doesn't match | Restoring an old 4:3 clip to its original frame |
| Crop to Fill | Crops the clip to fill the frame, with a movable frame | Zooming in on a subject |
| Ken Burns | Moves between two crop positions to create motion | Adding movement to photos |
Crop before you add a clip to your movie
You can also crop a clip in the browser before it goes into your movie. Select it in the browser, click Cropping, click Crop, adjust the frame and click Apply. Apple notes that if you crop in the browser and later reset the crop in the timeline, the browser crop resets too.
The catch: you can't crop to vertical in the timeline
This is the limitation most people hit. Apple's guide says the Crop to Fill frame in the timeline is constrained to a 16:9 aspect ratio, which is the widescreen shape of a normal iMovie project. So you can crop in to a closer shot, but you can't crop a horizontal video into a tall 9:16 shape for Reels or TikTok.
If you need vertical video, either film vertically in the first place and edit in an app built for vertical formats, or export your iMovie project and reframe it in a tool that supports 9:16 projects. Trying to force iMovie into vertical usually ends in black bars.
Why old videos look stretched or cut off
If you mix older footage with newer HD clips, you might notice the edges of old videos are missing. Apple explains that when you add 4:3 standard-definition video to a 16:9 HD project, iMovie automatically crops it to fill the frame. To see the whole original picture, select the clip, open the cropping controls and click Fit. You'll get black bars down the sides, but nothing is cut off.
Cropping and video quality
Cropping zooms in, and zooming in on a video makes it softer. Crop a small area out of an HD clip and it can look blurry once it fills the screen. If you plan to crop a lot, film in the highest resolution your camera allows. Bear in mind your project's resolution is set by the first clip you add, so start with a high-resolution clip if you want a high-resolution export.
Crop a video in iMovie on iPhone
On an iPhone or iPad, select the clip in the timeline and pinch to zoom in on the viewer to crop. It's quicker but less precise than the Mac's crop frame, and the same horizontal project shape applies.
Tips for clean crops
- Crop each clip in a scene by the same amount so the look stays consistent.
- Leave a little space above people's heads rather than cutting them off at the forehead.
- Use Ken Burns on photos to add gentle movement instead of a static crop.
- Press Shift-F to jump back to the original source clip in the browser if you need to compare.
Crop or reshoot?
Cropping is a rescue tool, not a plan. If you find yourself cropping every clip heavily, it's a sign the camera is too far away. Next time, move the camera closer or zoom in before recording, and you'll get a sharper picture with no editing needed. I'd keep crops for the odd shot where something distracting crept into the edge of the frame, or where you want a tighter close-up for variety.

My verdict
Select the clip, click Cropping, choose Crop to Fill, frame it and click Apply. That covers most everyday crops. Just know that the timeline crop is locked to 16:9, so iMovie isn't the tool for turning horizontal footage into vertical Reels. For the clips you're editing, my guide to making effective short videos has tips on framing, and if you're recording testimonials, my roundup of testimonial video production companies shows what good looks like.
