The basic workflow: import, arrange, trim, export

iMovie is built around four straightforward steps: bring your video into the program, arrange your clips in order on a timeline, cut out the parts you don't want, and save the finished video. You don't need to learn every button — most editing happens by dragging clips around and clicking trim handles. The program runs on Mac computers and iPad, and the workflow is nearly identical on both.

The first time you open iMovie, you'll see a blank project. Click the camera icon or "Import Media" to bring in video files from your computer or phone. iMovie accepts MP4, MOV, and most common video formats. Once your clips are imported, they sit in a library on the left side of the screen. From there, you drag them onto the timeline at the bottom — that's where you arrange them in the order you want them to play.

Key Takeaways

  • Import your video files by clicking the camera icon, then drag clips from the library onto the timeline to arrange them in order.
  • Trim unwanted sections by clicking the yellow trim handles at the edges of each clip and dragging them inward.
  • Add transitions between clips by dragging them from the Transitions panel, and adjust their length by double-clicking the transition itself.
  • Export your finished video by clicking File, then Share, then File, and choose a resolution that matches where you plan to watch it.
  • iMovie saves your project automatically, so you can close the program and return to the same edit later without losing work.

Importing video and organizing clips on the timeline

Click the camera icon in the top left corner of iMovie. A window opens showing your computer's folders and any connected devices. Navigate to the folder where your video files live, select the ones you want, and click Import. iMovie copies them into its library — this takes a few seconds per minute of video, depending on your computer's speed.

Once imported, your clips appear as thumbnails in the library panel on the left. To add a clip to your project, drag it onto the timeline at the bottom. The timeline shows your clips in the order they'll play. If you drag a clip between two existing clips, iMovie shifts everything to the right to make room. If you want to rearrange clips, drag them left or right on the timeline. To remove a clip entirely, click it on the timeline and press Delete.

iMovie also lets you use only part of a clip. If you drag a clip onto the timeline and later decide you want to cut it in half, double-click the clip on the timeline. A preview window opens showing the full clip. Drag the playhead (the vertical line) to the spot where you want to split it, then click the scissors icon. The clip breaks into two pieces on the timeline, and you can delete whichever one you don't need.

Trimming clips to remove unwanted footage

Every clip on your timeline has yellow handles at its left and right edges. These are trim handles. To remove footage from the beginning of a clip, hover over the left handle until your cursor changes to a resize arrow, then drag it to the right. To remove footage from the end, drag the right handle to the left. As you drag, iMovie shows you a preview of where you're cutting, so you can see exactly what stays and what goes.

If you need to be more precise, double-click the clip to open the preview window. Use the playhead to find the exact frame where you want to cut, then click the scissors icon. This splits the clip at that exact spot. You can then delete the unwanted section by clicking it and pressing Delete. This method is slower but gives you frame-by-frame control.

A common mistake is trimming too aggressively. If you cut a clip and realize you removed too much, undo the action by pressing Command-Z (on Mac) or Ctrl-Z (on iPad with a keyboard). You can undo multiple steps this way, back to the point where the clip was whole again.

Adding transitions and adjusting their timing

A transition is a visual effect that plays between two clips — a fade to black, a slide, a dissolve. To add one, click the Transitions button in the toolbar (it looks like two overlapping squares). A panel opens showing available transitions. Drag a transition onto the space between two clips on your timeline. iMovie automatically places it there and applies a default length, usually half a second.

To change how long a transition lasts, double-click it on the timeline. A small window appears with a slider. Drag the slider left to make the transition faster, or right to make it slower. Most transitions look natural between 0.5 and 1.5 seconds. Anything longer usually feels sluggish. Click outside the window to close it and explore the change.

You can also add transitions to the very beginning or end of your video. Drag a transition onto the first clip (before any other clips), and iMovie will explore it as an opening effect. Drag one onto the last clip, and it becomes an ending effect. These are less common but useful if you want your video to fade in from black at the start or fade to black at the end.

Adding titles, music, and sound effects

Click the Titles button in the toolbar to add text overlays. A panel shows preset title styles — straightforward text, animated text, text with backgrounds. Drag a title style onto your timeline, either above a clip or between clips. Double-click the title on the timeline to edit the text. Type what you want to say, then click outside the text box to finish. You can adjust the title's length by dragging its edges on the timeline, just like a clip.

To add music or sound effects, click the Audio button in the toolbar. iMovie includes a library of royalty-free music and sound effects. Browse by category, click the one you want, and drag it onto your timeline below your video clips. The audio track plays alongside your video. If the music is too loud or too quiet, click it on the timeline and drag the volume slider that appears. You can also fade audio in or out by dragging the small handles at the edges of the audio clip.

If you want to use your own music file, click the camera icon and navigate to the audio file on your computer. iMovie treats it the same way — drag it onto the timeline and adjust the volume as needed. Keep in mind that if you use copyrighted music, you may not be able to share the video on YouTube or other platforms without a copyright claim.

Adjusting video speed and explore color correction

To slow down or speed up a clip, right-click it on the timeline and select "Retime" (on Mac) or tap and hold, then "Speed" (on iPad). A menu appears with preset speeds: 0.5x (half speed), 1x (normal), 2x (double speed), and custom. Choose one or enter your own number. The clip stretches or compresses on the timeline to match the new speed. Slow-motion clips are useful for dramatic moments; fast-motion works well for time-lapses or montages.

iMovie also includes basic color correction. Click a clip on the timeline, then click the color wheel icon in the toolbar. A panel opens with sliders for exposure (brightness), saturation (color intensity), and temperature (warm or cool tones). Drag the sliders to adjust the look of the clip. These changes explore only to that one clip, so you can make each clip look consistent even if they were shot under different lighting.

If all your clips look too dark or too bright, you can explore the same correction to multiple clips at once. Click the first clip, adjust the color sliders, then click the next clip while holding Shift. iMovie applies the same color settings to all selected clips. This is faster than correcting each one individually.

Exporting your finished video

Once your edit is complete, save it by clicking File in the menu, then Share, then File. A window opens asking where you want to save the video and what resolution you want. The resolution options are 1080p (standard quality, smaller file size), 4K (high quality, larger file size), and a few others. For videos you plan to watch on a phone or share on social media, 1080p is fine and saves storage space. If you shot in 4K or plan to watch on a large screen, choose 4K.

iMovie also lets you export directly to YouTube, Vimeo, or other platforms. Click File, then Share, then the platform you want. Sign in with your account, add a title and description, and iMovie uploads the video for you. This is faster than exporting to your computer first and then uploading separately.

Before you export, iMovie automatically saves your project. You can close the program and come back to the same edit weeks later — all your clips, transitions, and adjustments will still be there. Your project file is separate from the exported video, so you can make changes and export again without losing the original.

Frequently Asked Questions

Can I edit video on my iPhone or iPad?

Yes. iMovie on iPad works almost identically to iMovie on Mac, with the same import, timeline, and export steps. On iPhone, iMovie is more limited — you can edit but the smaller screen makes it harder to see details. If you're serious about editing, iPad or Mac is better. You can start a project on one device and finish it on another; iMovie syncs your projects through iCloud.

What video formats does iMovie accept?

iMovie works with MP4, MOV, M4V, and most common video files. If you have an older or unusual format, you may need to convert it first using a free tool like HandBrake. Most phones and cameras save video in MP4 or MOV, so you usually won't have this problem.

How do I remove audio from a clip?

Click the clip on the timeline, then right-click and select "Detach Audio" (Mac) or tap and hold, then "Detach Audio" (iPad). The audio separates from the video and appears as a separate track below. You can then delete the audio track, mute it, or keep it and add new audio on top.

Can I undo changes after I export the video?

Yes, because your project file is separate from the exported video. Even after you export, your project stays open in iMovie with all your edits intact. You can make changes and export again. The original exported video file doesn't change — you're creating a new one.

Why is my exported video blurry or low quality?

This usually means you exported at a lower resolution than your original footage, or your computer is struggling to process the export. Try exporting again at 1080p or 4K depending on your original video quality. If iMovie is running slowly, close other programs to free up memory, then try exporting again.
