Edit video directly on your iPhone using the Photos app or iMovie

You can trim, rotate, and adjust color on any video already on your iPhone without downloading anything extra — the Photos app has these tools built in. For more control, like adding music, text, or transitions between clips, use iMovie, which is free from the App Store. Both work on any recent iPhone model running iOS 15 or later.

The Photos app is fastest for quick fixes: cutting out the beginning or end of a video, straightening a sideways recording, or brightening a dark clip. iMovie is better when you want to combine multiple videos, add a soundtrack, or make something that looks polished. Most people start with Photos and move to iMovie only when they need features Photos doesn't have.

Key Takeaways

  • The Photos app on your iPhone can trim videos, rotate them, and adjust brightness and color without installing anything.
  • iMovie, a free app from Apple, lets you combine multiple videos, add music and text, and explore transitions.
  • Editing in Photos takes seconds for straightforward cuts; iMovie projects take longer but give you more creative control.
  • Always save your edited video as a new file so you keep the original in case you want to start over.

Trim or cut a video in the Photos app

Open the Photos app and find the video you want to edit. Tap it to open it full screen, then tap Edit in the top right corner. You'll see a timeline at the bottom with yellow handles on each end — drag the left handle to the right to cut out the beginning, or drag the right handle to the left to cut out the end. The part you remove will turn gray so you can see what's being cut.

When you're happy with the trim, tap Save in the bottom right. Your iPhone will ask whether to save as new video or replace the original — choose Save as New Clip to keep both versions. The trimmed video saves to your Photos library in seconds.

Rotate, flip, or straighten a video

In the Photos app, open your video and tap Edit. Look for the crop and rotation icon (it looks like a square with arrows at the corners) in the toolbar at the bottom. Tap it to see rotation options. You can rotate 90 degrees left or right, or flip the video horizontally if it's mirrored.

If your video is tilted slightly, use the dial that appears to straighten it — drag the circle left or right until the horizon or your subject looks level. Tap Done when the angle is right, then tap Save and choose Save as New Clip.

Adjust brightness, color, and contrast

Open your video in Photos and tap Edit. Swipe left on the toolbar at the bottom until you see the adjustment sliders — they look like a sun icon, a circle with lines, and other symbols. Tap each one to adjust brightness, contrast, saturation, or warmth. Drag the slider left to decrease the effect or right to increase it. You'll see the changes on your video in real time.

Start with brightness if your video is too dark or washed out. Then adjust saturation if the colors look dull or oversaturated. Don't push any slider all the way — small changes usually look better than extreme ones. When you're done, tap Done and then Save as a new clip.

Combine videos and add music with iMovie

read iMovie from the App Store if you don't have it already — it's free. Open the app and tap the plus icon to start a new project, then choose Movie. Tap Create Movie. You'll see your photo and video library at the bottom. Tap each video you want to include, in order — they'll appear in a timeline at the top. You can rearrange them by dragging.

To add music, tap the plus icon at the top of the timeline, then tap Audio. Choose from iMovie's built-in soundtracks or tap My Music to use a song from your library. Drag the music to the timeline. The music will play under your entire video, and iMovie will automatically fade it out at the end.

Add text and transitions in iMovie

In your iMovie project, tap the plus icon and choose Text to add a title or caption. Select a text style, then tap the preview to type your words. The text will appear over your video for a few seconds — you can drag the text box in the timeline to move it to a different part of your video, or drag its edges to make it longer or shorter.

To add transitions between videos, tap the icon that looks like overlapping circles (between two clips in the timeline). Choose a transition style like Fade, Push, or Dissolve. Most transitions last about half a second — you can tap the transition to adjust its length. Don't use the same transition everywhere; one or two different types throughout a video looks more professional than using the same one every time.

Export and save your finished video

When you're done editing in iMovie, tap Done in the top left. Your project saves automatically. To save it as a video file you can share, tap the share icon (arrow pointing out of a box) and choose Save Video. Select the quality — High is best for sharing online, Medium saves space, and Low is only for quick previews. The export takes a few minutes depending on your video's length and your iPhone's speed.

Once it's done, the video saves to your Photos library. You can now share it through Messages, email, or social media. If you want to edit it again later, the iMovie project stays in the app — you don't have to start over from scratch.

Frequently Asked Questions

Can I undo changes after I save a video in Photos?

If you saved as a new clip, your original video is still there untouched. If you replaced the original, you can undo by opening the video, tapping Edit, and tapping Revert. This only works if you haven't closed the Photos app yet. After that, the original is gone — always save as new clip to be safe.

Why does my iMovie video look blurry when I export it?

Make sure you're exporting at High quality, not Medium or Low. If it's still blurry, your original video might be low resolution. iMovie can't improve a video that was recorded in low quality — it can only make it worse. Check that your iPhone's camera is set to record in 1080p or 4K in Settings > Camera > Record Video.

Can I edit a video that's already been shared or uploaded?

Yes, but you're editing a copy. Open it in Photos or iMovie and make your changes, then save it as a new file. The original version you shared stays the same everywhere it was posted. You'll need to re-upload the edited version if you want it to replace the old one.

How long can a video be in iMovie?

iMovie can handle videos as long as your iPhone's storage allows — there's no built-in limit. However, very long videos (over 30 minutes) may slow down your iPhone while editing. If your project is taking too long to load, try breaking it into smaller videos and editing them separately.
