iPhone video editing is built in — you don't need to download anything
Your iPhone comes with a video editor already installed. It's called Photos, and it lets you trim clips, adjust colors, add music, and arrange multiple videos into one sequence without leaving your phone. You open it the same way you open any app: tap Photos on your home screen, find the video you shot, and tap Edit.
The editing tools appear at the bottom of the screen once you tap Edit. You can cut out the beginning or end, slow down or speed up the footage, rotate it, add filters, adjust brightness and contrast, and layer in music or sound effects. Most edits take under five minutes. When you're done, you save the edited version back to your Photos library — the original stays untouched.
If you want more control than Photos offers, your iPhone also comes with iMovie, which is Apple's more powerful video editor. iMovie lets you arrange multiple clips in sequence, add transitions between them, include titles and credits, and layer in background music more precisely. It's free and works on any iPhone model from the last several years.
Key Takeaways
- Open any video in the Photos app, tap Edit, and use the tools at the bottom to trim, filter, adjust colors, or add music without downloading anything.
- The Photos app saves your edits as a new version of the video, leaving your original untouched in case you want to start over.
- iMovie, which comes free on your iPhone, lets you combine multiple videos, add transitions between clips, and include titles and background music.
- Edited videos take up storage space on your phone, so delete old versions or move finished videos to cloud storage if you're running low on space.
Trimming and cutting clips in Photos
Open the Photos app and find the video you want to edit. Tap the video to play it, then tap Edit in the top right corner. A timeline appears at the bottom showing your entire video as a series of frames. Two vertical handles (one on each end) mark the start and end points.
Drag the left handle to the right to cut out the beginning of the video. Drag the right handle to the left to cut out the end. As you drag, the preview at the top updates so you can see exactly where you're cutting. When the video shows only the part you want to keep, tap Save in the bottom right. Your phone asks whether to save as new video or replace the original — choose Save as New Video to keep both versions.
If you need to cut out a section from the middle of a video, Photos doesn't do that directly. You would need to use iMovie instead, which lets you split a clip and delete the unwanted section between the two pieces.
Adjusting colors, brightness, and adding filters
After you tap Edit on a video in Photos, look for the three overlapping circles icon at the bottom of the screen — that's the filter and adjustment tool. Tap it to see a row of preset filters (like Vivid, Warm, or Cool) that change the overall look of your video instantly. Swipe left or right through the filters and tap the one you like.
Below the filters, you'll see sliders for Exposure (brightness), Contrast, Saturation (color intensity), and Warmth (how yellow or blue the video looks). Drag each slider left to decrease the effect or right to increase it. The preview updates as you adjust, so you can see the changes in real time. Most videos benefit from a small boost to contrast and saturation — usually moving the slider a quarter of the way to the right.
If you make a mistake, tap the filter or slider again and drag it back to the middle (the neutral position). You can undo all adjustments by tapping the original filter name at the far left of the filter row.
Slowing down or speeding up video
Tap Edit on your video, then look for the speedometer icon at the bottom of the screen. Tap it to open the speed controls. A slider appears with options ranging from 0.5x (half speed, so the video plays twice as slow) to 2x (double speed, so it plays twice as fast).
Drag the slider to the right to speed up the video or to the left to slow it down. Slow motion works well for action shots — a jump, a catch, or someone running. Speed-up works for time-lapse footage or to cut down the length of a long, boring clip. The audio speeds up or slows down along with the video, so very slow videos sound strange. If you slow a video to 0.5x, the audio becomes hard to understand.
You can only change the speed of the entire video at once in Photos. If you want to speed up one section and slow down another, you need iMovie, which lets you adjust speed for individual clips.
Adding music and sound effects
Tap Edit on your video, then look for the musical note icon at the bottom. Tap it to open the music library. You'll see a list of songs from your iPhone's music library, plus a section called "Sounds" with built-in sound effects like applause, laughter, or notification chimes.
Tap any song or sound to preview it. If you like it, tap it again to add it to your video. The audio plays over your original video sound — both play together. If you want to remove the original sound (for example, if you're adding music and don't want to hear the background noise from when you filmed), tap the speaker icon with a line through it at the top of the music library.
In Photos, the music or sound effect plays for the entire length of your video. If your video is 30 seconds long and you add a 3-minute song, the song keeps playing even after the video ends — you won't hear that in the Photos app, but it will happen if someone watches the video on another device. To control exactly when music starts and stops, use iMovie instead.
Rotating and flipping video
If you filmed a video sideways by accident, or you want to flip it horizontally, tap Edit and look for the crop icon (it looks like two overlapping right angles) at the bottom of the screen. Tap it to open the rotation and crop tools.
You'll see four icons: a curved arrow pointing left (rotate counterclockwise), a curved arrow pointing right (rotate clockwise), a double-headed arrow (flip horizontally), and a crop box (adjust the frame). Tap the rotation arrows to turn the video 90 degrees at a time. Tap the flip arrow to mirror the video left-to-right. The preview updates instantly so you can see the result.
Cropping lets you zoom in and cut out the edges of the frame — useful if you filmed something off-center or want to remove distracting elements from the sides. Drag the corners of the crop box inward to frame the shot the way you want it.
Using iMovie for more complex edits
iMovie is the next step up when Photos isn't powerful enough. Open iMovie (it's on your home screen or in the App Library), tap the plus icon, and choose Movie. Select the videos and photos you want to include, then tap Create Movie. iMovie arranges them in a timeline at the bottom of the screen.
In iMovie, you can rearrange clips by dragging them left or right in the timeline. You can add transitions (like fades or dissolves) between clips by tapping between two clips and choosing a transition style. You can add titles at the beginning or between clips, and you can layer in background music that plays under all your clips at once.
iMovie also lets you adjust the speed of individual clips (not the whole video), add color correction to specific clips, and trim clips more precisely. The trade-off is that iMovie is more complex — it takes longer to learn and longer to edit. Use Photos for quick single-clip edits and iMovie when you're combining multiple clips or need fine control.
Saving and sharing your edited video
When you finish editing in Photos, tap Save in the bottom right. Your phone asks whether to save as new video or replace the original. Choose Save as New Video — this keeps your original untouched in case you want to edit it differently later. The new version appears in your Photos library with a timestamp showing when you saved it.
To share your video, open Photos, find the edited version, tap the share icon (it looks like a box with an arrow pointing out), and choose how you want to send it: text message, email, AirDrop to another Apple device, or social media. Your phone compresses the video for sharing, which makes the file smaller but may reduce quality slightly.
If you edited in iMovie, tap the share icon in the top right corner of the screen, choose where you want to save it (usually Photos), and iMovie exports the finished video. This also takes a few minutes depending on how long your video is and how powerful your iPhone is.
Frequently Asked Questions
Can I edit a video that someone else sent me?
Yes. Open the message or email containing the video, tap and hold it, and choose Save Video. It goes into your Photos library. From there, you can edit it the same way you would edit a video you filmed yourself.
What happens to the original video when I save my edits?
If you choose Save as New Video, the original stays in your Photos library untouched, and a second copy with your edits is created. If you choose Replace Original, the edited version overwrites the original and you can't get the unedited version back. Always choose Save as New Video unless you're certain you don't want the original.
Why does my edited video look blurry or pixelated?
Your iPhone compresses videos to save storage space. If you edited a low-resolution video or made major changes like extreme slow-motion, the quality may suffer. Filming in 4K instead of 1080p gives you more detail to work with, though it uses more storage.
Can I edit a video that's already been shared on social media?
Yes, but the quality may be lower because social media apps compress videos when you upload them. Download the video from the platform if possible, or ask the person who posted it for the original file. Editing a compressed version produces a lower-quality result.
How much storage space does an edited video use?
It depends on the length and resolution. A one-minute video filmed in 1080p uses roughly 100 to 150 megabytes. A one-minute 4K video uses 300 to 400 megabytes. If you're running low on storage, delete old edited versions you no longer need or move finished videos to cloud storage like iCloud or Google Drive.
