Find a sharper frame in a Live Photo or Burst

Updated 13 October 2026 · UnBlur AI guides · 5 sources

AI results are estimates. AI restoration predicts what a sharper or repaired photo might look like. It can invent or change details, especially faces, text and fine patterns. Always keep your original, and do not use an AI-restored image as evidence or to identify someone.

Key points

A Live Photo records what happens 1.5 seconds before and after you take the picture, so a steadier moment may already be saved. ¹
To use another frame: open the Live Photo, tap Edit, tap the Live Photo button, move the white frame and tap Make Key Photo. ²
For a Burst, tap the thumbnail, tap Burst (number), choose frames with the circles and tap Done; gray dots mark suggested frames. ³
Judge sharpness at full zoom on the most important detail, usually the eyes, and compare several frames before deciding.

If a photo on your iPhone came out blurry, check whether it is a Live Photo or part of a Burst before you try any editing. Both features save more than one moment, and often one of the other frames is noticeably sharper. Swapping to that frame is free, takes a minute and uses real pixels from your camera instead of a guess. This guide shows how to do it with the built-in Photos app.

Why another frame can be sharper

Blur from camera shake or a moving subject changes from moment to moment. A hand tremor, a child turning a head or a dog shaking itself may smear one instant while the next is still. With Live Photos turned on, the iPhone records what happens 1.5 seconds before and after you take the picture ¹, and Burst mode captures photos in rapid succession for as long as you hold ³. Missed focus is different: if the camera focused on the background, every frame from that moment is usually soft in the same way. The guide to motion blur vs focus blur helps you tell which one you have.

Change the key photo of a Live Photo

The key photo is the still image that appears in your library. Apple's steps to choose another frame are ²:

Open the Photos app and open the Live Photo.
Tap the Edit button, then tap the Live Photo button.
Move the white frame along the frame viewer to the moment you want.
Tap Make Key Photo, then tap Done.

The same screen lets you trim the Live Photo, mute it, or turn off Live so it becomes a still of its key photo ². Apple notes one catch: Live Photos taken on an iPhone 15 model or later with a portrait effect lose that effect if you change the key photo ². If you change your mind, you can revert edits to go back to the original ⁴.

Pick the sharp frames from a Burst

Open the Burst in Photos: tap the Burst thumbnail, then tap Burst (number).
Swipe through the frames. Gray dots below the thumbnails mark the photos the iPhone suggests keeping.
Tap the circle in the lower-right corner of each photo you want to save as an individual photo, then tap Done ³.

The suggestions are a good starting point, but they are not always the sharpest frame for what matters to you, such as a particular face. Check a few frames yourself before you delete the rest of the Burst.

How to judge which frame is sharpest

Zoom in on what matters. Pinch to zoom on the eyes in a portrait, the ball in a sports shot, or the text on a sign. Sharpness at full size is what counts, not on the thumbnail.
Look for doubled edges. Thin lines that appear twice, or streaks in one direction, mean motion during the exposure.
Check fine texture. Eyelashes, hair, fabric weave and brick lines show softness first.
Compare the same spot. Switch between two candidate frames while zoomed in on the same detail; the difference is easier to see side by side than from memory.
Accept a trade-off. The sharpest frame may have closed eyes or a less natural expression. Sometimes a slightly softer frame with the right moment is the keeper.

Make your next Live Photos and Bursts more useful

Leave Live Photo on for moments with people and pets; it gives you a few seconds of alternatives at no extra effort ¹.
Use Burst for anything fast. You can turn on Use Volume Up for Burst in Settings, then Camera, and hold the volume up button to shoot ³.
Hold still for a moment after you press the shutter, because a Live Photo keeps recording after the shot ¹.
Lock focus on the subject first (touch and hold for AE/AF Lock) so every frame is focused on the right thing ⁵. More habits are in iPhone camera settings for sharp photos.

If no frame is sharp enough

When every frame is soft, try the free tools in the Photos editor: a small amount of Sharpness or Definition can make a mildly soft photo look crisper (see how to unblur a photo on iPhone and how to enhance photo quality on iPhone). Pick the least blurry frame as your starting point either way, because every later step works better on it.

An AI tool such as UnBlur can then predict a sharper version of that frame. Its result is an estimate: it can change small details such as eyes, teeth or text, so compare it with the original before you save it, and keep the original. For faces in particular, read how to fix a blurry face in a photo first.

Common questions

How many extra moments does a Live Photo keep?

A Live Photo records what happens 1.5 seconds before and after you take the picture, so you have about three seconds of alternatives to choose a key photo from. ¹

Can I change the key photo back later?

Yes. You can open the Live Photo in Edit again and choose a different frame, or revert the photo to its original from the editing tools. ^2,4

Should I delete the rest of a Burst?

Only after you have zoomed in and compared the frames you care about. Once you keep the individual photos you want, the remaining Burst frames are optional. ³
