The short answer is that an iPhone can't reverse a video on its own. The Photos app has no reverse button, and neither does iMovie for iPhone. You need another app, a Live Photo trick, or a Mac. This page covers each, and the two things that separate a good reverse from a bad one: what happens to the sound, and how long the clip is.
The fast answer
- It's a Live Photo: use the Bounce effect in Photos. Free, built in, three seconds long, forward then backward.
- It's a normal video and you're on the phone: use an app with a real reverse tool. Several are free; check for watermarks before you rely on one.
- You have a Mac: iMovie for Mac reverses a clip with a checkbox.
- The clip is long: trim it first. Reversing is slow in proportion to length, on every tool.
Why Photos can't just play it backwards
It seems like it should be easy. It isn't, and the reason explains why some apps are slow and some cut corners.
iPhone video (H.264 or HEVC) doesn't store every frame as a picture. It stores an occasional full frame, then a long run of frames that only describe what changed since the previous one. Playing forwards, that's cheap. Playing backwards, every frame depends on frames you haven't decoded yet, so the only honest way to reverse a clip is to decode it in chunks, reorder the frames, and encode the whole thing again as a new video.
That's a real render, not a playback trick, which is why Apple's lightweight editors don't offer it, and why reversing a five-minute clip takes noticeably longer than trimming one.
Route 1: Live Photo Bounce
If the moment you want reversed was taken as a Live Photo, this costs nothing.
- Open the Live Photo in Photos.
- Tap the Live button at the top left.
- Choose Bounce.
It plays forward and then backward in a loop. To get a video file out, tap the ⋯ button and choose Save as Video.
Where it breaks: it only exists for Live Photos, which are about three seconds long, and it's always forward-then-back. You can't get a clip that only plays in reverse, and you can't do it to anything you filmed as video.
Route 2: an app with a reverse tool
This is the route for any normal video on the phone. Plenty of App Store editors have a reverse option. Before choosing one, three questions matter more than the feature list:
- Does the free version watermark the export? Many do, or insert an end card, or limit the clip length. Find out before you spend ten minutes on an edit.
- Is the audio reversed, removed, or left playing forward? Some apps only reverse the picture. A reversed picture with forward sound is out of sync with everything on screen. See below.
- Does it upload the video? Some editors process on a server. For a family video that may not matter to you. It's still worth knowing.
The full editors such as CapCut and InShot both include reverse, alongside a great deal else, with the account prompts and upsells that come with an app of that size. If reverse, trim, crop and speed are all you need, a smaller tool does it with less in the way.
Frame-accurate reverse with the audio reversed too, stacked with trim, crop, flip and speed in one export. Free, no watermark, and nothing is uploaded.
What it doesThat's our app, so weigh the recommendation accordingly.
Because the tools stack, a common sequence takes one export rather than three: trim to the two seconds that matter, reverse, then slow it to 0.5x.
Route 3: a Mac
If the clip is already on a Mac, or is long enough that you'd rather not wait on the phone:
iMovie for Mac: select the clip in the timeline, open the speed controls above the viewer, and tick Reverse. Free, and it copes with long clips better than a phone does. (QuickTime Player, for all its other editing features, has no reverse.)
ffmpeg, for the terminal-inclined, reverses picture and sound together:
ffmpeg -i in.mp4 -vf reverse -af areverse out.mp4
It holds every frame in memory while it works, so trim a long clip first or it will exhaust your RAM.
The sound
Decide this before you export, because it changes how the result feels.
- Reversed audio is the faithful version: a splash un-splashes and the sound un-splashes with it. Speech becomes the familiar backwards gibberish, which is often the joke.
- Muted is right when the clip will sit under music, or when backwards speech would distract.
- Forward audio over reversed picture is almost never what you want. If an app does this silently, that's the tell that it only reversed the picture.
Length, and the thirty-second rule
Every reverse tool, on any device, does the same work: decode every frame, reorder, re-encode. A 10-second clip is quick. A five-minute 4K clip is a long wait and a lot of memory, and phone apps either refuse, cap the length, or quietly drop the resolution.
So trim first. Most reversed clips that get shared are under ten seconds, and reversing only the part you'll keep is faster than reversing everything and cutting afterwards.
Ideas that work well reversed
- Someone jumping out of a pool onto the edge.
- Pouring a drink, back into the bottle.
- Tearing up a page that reassembles itself.
- Walking backwards through a crowd that walks forwards.
- Anything thrown, which now flies into a waiting hand.
The trick in each is the same: film something with a clear direction and an irreversible-looking ending. The reverse does the rest.
