Dual CameraHow to Record the Front and Back Camera at the Same Time on iPhone
Two ways to film the scene and your reaction in one take: Apple's Dual Capture on iPhone 17, and a dual camera app for every iPhone from the XR on.
Updated
If you have ever tried to film a view and your own reaction to it, you know the problem: by the time you flip the camera around, the moment is gone. Recording both lenses at once solves it, and every iPhone released since 2018 has the hardware to do it.
What has changed recently is how you get at it. Apple finally built the feature into the Camera app, but only on the iPhone 17. On everything older, you need an app. This guide covers both routes.
The short answer
On an iPhone 17, iPhone Air, 17 Pro or 17 Pro Max: open the Camera app, switch to Video, tap the six-dot control and choose Dual Capture. You get one fixed picture-in-picture layout.
On an iPhone XR through iPhone 16, or if you want a layout Apple does not offer: install a dual camera app. Dual Camera gives you split screen, picture-in-picture, side by side and single lens, at up to 4K.
Both routes produce a single video file. Neither requires editing afterwards.
Route 1: the app (iPhone XR and later)
This is the route that works on the widest range of hardware, and the only one available if your iPhone predates the 17.
- Install the app. Download Dual Camera from the App Store. It needs iOS 18.6 or later.
- Allow camera and microphone access. Multi-camera capture will not start without both.
- Pick your layout before you frame the shot. Switching mid-take is not the point, and it changes how you compose.
- Choose your resolution. 4K if the footage is going to be edited or published somewhere large. 1080p if you are recording something long, because it generates less heat and takes less space.
- Check both previews. You see the rear feed and the front feed live, so there are no surprises.
- Hit record. The composite is rendered as you film. Stop recording and the finished clip is already in your library.
Which layout to use
| Layout | Best for | Why |
|---|---|---|
| Picture-in-picture | Reactions, commentary | Keeps the scene dominant, your face small but present |
| Split screen | Two-person conversation, before/after | Gives both views equal weight, stacked vertically |
| Side by side | Landscape framing, interviews | Vertical split reads well on a wide screen |
| Single lens | Mid-shoot switch | Drop to one camera without leaving the app |
Picture-in-picture is the safe default for vertical social video. Split screen is the one people underuse. It works far better than PiP when both sides of the frame actually matter, like an interview or a reaction where the reaction is the content.
Route 2: Apple’s built-in Dual Capture (iPhone 17 only)
If you have an iPhone from the 17 lineup, the Camera app can do a version of this natively:
- Open Camera and swipe to Video.
- Tap the six-dot icon in the top-right corner.
- Choose Dual Capture.
- A small front-camera window appears over the rear-camera view. Drag it wherever you want it.
- Tap the shutter to record.
It records at 1080p or 4K, at 24 or 30fps, and saves one file.
The catch is that the layout is fixed. The rear camera always fills the frame and the front camera is always the small window. You cannot swap them, and there is no split-screen option. If you drag the small window mid-recording, that movement is baked into the final video. For a fuller breakdown, see iPhone 17 Dual Capture explained.
What you need for either route
There are exactly two requirements, and they are easy to check:
- An iPhone XR or later. Simultaneous capture needs an A12 Bionic chip or newer. This is a hardware limit, not something a software update can fix.
- iOS 18.6 or later for the app route.
If you are not sure where your model sits, the iPhone dual camera compatibility table lists every model.
Five things worth knowing before you film
It gets warm. Two camera pipelines plus live compositing is genuinely demanding. On a long take the phone heats up, and iOS will eventually throttle or stop recording to protect itself. If you need a twenty-minute continuous take, drop to 1080p and take the case off.
Battery drains fast. Budget roughly double what a normal video would cost you. For a shoot day, bring a battery pack.
Files are large. A 4K dual-camera minute is a big file. Check your free storage before a shoot, not during.
Audio is one track. You get a single microphone recording, not separate audio per lens. If you are filming an interview where both people need clean sound, an external mic is still the answer.
Frame for the layout, not the shot. With picture-in-picture, whatever sits in the corner where the small window lands is hidden. With split screen you have half the vertical space per view, so subjects need to be closer than instinct suggests.
When a second camera is still better
Dual camera recording is not a replacement for a two-camera setup. You are locked to one position, one exposure decision that has to work for both feeds, and one audio source. For anything where the two angles need independent framing or you want to cut between them in post, film separately.
Where it wins is everything else: the reaction you cannot stage twice, the vlog where flipping the camera costs you the moment, the tutorial where the viewer needs to see your hands and your face. One phone, one take, done when you stop recording.
Get started
Dual Camera is free to download and works on iPhone XR and later. Pick a layout, hit record, and both sides of the moment end up in the same file.
