DualCapture

Picture-in-picture camera for iPhone

A PiP camera records the back camera full frame and floats the selfie camera in a corner on top. DualCapture does that live on iPhone and writes the result as one video.

The three DualCapture layout families: vertical split screen, horizontal split screen and picture-in-picture

What a picture-in-picture camera actually does

Picture-in-picture is the layout you have seen on every gaming stream and half the tutorials on YouTube: the main footage fills the frame, and a small window in one corner shows the person talking.

Doing it in an editor means two clips, two timelines and a mask. Doing it in a PiP camera app means neither. Both iPhone lenses record at the same time, the overlay is composited while you shoot, and what lands in Photos is already the finished shape.

The overlay is not a filter drawn on afterwards. It is a second live camera, so your expression is genuinely simultaneous with what the back camera saw.

Four corners, and a full-screen alternative

DualCapture puts the selfie window in the top left, top right, bottom left or bottom right. Pick the corner that keeps your face off whatever matters in the main shot. The window is a fixed size, big enough to read an expression and small enough to stay out of the way.

If the corner window is too small for what you are filming, the same app has split screen. The cameras go side by side or stacked, and the divider between them is draggable, so a subject that needs more room can have it. Pick between the two before you start, because the layout is locked once the recording is running.

What you can change mid-take is which camera is which. Tap the swap control and the feeds trade places, so the selfie takes the full frame and the scene drops into the inset. The merged file follows along.

Photos too, not only video

The mode switch under the preview flips between video and photo. In photo mode a single tap captures both cameras, and you get the selfie and the view as separate images.

It is the easiest way to prove you were somewhere. One press, two photos, no handing your phone to a stranger.

What you get back from one take

Tapping stop writes five files to your Photos library: a vertical merge, a horizontal merge, the front camera alone, the back camera alone. Nothing to export, nothing to wait on.

Keeping the individual clips matters more than it sounds. The merged PiP video is a rendered composite, so you cannot move the overlay later. The raw clips let you redo the layout in an editor whenever the corner you picked turns out to be the wrong one. Exports carry no watermark and recordings have no time limit.

Recording quality goes to 4K at 60 fps, with 24 and 30 fps if you want smaller files. Stabilization is a toggle in Settings and applies to the back lens.

Requirements, and what iOS already gives you

DualCapture needs iOS 18 or later and an iPhone with multi-camera support, which means iPhone 15 or newer. Free to download. Premium adds 4K, every layout and unlimited exports, as a subscription or a one-time lifetime purchase.

iOS 26 brought a Dual Capture mode to Apple's Camera app, and it is picture-in-picture by design: big rear frame, small front overlay you drag around the screen while recording. On the Pro models you can change rear lenses mid-take. If you have an iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max or an iPhone Air, try that first, because it costs nothing. It gives you one layout and one output file, and it does not exist on any older phone.

{t.faq}

What is a PiP camera app?

One that records the front and back cameras at the same time and puts the front camera in a small window over the back camera's full-frame footage, live, while you shoot.

Can I move the picture-in-picture window?

You choose one of four corners before recording. The window size is fixed. If you need the front camera larger, split screen with a draggable divider is the better layout.

Does the overlay show up in the saved video?

Yes. The merged files are composited with the overlay in place. The separate front and back clips are also saved, so you can rebuild the layout differently later.

Can I take picture-in-picture photos?

Photo mode captures both cameras with one tap and saves them as separate images.

Is picture-in-picture available for free?

The app is free to download and record with. Premium covers 4K, every layout and unlimited exports.

Which iPhones can do this?

Any iPhone with multi-camera capture support, running iOS 18 or later. DualCapture lists iPhone 15 and newer.
