Yes, an iPhone can record from the front and back cameras at the same time. Apple added multi-camera capture in iOS 13, and iPhone 11 and newer models support it. The catch: the built-in Camera app does not offer it, so you need a third-party app. In Video Buffer Action Camera, pick Dual Camera in the camera picker and both feeds record together as one picture-in-picture video.
Why the built-in Camera app cannot do it
The hardware and the system support it, but Apple never surfaced it in the Camera app. If you have tried to film your kid's goal and your own reaction, you know the workaround: two phones, or one phone spun around a half-second too late, or a reaction that exists only in memory. Since iOS 13, apps can open two cameras through the same capture session and record both streams at once. All that is missing is an app that does it.
How Dual Camera mode works
In Video Buffer Action Camera, open the camera picker and choose Dual Camera. The back camera fills the frame and the front camera appears as a picture-in-picture inset, both recording simultaneously into a single video file. There is no syncing two clips in an editor afterward, because there is only one clip. What you see on screen is what gets saved.
One honest limitation: in dual-camera mode the resolution and frame rate are fixed, and the app tells you so when you switch. Running two cameras at once is heavy work for the phone, so the system locks the format to keep both streams smooth. For single-camera recording you get the full menu of formats, up to 4K and 240 fps.
The twist: dual camera plus a rolling buffer
Plenty of apps can show two cameras. What makes this combination different is that Dual Camera works with the app's rolling buffer. The app continuously holds the last stretch of both feeds in memory, and when you tap record, the saved clip starts seconds before your tap, on both cameras.
That matters because the best dual-camera moments are exactly the ones you cannot predict. The goal and the gasp happen together, once, and then they are gone. With the buffer, you tap after the moment and get both halves of it:
- Kid's goal + parent's face. The phone watches the field, the front camera watches you. One tap after the goal saves the play and the celebration.
- Road + learner driver. This one comes straight from driving instructors, who specifically asked for the picture-in-picture dual camera: not two separate clips, but the road and the student in one frame. The back camera watches the road, the front camera watches the learner, and when a situation is worth discussing, the instructor taps once and the last seconds of both are saved together: the roundabout and the mirror checks, the sudden brake and the reaction. The debrief happens with evidence instead of memory, and there is nothing to sync afterward because it was never two videos.
- Road + cabin. A dash cam view of the traffic and a view of the driver, in one file, with the seconds before the incident included.
- Performer + audience. The stage in the main frame, the crowd's reaction in the inset.
- Athlete + coach's view. The back camera on the drill, the front camera on the coach narrating what to watch for.
Classic dual-camera uses still work
You do not need the buffer angle to get value out of two cameras. Reaction videos, where your face responds to something you are filming, are the obvious one. Unboxings and vlogs get the product and the presenter in a single take. And commuters get a two-view dash cam out of the phone already mounted on the windshield.
Which iPhones support it
Multi-camera capture needs an iPhone 11 or newer. The app checks your device, and the camera picker only shows Dual Camera when your iPhone actually supports it, so there is no way to select a mode that would fail. On older devices you simply see the regular front and back camera options.
Do this in Video Buffer Action Camera
Pick Dual Camera in the camera picker and both cameras record into one picture-in-picture video, backed by the same rolling buffer as every other mode. Set the Buffer duration, tap after the moment, and the clip includes the seconds before your tap on both feeds. Trigger it from the screen, a volume button, or your Apple Watch, and save to Photos, Files, or iCloud Drive.
