How to film a get ready with me (GRWM) video with both iPhone cameras
A GRWM is really two things filmed at once: you talking through what you are doing, and the doing itself — the products, the mirror, the outfit. Filming it with a single dual-camera app instead of propping up the front camera and recording a separate voiceover afterwards means both halves land in the same file from the first second, with nothing to line up later.
Setting up simultaneous recording in general is covered elsewhere. What is specific to a GRWM is smaller and more practical: which camera should carry your face, how to fit a bathroom counter into a canvas that is taller than it is wide, what happens to the light when the routine moves from the bathroom to the closet, and why you should plan the shoot as a handful of takes rather than one unbroken recording.
Which camera carries your face
Picture-in-picture is the natural default here, for the same reason it works for a tutorial: the routine is what someone came to watch, and your voice explains it rather than competing with it for space. Let the back camera fill the frame with the counter, the mirror and your hands, and keep your face as the inset. Which camera fills the frame and which one is the small window can be swapped, so if you would rather lead with a close talking shot and only cut to the counter for product reveals, that works too — decide the emphasis before you start, because it is easier to plan than to fix afterwards.
A split layout is worth considering only when the two halves genuinely deserve equal weight — an outfit reveal at the very end, say, where you want the finished look and your reaction side by side. For the bulk of a routine, a straight split gives the counter half less room than picture-in-picture does, which works against you rather than for you.
The counter is smaller than the shot you want
A phone camera image is a wide 16:9 frame; the canvas you are recording into is a tall 1080×1920 or 1080×2340. Fitting a vanity counter, a mirror and you into that shape, at the distance a bathroom actually allows, is the hardest part of a GRWM — most bathrooms do not give you room to step back. If your back camera has an ultra wide option, this is the moment to use it: a wider field of view buys back some of the distance the room will not give you.
Lens choice on the back camera is one of the settings that locks in once you press record, the same as resolution, so decide it during a quick preview check before you start, not partway through when you realise the frame is too tight.
Your hands are full — plan where the phone actually sits
A tutorial can often be held; a GRWM mostly cannot, because both hands are usually occupied with a brush, a curling iron or a zipper. Prop the phone against something solid at roughly chest height rather than laying it flat on the counter looking up — it is the difference between a shot that reads as intentional and one that reads as an accident. A few seconds of countdown before you start is useful here specifically, because those are the seconds you need to get back into position with your hands already full; DualCam’s countdown can be set to 3, 5 or 10 seconds, and like resolution, it has to be set before you press record.
The light changes when the room does
The front and back cameras each expose for whatever they are pointed at, independently of one another — a fact that shows up in almost every dual recording, but a GRWM runs into it more than most, because the routine genuinely moves through different light. Vanity lighting around a bathroom mirror is usually warm and close; a bedroom or closet a few steps away is lit completely differently. Moving between them mid-routine means the back camera and the front camera are each renegotiating exposure against a different scene every time you change rooms.
There is no setting that reconciles this after the fact, since the frame is composited and written as you shoot. The practical fix is to do as much of the routine as reasonably fits in one consistently lit spot, and treat a genuine room change — say, moving to a full-length mirror for the outfit — as its own take rather than a continuation of the same one.
Shoot it as steps, not one unbroken take
A dual-camera recording runs straight through from record to stop, with no pause button in the middle, so a twenty-minute routine cannot be one recording with a break for a phone call or a wardrobe change built into it. That is less of a limitation than it sounds, because a GRWM already has natural seams — skincare, then makeup, then hair, then the outfit — and each of those is a clean place to stop and start a fresh take, not a place you would want a pause anyway.
Stopping finalizes and saves the take immediately, so a shoot in five or six short takes is not a riskier plan than one long recording — if anything it is the safer one, since a mistake in one step only costs that step. Stitching the steps into a single video afterwards is an editing decision, not a recording-time one.
Common follow-up questions
Do I need an actual mirror for this to work?
No. Propping the phone on the counter facing you does the job — the back camera sees the room and your hands, the front camera sees your face, and nothing needs to bounce off a reflection to get both into the frame.
Can I switch from a close talking shot to the wide counter shot partway through?
Swapping which camera fills the frame and which one is the inset works mid-recording, along with the inset’s corner, size and shape. Which back lens you are using does not — that one is set before you press record, the same as resolution.
What if the routine runs long — will I lose the file if something interrupts it?
No. Whatever ends a recording — you pressing stop, a call coming in, the phone overheating — finalizes the file rather than corrupting it. Shooting in the short takes described above just means an interruption costs you one step, not the whole routine.
Want to just do this?
DualCam records the iPhone front and back cameras at the same time and writes one finished MP4 while you shoot. Free, no account, no ads, nothing leaves the phone.
