An interview has a subject and a host, not two equals. Giving the guest seventy percent keeps the visual hierarchy honest while the interviewer stays present enough to react.
An interview needs both faces. The conventional answer is two cameras and an edit that cuts between them, which is three problems: a second device, syncing, and the editing time.
One phone with both lenses running gets you both faces in one file, in sync, finished when you stop recording. What you give up is independent framing: you cannot push in on your guest without moving the whole rig.
For most interview content, that trade is worth making.
Why 70 / 30, landscape
An interview is not a conversation between equals, however friendly it is. Someone is the subject and someone is asking. 70 / 30 puts that hierarchy on screen: your guest gets the space, you stay visible enough that your reactions land.
Landscape, because interview footage is watched on YouTube and in players where horizontal is the native shape, and because two seated people simply fit a wide frame better.
Two variations worth knowing:
- Two hosts of equal standing: use 50/50. Equal billing is accurate there.
- Cutting vertical clips for social: switch to portrait and a stacked split. Frame far tighter than you would in landscape; at 9:16 each person only gets half the height.
Seating and the phone
Sit closer than feels natural. Both lenses have a fixed field of view. If your guest sits at conversational distance, they read as small and far away.
Get the phone at eye height. On a small tripod or propped on books, at roughly the seated eye line of whoever the rear camera is on. Low angles make people look imposing; high angles make them look diminished. Neither flatters an interview.
Check both previews before the guest sits down. The front camera is covering you, and it is easy to spend the whole take slightly out of frame because you only ever looked at their side.
Watch the backgrounds separately. The two views are different rooms as far as the viewer is concerned. A tidy shot of your guest against a cluttered shot of you undermines both.
The audio problem, stated plainly
This is the honest limitation and no layout fixes it: there is one microphone track. Whoever sits further from the phone will be quieter, and a phone mic in a room with hard surfaces picks up reverb from both directions.
If the interview matters:
- A lavalier mic on your guest is the single biggest improvement available, and costs less than an hour of editing.
- Failing that, record in a soft room: carpet, curtains, a sofa. Kitchens and empty offices are the worst rooms in most buildings.
- Keep the phone closer to the guest than to you. You can be quieter in the mix; they cannot.
Length and heat
Interviews run long, which is where simultaneous capture gets uncomfortable. Two pipelines plus live compositing generates heat, and iOS will eventually throttle or stop recording.
Practical approach: record at 1080p, take the case off, keep the phone off direct sun and away from a charger, and break a long interview into segments at natural pauses. Segments are also easier to edit and safer if something goes wrong.
