Conducting in-person interviews — whether for journalism, corporate testimonials, recruiting, or documentary storytelling — traditionally required two separate cameras on tripods, two camera operators, and time-consuming manual audio syncing in post-production. With modern iPhone hardware and DualCam, you can capture both the interviewer and the subject simultaneously using a single iPhone.
Two Dual-Camera Interview Configurations
| Setup Type | Lens Pairing | Seating Position | Best For |
|---|---|---|---|
| Face-to-Face | Front Selfie + Rear Wide (1x) | Interviewer and subject seated opposite each other | Intimate Q&A, investigative interviews, podcast chats |
| Adjacent (Same Side) | Rear Ultra-Wide (0.5x) + Rear Telephoto (3x/5x) | Both seated next to each other facing the phone | Panel chats, dual testimonials, press conferences |
Audio Capture for Two Speakers
Clean dialogue is the backbone of any professional interview. To record pristine sound from two speakers:
- Dual Wireless Lavalier Microphones: Connect a dual-transmitter system (such as Røde Wireless PRO or DJI Mic 2) directly into your iPhone's Lightning or USB-C port.
- Directional Separation: If recording in stereo mode, map the interviewer to the Left channel and the subject to the Right channel for independent gain control in editing.
- Wind & Noise Protection: Use foam windshields indoors and furry deadcats outdoors to eliminate ambient air turbulence.
Tripod Placement & Eyeline Rules
- Set Eye Level: Position your tripod so the iPhone camera is level with the subject's eyes. Filming from below looks unflattering; filming from above feels disconnected.
- The 180-Degree Rule: When seating interviewer and subject opposite each other, place the iPhone along the conversational axis so their gaze directions remain consistent in split-screen playback.
- Frame Stability: Use a weighted tripod or desk clamp to prevent accidental shakes when gestures occur.

Step-by-Step Recording Flow in DualCam
- Set up your seating and position the iPhone between interviewer and subject.
- Open DualCam and connect your dual-channel microphone receiver.
- Select your camera pairing (Front + Rear for face-to-face, Dual Rear for adjacent seating).
- Configure resolution in Pro Settings: 4K @ 30fps in HEVC provides optimal clarity and manageable file sizes.
- Hit record. Both perspectives capture into synchronized high-resolution video files in Apple Photos.
