Interrotron
Three cameras. Every voice. All at once.
Interrotron turns an iPhone into a three-camera interview rig. It records the telephoto, the wide and the front camera at the same time, together with the iPhone's stereo microphone and an AirPods microphone. Every camera and every microphone lands in its own file. Nothing is mixed down, so you get every angle and every voice to cut together later.
Interview someone across the room
Set your AirPods' microphone to one side, give the subject that AirPod and keep the other. The subject's AirPod records their voice up close, across the room. Interrotron can play it into the videographer's ear, and play the iPhone's microphone (the videographer's questions) into the subject's ear. Nobody has to shout across the room.
Every routing tap is spoken into both AirPods ("Left AirPod receiving iPhone microphone audio"), so both of you know what you're hearing. How to set up an interview.
Three cameras
The telephoto switches between 4× and 8×, the wide between 1× and 2×, and the front camera faces you. The iPhone has a budget for running cameras together, and Interrotron starts at 4K and steps down until all three fit. On iPhone 17 Pro that is 4K on the wide camera and 1080p on the telephoto and front. Three cameras at 4K is beyond what the phone allows. On iPhone 17 Pro it can also record ProRes. All the features.
Interrotron is in development for iPhone. Coming to the App Store.
