iPhones ringing the band, synced over a wired network from one iPad

Taichi Kimura's video for Kroi's "Method" used around forty-seven iPhones, forty-plus in use with the rest as backups, arranged 360 degrees around the band.

System designer Seiji Uchida: "We installed the Blackmagic Camera app on every iPhone, synced them using the Tentacle Sync app, and set up a wired network so all devices could be controlled from a single iPad… I tested it, and it worked flawlessly with 40 cameras." Each phone recorded to its own internal storage.

Kimura on why not cinema cameras: "At first, I actually wanted to shoot it with 40 VHS cameras. But that was technically difficult, and renting 40 cinema cameras wasn't realistic from a budget standpoint. So we decided on iPhones, since they look cool even when they appear in the shot."
