The number that travelled was 300 cameras. The one worth your attention is smaller and lives in a rack: 46. That is how many Atomos Shogun Studio 2 recorders sat behind the set of the MrBeast video that puts one person of every age, from one to a hundred, in individual cubes — and they are why a large part of that set recorded with no card in the camera at all.
That is a production decision, not a gadget. But it has a one-camera version, and it solves the same problem.
What 46 rack recorders were doing back there
Atomos published its own account of the shoot — worth reading as what it is, a recorder maker writing up a production that used its recorders — and the crew's reasoning is in it: they ran cameras on mains power and recorded remotely, because swapping batteries and memory cards over and over was not workable given how much it would have disturbed the contestants. Jason Elliott, MrBeast's director of photography, framed the same constraint differently when VP Land wrote up the production: the camera team has a policy of not interfering with or influencing contestants.
The hardware follows from that. A Shogun Studio 2 is a 3RU rack unit that records several camera feeds at once onto media that lives in the rack, on redundant dual power supplies. Nothing about it is exotic. It is a place to put the recording that is not the camera.
Forty-six racks are not 300 cameras, and were never meant to be. By the published account the cubes were covered by GoPro Hero 12s with media mods and Marshall POV cameras — bodies that keep their own media. What the racks took was the part of the set that could be cabled. VP Land's write-up carries the rest of the scale: 100 tablets, close to 56 miles of cable, petabytes of footage, and a post team that spent hundreds of hours on it because nothing was scripted.
The problem was never storage. It was having to walk over there.
A memory card is a clock. So is a battery. Both of them set a time at which a person has to stand next to the camera, and on a set built around contestants who must not be influenced, that walk is the expensive part. Not the card.
Your version of that is smaller and the same shape. An interview that runs past the card. A locked-off second angle at a wedding. A long timelapse on a balcony. A camera pointed at a workbench while both your hands are busy. In none of those is the limit how much footage you can store — it is that the storage lives inside a thing you would rather not touch.
What it costs: cable, and a wall socket
Moving the recording out of the camera does not remove the constraint. It moves it into two other places, and both are physical.
The first is cable. Every camera recording to a rack is a physical run that has to survive people walking past it for as long as the shoot lasts. Close to 56 miles is what that looks like at this scale.
The second is power. Running the cameras off the mains removes the battery clock, but it trades a battery for a socket, and a camera tied to a socket has stopped being portable. The redundant supplies on the Shogun Studio 2 are the tell: once several cameras' footage depends on one box, that box failing is a different category of problem from a card filling up. Rigs fail on set for unglamorous reasons, and centralising the recording changes which reasons matter.
The one-camera version of the same idea
Three routes exist, and which of them are open to you depends entirely on the body you already own.
An external recorder over HDMI or SDI. The rack idea in a monitor-sized box. It works with most cameras that put out a clean signal, and hands you a screen you can actually see.
The camera writing straight to a USB SSD. Panasonic documents this on several recent Lumix bodies. Most Nikon Z bodies cannot, because they do not act as a USB host. It is a per-model capability, not a category, so your body's manual is the only answer worth trusting.
Your phone. On iPhone 15 Pro and later, Apple supports recording ProRes straight to an external drive over USB-C, and its support documentation is specific about the conditions: the drive has to be formatted exFAT, the cable has to be USB 3 at 10Gb/s, and 4K60 ProRes needs a drive that sustains at least 220MB per second. Password-protected drives are not supported.
For the battery half of the problem, a dummy battery with a mains adapter does for one camera what mains power did for a set full of them.
What it buys you, and what it does not
It improves nothing you shoot. Same sensor, same lens, same light. What it buys is unattended runtime, and a file already sitting on the drive you will edit from — offloading is the part of the day people forget to count. At production scale that arithmetic turns absurd; at yours it is an hour you get back.
What it costs is a rig that is no longer grab-and-go: one more cable, one more thing to power, one more thing that can fail. If you shoot handheld and you move, cards win, and it is not close. And if somebody is standing beside the camera anyway, the card was never the thing slowing you down.
The camera count is the figure these productions get remembered for, and it is the least interesting number in them. The record count on another shoot bought coverage, not quality, and the two get confused constantly. If you are building a multi-angle rig of your own, the GoPro side of this kind of set is the closer parallel: small bodies, their own cards, and the sync problem that arrives with them.
