On some Saturday mornings, a café terrace in the south of France becomes a live TV studio. Cameras go up, guests clip on wireless mics, and a local talk show streams to YouTube. There is no truck, no power cable, and no rack of gear. The whole control room sits on one device: YoloBox Extreme.
The man behind it is Gilbert Wayenborgh, a veteran broadcast consultant and co-founder of TV Lunel. This is how he built a TV studio that packs into a backpack.
Meet Gilbert: 30 years of broadcast, now on the road
Gilbert has spent three decades connecting cameras, networks and people. He designs TV studios and WebTV channels for companies and local governments. He specializes in IP video, trains professionals, writes for French trade press, and moderates panels at industry events.
In Lunel, a town between Montpellier and Nîmes, he co-founded TV Lunel. It is an independent local channel covering the town’s news, economy and community life. One of its flagship shows is Lunel-Asso, where host Gilles Bonnière-Soto interviews local nonprofits.
The challenge: a TV studio where there is no studio
Lunel-Asso is filmed on the terrace of O Vin Cochon, a café on the town’s main boulevard. Gilbert calls it a pop-up TV studio. The idea is to bring a real studio to where the stories are, instead of bringing guests to a studio.
That comes with tough constraints:
- No power. Cables across a busy public terrace are a safety and logistics problem.
- Limited space and crew. Every extra camera means another tripod, operator and setup step.
- Real broadcast standards. Multiple angles, clean audio, and a show that stays live.
“It’s not about filming someone with a camera. It’s about producing a real show, with a host, guests, multiple angles and live direction.” — Gilbert Wayenborgh
The setup
On Saturday, October 10, 2026, three nonprofits came on air. Gilbert’s kit for the day:
- Canon XA60 and Canon LEGRIA HF G50 camcorders
- A JVC camera for an extra angle
- A webcam pointed down the boulevard for an ambient shot
- Two wireless microphones, one for the host and one for the guest
- A mobile router for the live connection
- YoloBox Extreme at the center, switching, recording and streaming
Everything ran on batteries. Nothing was plugged into the café’s sockets.
Five angles from two cameras
Gilbert used YoloBox Extreme’s Replicate and Crop functions to turn two Canon camcorders into five shots. He set up two framings of the host, two of the guest, and one two-shot of both.
That gave the live edit the rhythm of a much bigger production. He did it without extra cameras, tripods or operators.
“Two cameras no longer means only two shots.” — Gilbert Wayenborgh
His tip for anyone trying this: frame your source shots a little wider. If you can, shoot 4K for a 1080p program, so the crops keep their sharpness.
Five hours on set, half the battery left
In a separate session, Gilbert ran YoloBox Extreme from 2 p.m. to 7 p.m. with no external power. He recorded six segments, each capturing the program feed plus four HDMI sources. At the end, the battery still showed about 50%.
“Five hours of production and half the battery still available. That seriously changes how you think about a mobile control room.” — Gilbert Wayenborgh
He ran everything in 1080p on purpose. His method is to validate a stable workflow first, then add more demanding settings step by step.
Record everything, fix it in post
YoloBox Extreme records the live program and each camera feed separately (ISO recording). For a weekly interview show, that is a safety net. The live cut is ready to publish right away, and the isolated feeds are there if a shot needs fixing in editing.
The live stream to YouTube held steady across his productions.
A control room that fits in a backpack
For Gilbert, the biggest change is mobility. Multicam used to mean switchers, monitors, recorders, an audio desk and a power supply. Now the heart of his control room fits in a backpack.
“I can set up a control room on a terrace, record multiple sources, direct a show, stream it to YouTube, and leave with the essentials of my kit in a backpack.” — Gilbert Wayenborgh
That matters for local TV. A crew this light can go to nonprofits, local businesses and residents, instead of waiting for them to come to a studio.
