Multi-location broadcast production and mastered program delivery.

Overview

Expertise France produces “Rendez-Vous de l’Expertise”, a series built around conversations with specialists. For an episode on decent work, the production moved across five Mexico City locations in three days: the French Ambassador’s residence, a studio session, a muralist’s work in La Magdalena Contreras, an outdoor interview in Coyoacán’s Jardín Hidalgo and a round table with international experts joining by Zoom.

The challenge

Each location had its own light, acoustics and constraints, and none could be reshot. The final program had to read as one broadcast, with remote guests treated as full participants and institutional graphics matching Expertise France’s standards.

Agreed scope

  • Six segments across five locations in three days
  • Matched camera and colour treatment across very different spaces
  • Remote guests by Zoom integrated into the live production
  • Clear audio in open-air segments
  • Institutional branding, lower thirds and identifiers applied live
  • A finished, mastered program file on handover

Technical workflow

Multicamera package

A full-frame Sony FX6 led coverage, with a Sony FR7 PTZ and two secondary cameras.

Zoom in the signal chain

Remote participants joined through Zoom Webinar routed directly into the live switcher.

Live graphics

Branding and lower thirds ran on a Barco S3 and Resolume Arena, separate from camera feeds.

Audio at every location

An Allen & Heath SQ5 mix with multitrack capture in Reaper at each location.

Preparation and testing

With no option to return to a location, recording protection was designed into the chain.

  • ISO and program recordings at three points in the signal chain
  • Multitrack audio capture at every location
  • Portable lighting controlled from one console across all locations

Operational challenges and response

Open-air segments with wind and street noise.

Wireless and lavalier microphones with multitrack capture kept dialogue usable.

Five different lighting environments.

Portable LED panels gave consistent, controllable light from the residence to the garden.

Confirmed outcomes

  • A complete multi-location program was delivered from five Mexico City locations over three days.
  • International specialists joining by Zoom were integrated into the round table.
  • No reshoot was required at any location.
  • A mastered program file was handed over on schedule.

Outcomes as documented in the published case. We do not add figures the project did not record.

The lesson

When a shoot cannot be repeated, protection has to be designed into the signal chain.

Questions this project answers

General answers, with this case as a real example.

Can an event be recorded without being livestreamed?

Yes. Recording is its own deliverable and does not require a stream. We can record the switched program, each camera separately, the presentations, or a combination.

Agree the file formats, audio channels, storage and delivery date in the proposal, and say whether the material will be edited later. For Expertise France, ISO and program recordings at three points in the chain produced a mastered program with no reshoots.

Can remote speakers participate?

Yes. We bring remote speakers into the room and the program through Zoom, Teams or a similar platform, with return audio so they can hear the room and follow cues.

Results depend on the speaker’s connection, camera, microphone and lighting, so we recommend a technical check with each remote speaker before the event and keep a fallback for their content, such as a pre-recorded version, when the moment is critical.

Do you work with Zoom and Microsoft Teams?

Yes. Zoom and Teams can bring remote speakers into the room, carry the program to remote employees, or both. We connect them as production sources rather than leaving a laptop pointed at the stage.

Meeting settings, host rights and audio routing need testing with the account owner, because two meetings on the same platform can behave differently. ITP Aero’s All Hands ran on Teams; ICON’s Mexico hub connected into DV4’s Zoom studio.

Can you connect multiple locations?

Yes. We connect rooms, floors, offices or cities into one program, either by producing each location or by building the local hub inside a wider workflow.

Multi-site work depends on clear rules: which location sends what, who directs, how timing is handled and how teams talk to each other during the show.
