Children In Need will be broadcast in HD for the first time this weekend.

The seven-hour TV marathon, which airs today (Friday 20 November), will transmit on BBC1 and BBC HD from TV Centre’s Studio One using 13 Sony 1500 HD cameras.

BBC Studios and Post Production is providing cameras, sound and lighting craft teams, including camera supervisor Nigel Saunders, sound supervisor Tony Revell and Dave Gibson, lighting director.

Teams at both facilities have spent six weeks producing HD insert and appeal films, including The One Show cast recreating Fame and a musical extravaganza from EastEnders’ Albert Square.

A series of HD upgrades have been made to the facility’s replay and VT Multiplexer areas to support this and future live HD projects.

On the night, they will be using EVS servers and a HD fast-turnaround edit facility to service the close-to-air editing requirements for concert and studio footage, insert play-in operation, and highlight package elements of the show.

Nine OBs will deliver a mix of HD and SD feeds into TV Centre.
