May 2. 01. 6: Political broadcasting on the BBC is a national democratic tradition, covering a wide spectrum of momentous events.

Camera Supervisor and technocrane operator, Dave Box, has worked on the last three UK General Election BBC transmissions as well as the 2. European elections.

Box explains the intricate camera set- up that BBC Studioworks has implemented to capture every aspect of this immersive viewing experience.“The camera equipment used for the tracking system is assembled around 1.

BBC News broadcast style. He adds: “One of the biggest challenges when lighting Jeremy Vine’s green screen area of the studio is ensuring that the end effect looks realistic. Lighting is vital to the overall effect, as it adds another dimension to the CG graphics. It has to look real, and has to work technically too.

It’s our job to achieve the perfect balance and make these shots look as natural as possible.”As with the 2. General Elections, when Gibson also led the BBC Studioworks lighting team, he is making extensive use of automated lamps. For example, we could see a shot of Westminster, with Jeremy Vine walking past a window. We’d use the lamps to give the impression of where the light was coming from, and change its colour to make it appear like daylight.”The sound vote. Having completed a number of large- scale projects for the BBC over the past 3. BBC News, Sound Supervisor Gary Clarke has a wealth of experience in bringing one of the most crucial elements of any production to life – the audio.

A Studer Vista 8 mixing console is the backbone to the elections audio set- up. Contributions from presenter and guest microphones, outside sources, VT play- ins and grams are all added into the live mix. Elections involve complex communications and reverse feeds.

Close liaison between the various news technical departments and the audio broadcast operation is vital. An area at Elstree known as MCX handles the incoming and outgoing feeds. The broadcast audio is slightly delayed to match the vision delay introduced by computers providing the virtual reality graphics for Jeremy Vine.

It’s vital that the sound team ensure that all audio sources are synched with picture by the time they’re transmitted. Clarke explains: “As with all live broadcasts, much of the content will be unpredictable.

The key to ensuring that live broadcasts are a success is to have systems in place that are flexible and can deal with any eventuality.”A polished live production. Since the early days of elections broadcasting the off- screen challenge to provide a full- scale, live round- up of incoming news has always remained the same. But the talented professionals at the heart of the technical operation are what really brings the production to life. John O’Callaghan, Head of Studios and Post Production Services for BBC Studioworks, said: “We love orchestrating live events like this because we get to pull together what we’re great at – combining the most talented and dedicated people, with the right technology and facilities, to deliver our customers’ vision.

It’s the perfect showcase for BBC Studioworks’ capabilities.”.
