Electronic field production
Summary
Electronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location, special venue or fitting environment. Zettl defines EFP as using "both ENG (electronic news gathering) and studio techniques. From ENG it borrows its mobility and flexibility; from the studio it borrows its production care and quality control. EFP takes place on location (which may include shooting in someone's living room) and has to adapt to the location conditions... Good lighting and audio are always difficult to achieve in EFP, regardless of whether you are outdoors or indoors. Compared to ENG, in which you simply respond to a situation, EFP needs careful planning."
Typical applications of electronic field production include awards shows, concerts, major interviews for newsmagazine shows like Inside Edition, Extra and Dateline NBC, large conventions such as the Democratic National Convention, Republican National Convention or San Diego Comic-Con International, celebrity red-carpet events and sporting events.
EFP ranges from a camera operator or crew of two (camera operator with sound mixer) capturing high-quality imagery, to a multiple-camera setup utilizing videography, photography, advanced graphics and sound.
Sports television is one facet of EFP. Major television networks once owned their own production trucks for covering major events, but today, with the explosion in networks on cable and over-the-air, they rent television production trucks by the day or week from broadcast rental companies for more routine or remote broadcast productions.
A typical sports production truck includes:
A large video switcher with an external digital video effects (DVE) unit and several mix/effect busses, to allow the Television director flexibility in calling for certain visual effects in the broadcast.
Several tripod-mounted and handheld professional video cameras.
