Each production varies, some require a crew of about 12-16 to make sure the production goes smoothly. There are usually one or two other trucks following the main production truck with some of the equipment not able to fit in the main truck, as well as an ''uplink truck'' required to transmit the video back to the studio via a communications satellite. There are companies that contain both the functions of a satellite truck and production truck in a single truck body to save space, time and are considerably low cost. Other television production trucks are smaller in size and generally require two or three people in the field to manage. For instance broadcast journalism news reporters providing live television, local news in the field electronic news gathering (ENG) outside a formal television studio.
