In the United States, Canada and the United Kingdom, grips are camera support equipment technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions: The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second function is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography.
Grips' responsibility is to build and maintain all the equipment that supports cameras. This equipment, which includes tripods, dollies, tracks, jibs, cranes, and static rigs, is constructed of delicate yet heavy duty parts requiring a high level of experience to operate and move. Every scene in a feature film is shot using one or more cameras, each mounted on highly complex, extremely expensive, heavy duty equipment. Grips assemble this equipment according to meticulous specifications and push, pull, mount or hang it from a variety of settings. The equipment can be as basic as a tripod standing on a studio floor, to hazardous operations such as mounting a camera on a 100 ft crane, or hanging it from a helicopter swooping above a mountain range.
Good Grips perform a crucial role in ensuring that the artifice of film is maintained, and that camera moves are as seamless as possible. Grips are usually requested by the DoP (Director of Photography) or the camera operator. Although the work is physically demanding and the hours are long, the work can be very rewarding. Many Grips work on both commercials and features.
In the UK, Australia and most parts of Europe, grips are not involved in lighting. In the "British System", adopted throughout Europe and the Commonwealth (excluding Canada), a grip is solely responsible for camera mounting and support.
The term "grip" is derived from an older term in U.S. theatre where it designated stagehands who moved scenery.U.S. grips typically belong to the International Alliance of Theatrical Stage Employees (IATSE). Canadian grips may also belong to IATSE or to Canada's other professional trade unions including Toronto's Nabet 700, or Vancouver's ACFC. British grips usually belong to BECTU (Broadcasting Entertainment Cinematograph & Theatre Union).
