Teach you how to play the role of the camera crane in the film

The camera crane is more and more widely used by TV stations and advertising companies as a special video camera auxiliary equipment. Especially in some enterprises and institutions, such as image feature, advertising shooting, square performance and some other MTV programs, the use of camera crane can really add power to the picture. And how to correctly use the camera crane and the use of the camera crane is a problem that the cameraman needs to discuss. Here we share the work experience of the author in recent years.

In program production, the most widely used rocker is to use its motion lens to enhance the motion of the screen, and sometimes use it as a high fixed point. But that's not the advantage of the rocker. The most basic requirements for using the camera crane are three words: steady, uniform and accurate. The picture is steady, and falls when the force should be stable, can make the camera crane shaking; uniform, speed is in the process of movement should be uniform, objective movement is clear, not unsteadiness; quasi, is the subject, exercise process should be taken on purpose, especially the single subject, relative the main position in the screen to be fixed, must not be lost in the process in motion subject.

If you want to be stable, uniform and accurate, we need a solid basic skill. The basic operation of rocker camera includes several aspects: arm movement, camera pointing control, zoom control, focal length adjustment and so on (if Z axis components are installed, there is Z axis manipulation). The coordination between arm motion and camera lens pointing is the premise of using camera crane well, especially when moving around the target body. Moreover, as the camera zoom lens is gradually pushed closer to the main body, the difficulty of operation will be increased. Master the basic skills to rely on the usual practice, in a day. A beginner must have at least a few hours of basic training to master it. Each rocker user must practice solid basic skills, to ease up control.

With a solid basic skill, we are going to study the placement of the camera crane in the program, that is, the location of the camera crane. In my opinion, the advantage of large camera crane (above 7m) is in mobile shooting, which is not realized by the general machine. The effect of moving shooting is very related to the pre design of the motion trajectory. The range of the motion of the camera crane is a circle on the horizontal plane. Generally, we only use a section of the circular arc MN. On the vertical plane, it is a fan type and usually uses a section of the arc. The motion of the camera is the synthesis of the arc motion on the horizontal and vertical surfaces. In general, the camera crane shift is not very convenient, the scene in the program is basically fixed, especially in one broadcast occasion. So, before rehearsing, we should study the program seriously, such as how people appear, stand, position on the stage, and the number of dances. Based on "understanding" program, design camera motion, the maximum to meet the needs of the program, give full play to the advantages of the program produce rocker, the biggest artistic appeal. Once the track is determined, the position of the camera crane is determined. If it's a segmented recording program, it is necessary to move the camera crane position to adapt to different trajectories according to the need, so there are more than one location. It is necessary to mark the ground in advance, and it is best to hang an object under the O point of the tripod to locate it accurately.
