Motor-driven head with worm gear — remote-controlled pan and tilt with millimeter precision. Essential for timelapse, loops, and mechanical perfection.
The geared head — known in English as a Geared Head or Pan-Tilt Head — is a motorized camera head with a worm gear mechanism that executes pan and tilt movements with precision. Unlike a fluid head, which relies on friction, the geared head operates with mechanical gears. This enables repeatable, precisely controllable movements — a requirement that is impossible with conventional manual pans.
On set, the geared head is used where the camera needs to perform movements in loops or cycles: timelapse sequences over hours, where the sky slowly moves over a building; product shots requiring a 360-degree rotation; or VFX shots where multiple takes with identical camera movements are necessary. The big advantage: the movement is mechanically stored — each subsequent take reproduces the exact path without manual adjustment. This saves time and makes compositing significantly easier.
Practically, it works like this: the head is programmed via a remote control or directly via controllers. The movement is input once — a pan from left to right, plus a subtle tilt upwards — and the motor stores the control impulses. The mechanism then plays back this sequence any number of times, always identically. The speed can be adjusted continuously, from imperceptibly slow (ideal for timelapses with 10-second cycles) to normal playback speed. For long, uncut shots, this is invaluable because the movement is guaranteed to be smooth and free of jerks.
However, the geared head requires more stable tripods than a standard fluid head — the motor load and the continuous load during looping demand robust supports. The setup is also more time-consuming, and the technology is more susceptible to wear and tear with intensive use. This should be considered in the budget. However, for those shooting digital or analog endless loops, planning a hyperlapse, or needing to duplicate VFX moves precisely, a good geared head is indispensable. The precision pays off.
