Anti-Gravity Rig

An Anti-Gravity Rig is a specialized, wearable camera support system. It is designed specifically to enhance the performance of a handheld gimbal. This device isolates the gimbal from the operator’s movements. This creates exceptionally smooth and fluid shots. Many professionals consider it a gold standard for dynamic gimbal operation. It allows the camera to glide through a scene.

How an Anti-Gravity Rig Works

The rig’s design is complex and effective. An operator first puts on a durable, nylon-based support vest. This vest distributes the system’s weight evenly across the operator’s torso. Attached to this vest is a system of support arms. These arms “fly” up and over the operator’s head. The gimbal is not held directly by the operator. Instead, it is suspended from these overhead arms. A complex series of pulleys often achieves this suspension. Some well-known systems, for example, use as many as 24 different pulleys to achieve perfect balance.

The Power of Isolation

This intricate pulley and arm system is the key to the rig’s performance. Its primary function is isolation. It almost completely separates the gimbal from the operator’s footsteps and body motion. When the operator walks or runs, the rig absorbs their natural up-and-down bounce. The pulley system constantly adjusts to neutralize this motion. This prevents the “step” bounce from transferring to the gimbal and the camera.

The “Gold Standard” for Gimbal Movement

The resulting footage is incredibly smooth. The camera appears to float or fly through the space. The rig’s stability is so effective that an operator can run in place, and the gimbal will remain perfectly level and stable. This level of isolation is impossible to achieve with a gimbal alone. It effectively “takes the steps out” of the shot.

This allows filmmakers to capture long, dynamic, and perfectly stable tracking shots. They can follow actors at a full run. They can also move over uneven terrain without the shot jarring or shaking. The Anti-Gravity Rig combines the flexibility of a gimbal with the smoothness of a much larger, more expensive dolly or Steadicam system.
