Vibration isolation

Definition

Vibration isolation is a technique used to reduce the transmission of vibrations from one structure to another, which is crucial in maintaining stability and image quality in filmmaking. By employing various methods and materials, vibration isolation minimizes the effects of external disturbances, ensuring that camera movements remain smooth and controlled. This technique is vital for enhancing the overall performance of camera rigging and mounting systems.
