A shoulder rig is a camera support system designed to stabilize video footage while allowing for smooth movement. It typically consists of a frame that rests against the shoulder, with adjustable components to hold the camera and accessories. This setup helps reduce camera shake, making it easier for filmmakers to capture steady shots during handheld shooting. These rigs often include features like a padded shoulder pad, adjustable handles, and mounting points for additional equipment such as microphones or lights. Shoulder rigs are popular among filmmakers and videographers for their versatility and ability to enhance the quality of video production.
