A camera slider is a filmmaking tool that allows smooth horizontal or vertical movement of a camera. It consists of a track and a platform that holds the camera, enabling it to glide along the track. This movement adds a professional touch to videos by creating dynamic shots, enhancing storytelling, and capturing scenes from different angles. Camera sliders come in various sizes and materials, catering to different filming needs. Some are manual, requiring the operator to push the camera along the track, while others are motorized for automated movement. They are commonly used in conjunction with other equipment like tripods and dollies for more complex shots.
