The JVC GR-C1 VideoMovie was a camcorder released in March 1984 by JVC. It was notable as the second consumer-grade all-in-one camcorder after 1983 Sony Betamovie, as opposed to earlier portable systems in which the camera and recorder were separate units linked by a cable (portapaks), and as the first VHS-C camcorder.
