Ciné film (sometimes Cine, no acute accent) is the term commonly used in the UK to refer to the 9.5 mm, 16 mm, 8 mm and Super 8 motion picture film formats used for home movies. It is not normally used to refer to professional formats such as 35 mm or 70 mm film, and is incorrect if applied to any video format. In the US, "movie film" is the common informal term for all formats and "motion picture film" the formal one.
Cine film literally means "moving" film; deriving from the Greek "kine" for motion; it also has roots in the Anglo-French word cinematograph, meaning moving picture.
Although there had been earlier attempts, typically employing larger formats, the introduction of the 9.5 mm and 16 mm formats in the early 1920s finally succeeded in introducing the practice of showing rented "play-at-home" copies of professionally made films, which, in the case of feature-length films, were usually much shortened from the originals.
More significantly, these new cine film gauges were the first truly practical formats for making casual amateur "home movies" of vacation trips, family gatherings, and important events such as weddings. Amateur dramas and comedies were sometimes filmed, usually just for fun and without any aspiration to artistic merit.
