The origin of the clapperboard:

Movie history first block clapperboard inventors may be Frank Waslin (FrankThring)， he served as Australia Eftee Melbourne film studio in the last century 20's supervisor. The film is composed of many shots， each film generally havehundreds or even thousands of lens， movie， the content is very complex. The filmis not carried out in accordance with the order of the plot， but at the scene， such as the first location play， take studio in play， or the first summer drama， thenwinter play， and even the same winter scene， some of the plot is the story set in the front， and some of the plot is in behind the. In order to ensure the quality，some shots and shot several times. Hard to beat a few months back， a lot of film，how to put it into a full-length movie? If there is no obvious marking film， will bringgreat trouble to the editing work.
