What is Film Editing?

Film editing is part of the creative post-production process of filmmaking. It involves combining a selection of shorts and creating a finished motion picture. Film editing is unique to cinema: it separates filmmaking from other art forms (such as photography, dance, writing and theatre). This technique is also referred to the 'Invisible Art' because it is well practised, therefore meaning that the audience watching is engaged in the film they are not aware of the editors work.

This picture is a film editing machine called a Steenbeck.
