The term "MOS" is used, on a slate, when a scene is filmed without sync sound (or any sound). This directive is widely thought to be a homage to Lubitsch who would say, in his thick Berlin accent, that he wished to shoot some footage "mitout sound." "Mit" means "with" in German...ergo...without sound..."mitout sound"- "M-O-S."

Over the years film directors sometimes shoot particular footage silently, without the use of a live microphone. It is known in the industry as shooting "MOS." The origin of who and where it was coined maybe lost in the mists of time but we do know that it was homage to Lubitsch who used to say, in his thick Berlin accent.. "Let's shoot this one 'mit' out sound." Without sound. 'MOS.'
