Film Clapperboard with MOS Day/Nite Marking - Production Tool Guide #106565 (License: Personal Use)

This black-and-white clapperboard features standard fields for roll, scene, take, director, camera, and date-with “MOS DAY NITE” handwritten in the date section, signifying a silent (MOS = Mit Out Sound) shot filmed either during daytime or nighttime. The hinged clapper arm is open, ready to snap shut to mark sync points for editing. Widely used in film and TV production, it ensures continuity and timecode alignment across shots.

Used on-set during filming to identify scenes, takes, and technical metadata; especially relevant when shooting MOS (silent) sequences where audio is not recorded. Matches user intent for film production resources, educational content on cinematography, or equipment reference guides.
