What does MOS mean?
MOS stands for “Mit Out Sound” or “Motor Only Sync,” a filmmaking term used to describe shooting a scene without recording sound. MOS scenes are often used for visual sequences where dialogue or ambient sound is not needed, and sound effects, music, or voiceover can be added later in post-production. It allows for faster, more flexible shooting. Related terms include Sync Sound, which refers to sound recorded in sync with the visuals, and Looping, which replaces dialogue after filming.
Example:The director decided to shoot the action scene MOS to save time, knowing that all sound effects and music would be added in post-production.
Example: Many car chase scenes in films are shot MOS to avoid capturing unwanted engine or traffic noise, with sound being carefully crafted later.
