The clapperboard is a unique device that has been used for decades in the film industry. It has been so widely seen it has become its own icon for this industry. But what does it do? Well the clapperboard is most useful in post production. When it snapped it leaves a sharp spike in the audio tracks of all the microphones and cameras and this can allow the editors to precisely synchronize the audio. More complex clapperboards will have detailed information about the scene and take and the timings. The editors then take and all that info that will help them piece together all the hours of film into a full feature film. The highlighted block in the image below shows the clapperboards spike in the audio.
