Which item on set helps ensure audio and video are aligned by providing a cue?

• A. Reflector
• B. Lavalier microphone
• C. Shotgun microphone
• D. Clapperboard

Answer: (D)

Synchronizing audio and video relies on a clear cue that appears in both the picture and the sound. The clapperboard provides exactly that: when it’s snapped shut, you get a sharp, distinctive sound and a visible frame change. Editors can align the peak of the clap in the audio waveform with the moment the slate closes in the video, making it easy to line up multiple cameras and audio tracks precisely. The other items serve different on-set roles—reflectors shape lighting, while lavalier and shotgun mics capture audio but don’t supply a sync cue across devices.
