Which microphone is best for close-up dialogue when the actor can move freely?

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

Answer: (A)

The main idea is choosing a microphone that stays consistently close to the voice as the actor moves. A lavalier microphone fits this perfectly because it’s clipped to the actor’s clothing near the mouth. This keeps the pickup at a steady distance, giving a clear, intimate sound with minimal changes in level as the actor shifts position or tilts their head. It also helps reduce room ambience and is discreet on camera, which is ideal for close-up dialogue where movement is allowed.

Reflector and clapperboard aren’t microphones at all—one is a lighting tool and the other a video cueing tool—so they don’t capture dialogue. A shotgun microphone is highly directional and works well when you can place it off-camera, but it’s sensitive to distance and angle; any movement can cause volume and tonal changes and it’s more likely to pick up room noise. Lavalier, by being tied to the actor, delivers consistent sound for close-up dialogue with movement.
