Headroom refers to the space above subjects in a video frame. Leaving headroom avoids cutting subjects off and mimics real-life perspective.
Always test equipment before shooting and check sound levels with a brief test. Get earphones to monitor audio quality while recording.
When shooting, avoid horseplay, follow schedules, cooperate with others, and listen as a team player.
Leave space beside subjects' faces as if drawing a dialogue box, and allow room for subjects to walk in order to get good footage.
Do not shake the camera, make background noises, or rough handle the camera while shooting to avoid poor quality footage.
Take notes while filming to help with editing order and story
