Most camcorders have on-board sound recorders, in most cases, the microphone will be omnidirectional meaning that it captures sound from all directions, however, unlike a human's ears, they cannot filter out what one does not want to hear. They often pick up and amplify even the smallest of the operator's noises.
When filming, what sounds do you need to take most care with?
- Silence; to be achieved properly, even the camera operator must be especially careful as the microphones are often more sensitive than most people may think.
- Finger noise (from the camera operator most commonly), this can result in a nasty muffled noise, it can be avoided by thoroughly learning the location of the camera's controls to avoid making noise near the microphone.
- Breathing; heavy breathing is not only heard through the microphone, but may cause camera shake, gentle and controlled breathing from the camera operator can minimize these effects.
- A Flapping lens cap is common, it is often the answer for an unknown tapping noise on a camera user's footage.
- Wind gusts can ruin the footage's other sounds, it can be avoided by a camera's wind reducer mode, in windy conditions, it will guard against a blustery tinnitus-inducing soundtrack.
- Hums and buzzes; the most common reason for this is the camera picking up on nearby electrical equipment, the simple answer to resolving this is turning the equipment off.
