When recording video it is crucial to capture audio in the clearest way possible. Often the built-in microphone on a camcorder is not sufficient to capture high-quality audio from the scene. The use of an external microphone is highly recommended for all high-quality video recording. There are a number of ways to capture audio using non-built-in devices, these include:
An external microphone connected directly to the video camera. This can take the form of a boom microphone or a 'shotgun' microphone attached to the hotshoe mount of the camera.
An external microphone connected to an independent audio recorder
Built-in microphones on independent audio recorder
No matter what device you use to do audio recordings, you should use these settings:
Using a Zoom H4n Digital Recorder
Record in MONO unless there is a good reason to do Stereo (use stereo for performances with more than one performer and MONO for interviews and songs sung only by one person)
USE WAV Format Only
Bitrate:
For sound that will never accompany Video:
