If a lapel microphone connected to the line input of the camcorder were used when taping the scene, however, the source noise could be quite low. Noise reduction: When a camcorder is used outdoors with the actors distant from the microphone, the “source noise” may be very high, and to make matters worse the internal noise of the camcorder may be amplified to intrusive levels. There is a lag of about a second before any new setting has an audible effect, so you should make changes in small amounts then pause to check if there is an improvement. You can often further improve your results by adjusting the Noise reduction and Fine tuning parameters. The preset you choose provides the starting point from which the adaptive algorithm proceeds. The filter responds dynamically to the changing noise conditions within the clip. This advanced filter suppresses unwanted noise in any audio clip.
