Last weekend, I taped two video footage by Canon XA20, one was interview in the boardroom and the other was academic presentation in classroom, with sennheiser ew100 clip-on lavalier to pick up voice . I didn't hear anything wrong from the headphone during video recording. The audio was good when playing back on computer. However, I could hear low noise behind the speech or talk. The noise is like low frequency "wuuuu, wuuuu" through out the whole footage. At first, I guessed it was caused by air duct central air conditioning but later I found out there was no such thing in the room.
Did I do something wrong ? or the input level on camera was too high ?
How can I remove noise from the footage ? I use PE12 to edit video.
