Videographer Justin Brown from video editing coach did a useful quick tutorial last year on a way to hide a lavalier microphone under clothing in a way that will also help you avoid wind noise.
Wind noise in videos is a well known problem which almost anybody who filmed more than a few times outside ran into (and yes our videos are not free of this problem) . There are a few way to reduce this problem and Brown shows one option (he didn’t invent it if you were wondering and many sound experts have used it for years).
The concept is simple – take two pieces of gaffer tape and create small triangles with the sticky part outside. Put your lavalier mic inside the two with just a small margin so that the lavalier will be a little bit inside but with an open front. Attach this whole thing to the chest of your talent (or if he/she doesn’t like gaffer tape on their skin you can put another gaffer tape on the side close to the body to block it and just attach it to the inside of the shirt – just make sure it wont be too thick to be noticed.
We have looked at many aspects of using lavalier microphones in the past including using the Invisible Mic, how to hide the Invisible Mic (plus some cool tips for hiding mics) and which Lav mic sounds best? under $200.
On LensVid we have a very extensive section devoted to sound recording for video productions which covers both equipment and techniques here on LensVid.
