This is as much an observation as it is a question:
I recently finished a corporate video shoot where all the talent had corporate wear on. By corporate wear I mean suits and ties. Much to my dismay, the suits, shirts and ties were all cheap stuff i.e. made primarily of polyesters and such like fabric. The lead character's shirt collars were so tight around his neck that hardly a baby flea could have snuck in. This guy also had a lot of stubble and chest hair! Another character was rather overweight and his shirts strained against his skin and he too had loads of chest hair. Wardrobe could not help me as the clothing was all the talents own. To top it all off there was a lot of physical movement required by all the characters involved!
Now, because it was a dramatized shoot, all lapels had to be hidden and as the clothing was all the talents own, I could not whip out my ball point pen solution as that would have required holes being made in said clothing!
From day 1 (it was a seven day shoot) I had issues with clothing rubbing on clothing, clothing rubbing on hair and stubble etc. I managed to avoid the rubs by either hiding the lapels just under the collar flap or inside the tie knot and through the use of gaffer tape, managed to minimize the clothing from rubbing too much!
At the end, I relied heavily on my boom sound to ensure good clean dialogue recordings. I guess that lapels remain a luxury and mostly will have problems with clothing sound due to the simply proximity of the mic to clothing items.
Now my questions: 1) What other innovative things could I have tried with the lapel mics to obtain a clean recording from them?
2) As I have relatively very little audio engineering post production experience, I would like to know from the pro's out there:
By using the boom track as master audio, could one then layer the lapel mic track in sync with the boom track and then by manipulating the levels of the lapel track, boost the dialogue whilst loosing the clothing rubbing sounds? The theory in my head says that the dialogue should become louder (the tracks in sync doubling each other) but because the rubbing is present only on one track, it should not itself become louder. Any comments?
