I'm currently learning the proper use of sound blankets and other absorbing material on set to deal with reflections. So far I tend to use quite a lot in most locations I get to, thinking that you can always add reverb in post, but not take away what's already there. When moving the camera I often have to remove some of the added blankets, carpets etc out of the frame, and put it somewhere else.
Now, I have not had much experience of dialogue editing, but what little I had taught me that very little is needed to change the sound of a room. I was wondering if maybe moving around absorbers this way might cause some trouble for sound editors, or if the added intelligibility is worth it? Should you perhaps only use sound absorbers in places where you know they won't need to be moved during the course of the scene? In the end, maybe it doesn't matter, since repositioning the mics, lamps and people etc has a far greater effect.
Also, If I may cut in another absorption-related question, does anyone have any good tip on practical materials used to clean up low end on set? Is compact, thick matresses the best bet?
