Hello Ryan and welcome to the Cow Audio Form.
You’ve heard some good ideas. Hopefully here are some more.
First, a shotgun is NOT the mic to use. It will pickup reflected sound. You need a supercardioid like a Schoeps CMC641 or Sennheiser MKH50.
Yes, lay down blankets and have talent stand on one if possible to catch the first bounce of floor reflections. You can also use C-stands with arms to hang other blankets just out of frame. Get as many as you can and try to form a 180 degree semicircular barrier around the front of the talent.
I don’t know what your lighting setup will be but hanging a 20’ x 20’ silk over the talent will damp sound from the walls and ceiling.
You could try a cardioid lav, but I get that you want to boom the shot.
OK, here goes. In the series “House Of Cards” they do a very neat trick. They don’t use lavs.
The stand ins come in for lighting. When lighting is done, the set is emptied of people. The camera rolls X number of frames with no one on the set.
Talent comes on set. The boom ops are also on set and in the shot. They roll, allowing the booms to get plenty close. At no point can the talent walk in front or behind the boomers. In post, they bring up that first footage of the empty set and use it to mask out the boomers. There was a question about tracking shots. The “House Of Cards” post team said they could handle that as well.
Other less technical fixes include, inflating small balloons with helium and letting them rise to the ceiling. With enough balloons, you can cover the ceiling and reduce sound bounce.
One solution will probably not work if the environment is live enough. You may need ALL OF THEM.
How’s that?
