So upon reading all the great interviews and posts on BG creation/layering, im finally designing a specific set of backgrounds for a film. Im trying to make a background that can convey the harsh danger of a homeless girl living on the street. Its a series of 4 scripted scenes that in reality are one large flowing scene. There are 3 parts that are a stationary non moving and in the middle there is a long walk and talk steadi-cam shot covering about 8 blocks or so.
I currently have a hand-full of static stereo recordings I made in the neighborhood in which it was filmed.(I ended up being pretty uncomfortable there recording at night :P) I like them quite a bit, as one you can here a building alarm/buzzer in the distance, the other has a lone siren build up to many police/ambulance sirens and progressively get closer. There third is a general air with a single cricket going on.
I am planning on using train sounds in combination with the alarms and sirens to bring in the harshness and removing them to take away the danger at certain times that parallel the emotional arc Ive got going. BTW waiting for a train to come is a pain, I wish there would be published freight train schedules.
Any other ideas of things I can use to help convey the sense of danger?
Also during walk and talks, do you guys try and use backgrounds that were actually not recorded static. I was thinking about trying to record a couple stereo backgrounds while slowly moving down the street, or do you think having single effects like light buzzing or dogs ac units etc dopplering by would do enough to convey that movement? We are mixing in stereo for this project FYI.
Any help would be appreciated as I am almost done cutting all the dialogue and will jumping into the BGs very heavily in the next few days.
