Since the work on the sound design can take a lot of time, you should invest in the sound recording stage properly. Don’t waste the time of your sound designer on eliminating noises from the scene instead of working on more creative stuff for the scene.
The first step in film sound recording is reading the script. While you read the script, write down all the sounds that you hear in your head. If you are starting to have any ideas for ambience sounds, write them down too.
Look at your list and decide what the sounds you’ll need to record on location and what are the sounds you can record later on by yourself are.
When shooting on film, the sound can be recorded separately (double system)to a machine. It used to be only when filming with film, but nowadays we use it even for digital shooting. The major advance of the double system recording is that many good cameras don’t have the XLR connection you need to connect the mike. The single recording means recording directly into the camera.
You’ll need to decide which one will suit you best.
