Making a film is all about layers. A good story has many layers and it’s your job as a producer/director to reveal those layers as you tell the story so it has depth. Audio for film also has layers, and that is never more true then when it comes to Foley. The art of sound. Here’s a behind the scenes look at how it’s done with veteran foley artist Gary Hecker
Always get good audio when recording your video. You should also get some ambient room noise to cover any gaps later, it works well under say a narration to add some depth to the sound. But there are times when you cannot capture the true sound of the scene, and that is where foley can help. Give it shot. Shoot some footage and then grab some props and try to replace the sounds. I’m sure you will find it’s not as easy as Gary Hecker makes it look.
