Audio is one of those things that you have to have for your movie but don't want to really think
about. You want it to just magically happen and let's face it, nothing in filmmaking happens
"magically". It might look that way but it doesn't. What you need is a good audiophile,
somebody that loves to hold a boom with a microphone on the end of it.
You can look for someone talented with sound or you can figure it out yourself. I suggest that
you get at least 2 decent remote mics that sync with your camera. While your camera may
have sound it is usually really bad. The remote mics can be worn on the body of the actor.
These will work adequately but proper mic placement it necessary.
