Sound

• ideally you want sound to enhance your visual content
• you want it to match, not to be distracting

Production Sound

• sound recorded during production 

Sounds

• background sound
• hard effects (door slames, guns, etc) 
• foley - sound efffects recorded later to match up with images 
• what sound sounds like the action
• "mood sounds" / "design sound" 
• ie if the room had a lot of outside noise, try and record a few of room sound 
• effect libraries

Sync Sound

•   sound came after imag ein the develpment of film because there was no way to reliably synchoronise the recorded image and ound
• recorded at 2 different rates, the audio image slowly get further

On Board Mic

• easy, fast, less conspicious, no need to worry about sync
• lower sound quality, no directional control, can pick up camera motor sound, can pick up 60-cycle hum if running on AC

External Mic

• Better sound quality, mic can be positioned to record key sounds mic can move during shot, no need to sync
• mic is still tethered to camera, can only move so far (unless using wireless)

Seperate system 

• ulitme freedom of movement, best quality, best level control
• requires sync ing during editing process, takes extra time
• if using a separate system make sure the timebase is set to match your camcorders time base. Use a slate.

MIC

• LAV (lalliere) - small, sometimes wrieless, hidden on actor's boy - must be close enouhg to moth to hear, but not be seen. can pick up noises, like rustling of clothes
• Shotgun - large, usually mounted on a boom pole. must ensure mic is pointed in the right direction and not visible in the shot (cardioid or hyper-cardioid pattern)

• position mics as close to action as possible
• position the mic to not pick up unwanted noise- exploit the null
