* '''Use headphones. Good ones.''' Headphones will show up a lot of audio problems early on - hissing, buzzing, bad microphone placement etc. Check your levels with headphones ''before'' you record. | * '''Use headphones.

* '''Check your levels.''' Assuming you're using Manual levels, of course. (Auto is easier, but won't sound as good.) Getting the volume right is a balancing trick. You don't want the levels to hit maximum ''at all'' because the sound will clip and distort in the most horrible way known to man. Similarly, you don't want them set too low or background noise will start to creep in (there's always some noise, but you want to keep your signal level fairy high above that). Avoiding clipping is your priority though; setting them too low isn't a great worry. | * '''Check your levels.''' Assuming you're using Manual levels, of course.

* '''Rifle mic''' - Also known as the boom mic, it's the long thin one with the fluffy thing. It's very directional, so it needs to be 'pointed' at the sound source - but used properly it gives nice, clear audio. The aforementioned fluffy appendage is a wind shield - it's a must when filming outdoors and a must-not when filming indoors. The rifle mic requires a single AA battery to power it, there is small a switch on the mic which just filters out low frequencies. '''The rifle mic must never, ever, ever, EVER appear in shot!'''. This has happened before and was hateful to fix in post. It can be done, but takes months of work. | |||
If you have a presenter that looks like they should be holding something, give them a handheld mic instead. The rifle mic has some friends: | |||
** Boom pole - a long pole to help you get the rifle mic into odd situations (ideally you want it above the scene pointing down). | ** Boom pole - a long pole to help you get the rifle mic into odd situations (ideally you want it above the scene pointing down). | ||
** Rubber mount - it connects the mic to the pole. The rubber absorbs any vibrations in the pole as you move it, which the mic would've picked up quite clearly. | ** Rubber mount - it connects the mic to the pole.

If you're a presenter interviewing someone and you're taking turns speaking into the mic, ''wait until you've fully pointed the mic back at you before you start speaking''. It won't magically pick up a clear recording of your voice just because you're holding it; it needs to be 'pointed' the right way. | If you're a presenter interviewing someone and you're taking turns speaking into the mic, ''wait until you've fully pointed the mic back at you before you start speaking''.
