Corey,
The first thing you need to do is check what kind of mic your camera will handle. Look for things like impedance ratings. You'll probably have to purchase a mic that is designed for video cameras.
I didn't want to do this, meaning purchase another mic that would only be used on my video camera. So what I did was purchase an audio adapter for my video camera which allows me to use dynamic or condenser microphones with my video camera. I can also take line feeds from my Pro Tools rig and run it to the camera.
If you watch
DCTV as well as the
video lessons I've created here at the Drummer Cafe, you are seeing what my set-up can do.
The audio adapters range in price. I purchased a
BeachTeck DXA-4P for under $150 and works great ... and more importantly is compatible with my Canon GL1 video camera. If you go the audio adapter route, be sure that you find a unit that is compatible with your camera, plus good ratings and reviews by consumers. BeachTek is a reliable manufacture, but there are others.
Now I can use all my nice audio gear (i.e. mics, mic-pres, etc.) with my video camera.
If you decide to purchase an external microphone, you'll have to choose from a handheld, lapel or shotgun microphone. Each has their purpose as well as advantages and disadvantages. There is no one external mic that’s best for everyone, so you’ll have to do some research to find one that fits your needs and budget.
