Tips for better audio in your videos
Labels: Video How To
CANON DIRECTIONAL STEREO MICROPHONE DM-100. Compatible with most Canon Vixia camcorders like the HV30, this shotgun- style mic attaches to the camcorder’s accessory shoe for cable-free operation.
If your camcorder has an external mic input or “active” accessory shoe, your audio options definitely increase.
There are three microphone traits that are commonly discussed:
1. How is the microphone mounted? The usual options are handheld, camera-mounted and lapel-mounted.
2. What is the coverage or directionality of the microphone? This refers to how the mic picks up sound coming from different directions. Some terms used are omnidirectional, bidirectional and shotgun.
3. Does the mic require power, either from a battery or from the camera? At first, the options may seem overwhelming; in reality, unless you purchase an expensive professional microphone, the first two traits are combined. For example, a camera-mounted microphone usually has a shotgun style of pickup; a handheld microphone has something closer to omnidirectional.
A lapel or lavaliere microphone is like a macro lens, getting close to your subject and minimizing distracting background noise. Lastly, a handheld mic is similar to a standard lens, useful in many situations as long as you place the microphone close to the subject. But to carry the lens analogy a little further, recognize that with a few exceptions, none of these microphones is a zoom—the pickup pattern doesn’t change.
Next, consider how a microphone is powered. Unless your camcorder is capable of powering a microphone (check your manual), you’ll need to stick with battery-powered mics or “dynamic” mics that don’t require power.
