I respectfully disagree with Tom.
I don’t use a mixer at events…I’m too busy shooting to worry about setting audio levels in response to changing conditions. If you have a separate audio person to handle it, then live audio mixing becomes more practical.
I don’t have an audio guy, so instead, I capture audio from multiple sources and mix them in post, when I’ve got more time.
The iRiver iFP series will produce excellent sound, quite acceptable for wedding video. However, you must use an external microphone, such as the lavaliers made especially for them by Giant Squid. The built in mic is only good for verbal notes to yourself.
The problem with on-camera mics is that they are almost never close enough to the sound source to get good audio…hence the “echoey” quality you complain of. You have to get a mic right up to within 2 feet or so of whatever audio you want to record.
An iRiver, minidisc recorder, or a wireless mic, with a lavalier mic element, can be placed on the groom to capture the vows. Sometimes, you can also get the officiant to wear a mic. A backup mic can often be hidden in a flower arrangement near the altar. You can place mics at the pulpit, the reader’s lectern, and in the choir loft.
If you shoot with two cameras, you have four audio tracks to route your mic inputs to. If you use a Canon XL-1 or -2, you have up to eight. All of these tracks are, of course, automatically synced to the video, saving you time in post. Audio recorded by MP3 recorders or minidisc has to be separately captured and synced.
Sometimes you can get a good audio feed from the church’s sound board. I prefer to use my own mics, because you never know whether the church sound person knows what they’re doing (and some don’t want you tapping into their gear). Still, I always carry a box of audio adapters. I can plug into XLR, 1/4″ mono, 1/4″ stereo, or 1.8″ mini jacks, and adapt them to my wireless or camcorder inputs. I can also insert an audio “pad” or attenuator, to reduce a line level output from a mixing board to a mic level signal for the camera. All of this stuff will cost you about $50 at Radio Shack.
No matter what method you use, if the church sound system has problems like feedback squealing, rest assured that you will be blamed for it. 🙂
