To what purpose? Attaching a mic on the camera is pretty much guaranteeing yourself the worst audio you could imagine; putting a better quality mic on there is going to amount to putting a band-aid over open-heart surgery.
You'd be infinitely better off to get a microphone off the camera and over to where your subject is.
If that's impossible, well, do what you gotta do but just understand that your audio is going to stink -- specifically because the mic is on the camera, which means that it's a long way away from the speaker.
and you might want to check in the audio forums stickies for mic suggestions... Barry's spot on (as usual) with his reccomendation to get the mic off the camera though.
What is the best way to use the HVX when you are on the go and need to shoot video while moving quickly, in a scenario where you are taping events as they occur? This is why I was thinking of a better on-board mic.
boom pole with boom op, with wireless lavs as a backup would be ideal to me, but I would take either over a camera mounted mic, if both was not feasible for one reason or another.
a good quality xlr (canare star quad for example) can easily go over 100ft in normal conditions (working near giant antennas, and high tension power can induce interference). Not sure what the actual upper limit is though. Never needed more than 100ft...
Distance is the key thing here. I have gotten excellent audio with a quality shotgun mounted to the camera. Some of the factors: A] the HVX has a nice
insulated mount for the external mic B) when in P2 mode, the camera has almost no noise to filter into the audio , and C) a typical shotgun will extend nearly a foot past the lens. So you could interview someone at a distance of 3 feet and they would be only 24" from the mic.
I would agree that when shooting someone more than about 4 feet away,
get the mic on a boom.
If true run and gun sit, if you can RENT a few mics before hand and similate your situation, then figure out what works best for you ....maybe also you can think about a wireless setup that would work....
A VERY impressive mic for the purposes you describe. Mine is mounted on my HVX. Very directional, like a laser beam. I recently recored a memorial service where prancing around wasn't so respectful. My farthest speaker was about 70 feet away and the audio was great. I even had speakers that weren't even facing me and their speech was clear and usable. Worth the $650 if you work as a "one man band".
im looking at the shure vp88. from what i gather its a very distinct mic and has both a very good noise floor and max pressure. making it a great all around live / location mic.
