microphone for filming choir/band concerts
We film a lot of middle and elementary school choir and band concerts, create DVDs for the parents. As of now, we just use the audio that we get from the 3 inexpensive mini dv cameras we shoot with. The results are actually pretty good, especially if the soloists are playing into a mic from the house sound. In general, nothing else is mic'ed just the wonderful sound you get inside a gymnasium that is used for the concerts. My question is this. Is there a microphone that I could connect to one of my cameras, maybe run it up to the front and get better audio? I have heard that there are flat mics that are made for this but have no experience with them. Or, should I just be happy with the results I am getting with the inexpensive mini dv and its built in mic. Thanks so much in advance for your expert advice.
