Hi Carlos,
Jason did an excellent job answering your question, but I’ve made a few audio recording errors and bad camera purchases in my days as a videographer and I just wanted to pass on some advice that I have learned by making mistakes.
First off, tapeless or miniDV? It used to be that most consumer-grade camcorders recorded to miniDV, but over the last 2 years, AVCHD camcorders have become more popular. The only round-about is that you have to find one that is both PC and MAC-compatible, or understand that if you’re editing on a MAC, then you need to do your research. This is a good article that compares which AVCHD camcorders are Mac-compatible and which aren’t.
BEST-RATED 2009 MAC-COMPATIBLE TAPELESS CAMCORDERS:
Under $400: Canon HG10 AVCHD High Definition Camcorder with Optical Image Stabilizer
Around $700: Canon VIXIA HG20 AVCHD 60 GB HDD Camcorder with 12x Optical Zoom
Around $1,000: Sony HDR-SR11 10.2-MP 60GB High Definition Hard Drive Handycam Camcorder with 12x Optical Image Stabilized Zoom
Once you have chosen WHAT camera to record video with, the next step is to decide HOW to record sound.
3 WAYS TO RECORD SOUND:
1. Wire the Subject: Lavalier Mic Method
If you’re going to record a dance lesson I suggest using a wireless lavelier mic only if you’re not moving that much. They pick up the sound of your clothes rustling and body movements which can also change the strength of the mic’s pickup. They also have some interference with other wireless devices like cell phones, and sometimes record sound intermittently. Here is an example of one of our author’s using a wireless lavelier HEADSET: http://www.mindbites.com/lesson/1247-full-ballet-class-drill It sounds great when it works, but if you notice sometimes his voice cuts off when he moves.
1. Boom Pole & Grip Method
Or you could do the professional approach: On movie sets they use shotgun mics connected to boom poles that someone holds 2 feet above/below the speaker. You would have to craft or purchase a boom pole and attach a shotgun mic to the end of it. You would also need a friend to help hold the boom pole; while a camera could just sit on a tripod, a boom pole would have to follow the speaker and remain the same distance away to get consistent sound.
3. Dub Audio Over Video Method
If you don’t have a friend or someone to help hold the boom pole and you know a wireless mic will not work, you could dub the audio over the dancing lesson like in this ballet video: http://www.mindbites.com/lesson/1254-the-ballet-barre-the-inevitable-ballet-basics Doing it this way becomes an additional step in the editing process, but you have more control over your audio and you don’t have to memorize it beforehand; you could just read a script and record.
Once you have chosen the method for which you want to record, you can choose a mic to purchase.
BEST 2009 CONSUMER-PRICED MICS:
1. Lavelier Mics
Wireless under $200: AZDEN WMS-PRO Lavaliere System with Hand-Held Microphone
Wired under $50: Olympus ME-15 Microphone
2. Shotgun Mics
Mounts on camera around $100: Rode VideoMic Directional Shotgun Mic w/Mount
Mounts on boom pole around $50: Audio Technica ATR-55 Condenser Shotgun Microphone
My ideal setup would be to have a Sony HDR-SR11 and an ATR-55 Condenser Shotgun Mic attached to a boom pole, but this limits those who want to shoot without additional assistance via a grip.
