Great audio starts in the field

You’ve probably heard it a thousand times before–viewers will forgive you for bad video, but they’ll bolt if forced to listen to bad audio. Wind noise and distorted audio hurts the ears.  Have a video where the subject can’t be heard over distracting ambient nosie? I, like most people, just hit the back button on my browser. Here are some audio tips I’ve learned from my time behind a video camera:

• I’ve watched too many videos and audio slideshows where wind noise has ruined an interview or mucked up the ambient sound. It is important to use a quality microphone with a windscreen to minimize this horrible sound. A couple of years ago, I climbed windy Mount St. Helens with my video camera. I bought one of those fuzzy windscreens that looks like a tribble (yes that is a Star Trek reference.) It worked brilliantly. For reporters stuck with a point and shoot cameras, good luck. Your audio is at risk every time the wind blows.
• If you use a lapel or wireless mic on a subject, the rule of thumb is to place it at the second button on a dress shirt. Don’t place the mic inside the shirt or against skin, as that will add a rustling noise every time the subject moves. Listen closely with headphones for noisy clothing like ski jackets or jingly jewelry. You will beat your head against your keyboard trying to edit around these distractions.
• Nothing screams amateur like a dangling mic cord on the outside of a subject’s clothing. Take the time and run it up inside the subject’s shirt or top. If it is a tee shirt, run the mic out the collar, and down a couple of inches. Pinch the shirt and clip the mic so that it is facing up. It doesn’t always look the best, but will give you better audio quality than if you just clipped it to the collar. Also, take charge of placing the mic. The subject usually has no clue of how to clip it correctly. Stringing it under their shirt, well, I’ll leave that to my subject.
• If you are using a wireless mic, make sure to turn off all cell phones near the transmitter and receiver. Our company’s smartphones interfere with our Sennheiser G-3 wireless kits. This random interference will happen only when the subject says something profound.
• When I shoot interviews with a wireless mic,  I record in two channels of audio ( I use a Sony XDCAM EX-1 with two XLR inputs.) One channel is the wireless mic and one channel is my on-camera shotgun microphone. That way if I get interference or distortion, I can use the other channel in a pinch. This has saved me countless times. This also works well for stories where you have one subject that you need to wire up. I have that channel always recording, even if I’m just shooting b-roll of something else. I can always drop that channel when I’m editing. Great things are said when the camera is not in the subjects face. Just remember to turn off the receiver if your subject heads to the restroom…
• Get a curly cord extension for your on-camera shotgun mic. That way when you do a quick on tripod interview with someone, you won’t have to stick the camera so close to his or her face. A TV news shooter once told me that sound falls, so place that shotgun mic about a foot out and below the subject’s mouth. In other words, let the sound fall into the mic.
• Always wear headphones to monitor your audio. Everybody that shoots video knows that, but not everyone does it. Nothing is worse then realizing you captured crappy audio and then having to spend way too much time trying to make lamb chops out of ground beef. Ok, I admit  it. I hate wearing headphones. Sometimes I get lazy, but one thing I don’t ever compromise on is wearing them during an interview. You can always fudge your b-roll audio by lowering levels, but rarely can you do this with your a-roll audio.
• If you’re doing an interview with a subject outside, turn them away from noise like traffic. Shotgun mics tend to amplify the noise from behind the subject.
• Nothing is worse than trying to edit a sequence with music playing in the background of several clips. The ambient music will jump around like a goldfish on a carpet. Which brings me to the first thing you should do when walking into a room you’re going to record in. Listen. Listen for hums, clock tics (my favorite), traffic noise, music etc. Try to minimize these distractions if you can.
• Record a minute of room tone. You’d be surprised at how handy it comes in when you’re editing. Need a bit of breathing room between two clips of someone speaking? Room tone to the rescue.
