Unless you have your own Hollywood style crew with technicians for every specialty- camera, lighting, sound, script, makeup, grip etc..., you're more likely to be doing everything yourself on a shoestring budget. Have you ever gotten a great looking interview that shocked you with how mediocre or bad the sound was?

It might surprise you to know that professional soundmen don't listen to the content of the speaker so much. I've often asked a soundman, "Did you hear what he just said?" and the reply was, "huh?") Far from being asleep, the soundman was listening to the background for noise.

Why is Background Noise Such a Big Deal?

1. Background Noise is Exaggerated by Microphones

The human ear is a wonderful instrument. It picks up sound and sends it to the brain. The brain filters noise out and let's you concentrate on meaning. The camcorder doesn't have that kind of a brain.

2. Background Noise can Hurt Editing

If you have to cut a piece down, say from 20 minutes to 5, a noise suddenly disappears calling jarring attention to itself. Example- a loud jet passes overhead and trails out. But if you cut before it fades, it's suddenly silent.

Sounds to Pay Attention to When Picking a Location

1. Exterior Sounds

  • Airplanes
  • Gardeners with lawn equipment- most prevalent in suburban neighborhoods in good weather
  • Garbage Trucks on pickup day- try to find out when that is.
  • Crowds of onlookers- "Hey Can I be on Camera?"

2. Interior Sounds

  • Crowds, as above such as inside convention centers, malls etc.
  • Generators and Fans
  • Overhead Fluorescent Light Hum in an otherwise quiet room.

Tips To Get Clean Sounding Video Interviews

You're never in a sound vacuum- well almost if you are in a recording studio. You can minimize low constant noise, like pedestrian foot traffic or mechanical hum by microphone placement.:

1. Using an On-Camera Mic

If you have a microphone on the camera, place the camera as close as possible to the subject without crossing the forbidden wide angle closeup zone of distorted faces with long noses and big chins.

2. Using a Separate Lavalier Mic

If you run the cable to the camera, it is something that people could trip on. There are wireless transmitter/receivers you could use, but now you have a new possibility
of wireless interference noise to minitor.

Make sure you coach your subject no to tap their chest, or it will sound like a huge explosion. If this happens try to repeat the question.

3. Using Directional/Boom Mics Over a Subject

Hear This: Sound Advice for Better Quality Video Interviews boom mic1 200x130 This is more in the domain of the pros- don't consider this if you don't have a helper. It is a definite possible saftey hazard for tripping. I've also seen sitting subjects suddenly stand up and hit themselves on it! Remember the "bloopers" where you see the mic in the shot.

This happened more in the olden film days with "rackover" cameras (no full time viewing of the exact frame). Definitely not for run and gun shooting. In a controlled environment, it's another way to get the mic close to the subject without necessarily having the camera close.

4. Using Headphones

Pros often use the earmuff style that cancels everything except the "track". If you have someone else asking the questions, you could do this.  If not, use some headphones with silver dollar sized foam pads. This doesn't shut you completely off from the outside world.

If you've predetermined that you have the sound "under control", you can forgo the phone to keep intimacy with your subject. Some cameras have a little earphone on the camera, which can be helpful.

There you have it. You won't get complemented on good sound, but you'll certainly know if it is bad. Oh, and like the post movie trailer blurb- "remember to turn off the cell phones".

About our Guest Expert: Rick Robertson

Hear This: Sound Advice for Better Quality Video Interviews scan0095 The last name may sound familiar, and that's because Rick, is my father (Mark Robertson).  My dad, has more experience and knowledge about film-making than almost anyone - certainly more than anyone I know.  He has been a cinematographer and videographer longer than many of us have been alive.  He went to USC for his M.S. from the School of Cinema in 1968.

His resume is too long to go into here (and on IMDB - they only have a small portion), but some of the more noteworthy projects he was involved with include "This is Spinal Tap", "La Bamba", "Chuck Berry's Hail! Hail! Rock-'n'-Roll", "The Larry Sanders Show", "Michael Jackson's - the Making of Thriller", "Nova Science Now - SpaceShip One", and more recently, projects with Eric Clapton and Sheryl Crow.  His specialty and passion has been in handheld, documentary film-making.

    Can I add one? Don't film in any empty room (unless you have the proper sound equipment). It might seem cool to film in a loft or warehouse space, but the sound will be a big echo, and tough to fix in post-production.

      Great one Adriane. Thanks....

    Any mic recommendations to buy for iPhone 4 for shoots involving a small group of people? I want to get into mobile filmmaking this year!

    • http://www.reelseo.com/ Mark Robertson

      That is such a good question but I have no idea... :( Id love to know what you find out.

    • Ariane Fisher

      Did you consider a Zoom H4N? You could sync it later in Final Cut Pro.

      • http://www.facebook.com/people/Jack-Lane/568580257 Jack Lane

        I recently started to use a Zoom H4N for all my audio... I shoot a lot with the Canon 7D so I have to... A great complement to Zoom and any on board camera mic is the audio syncing software, Pluraleyes – http://www.singularsoftware.com/pluraleyes.html. Makes it a cinch.

        There is a video on my homepage of my site that I recently employed the Zoom for... Anyone can check it out if you're curious of audio quality – http://www.lanemp.com.

        • Ariane Fisher

          Jack, that video is fantastic; great integration of the motion graphics. Are you editing in FCP? Editing 7D footage is a "fun challenge" in FCP.

        • http://www.reelseo.com/author/grantastic/ Grant Crowell

          Jack, does Singular Software audio sync tool only work with Final Cut Pro like the specs on the page say? I'm wondering if so, if there are any other audio sync options for people like myself who just have Final Cut Express, or Telestream Screenflow.

        • Ariane Fisher

          Grant, out of curiosity, in what capacity would you need it for Screenflow? We use a USB mike, which gets ingested as the audio track right in Screenflow.

          Can you snap markers in FCE like you can in FCP? If so, you can do a makeshift clapboard (or just clap), mark the audio and video clips at the clap and snap them. Not as simple as PluralEyes, but works nonetheless.

        • http://www.reelseo.com/author/grantastic/ Grant Crowell

          Ariane, I'm thinking of a separate audio track from a professional digital device right up close to the sound source (like a speaker at an event), which I sync with the video from a camcorder that is shooting the scene from further away. (When I'm doing it myself, I have no wireless mic, but I'm usually able to place my digital recorder considerable closer to the source.

          I actually haven't worked with FCE, even though I have a copy of it. Most of my video editing work is in Screenflow. I have thought of using a clapper (or even manually clapping or some other visual/audio effect) when possible, but I've heard it still may not sync as well. But of course, it's better than not doing it.

        • Ariane Fisher

          Interesting, I've never thought of Screenflow as an editor. I used FCE for a few months and it is an excellent editor. For our purposes, the efficiencies gained from the upgrade to FC Studio made it a no-brainer. Additionally, with Studio you get Compressor, which is a better option for web encoding than a simple QT export. You're not exporting from Screenflow with QT X are you?

    Great tips. Folks often focus on lighting and the visual elements, forgetting that video is an audio medium as well - and bad sound is the #1 reason viewers will click away.

    • http://www.reelseo.com/ Mark Robertson

      So true... On that note however - do you guys have any research to that point or can you point us to some? That would make a great post as well I would think.

      • Russ_Somers

        We see clips with better audio having a better completion rate. We haven't, though, isolated it and tested it as a single variable. A 2009 study found that the audio drives viewer's perceptions of video quality. It's at http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5293330, but subscription's required.

        The guys behind ReelSocialMedia (hey, interesting name) see the same thing we do with viewers clicking away from videos with bad sound. I haven't seen them quantify it, but they reference it in places like their '17 Essential Tools' whitepaper at http://www.reelsocialmedia.com/2010/05/free-toolkit-the-17-essential-tools-you-need-to-produce-your-own-videos/
