Episode 13 – Avoiding Bad Audio
Video November 30th, 2007How many videos and short movies are ruined every day from bad audio? People will forgive mediocre video. If it is slightly out of focus, handheld, dim lit or whatever. But they will hit the stop button, change the channel, or grit through their teeth with bad audio. How important is it? What do you pay for on a airplane flight? They give the picture away for free, without the audio you don’t have the story, the emotion, the mood. Maybe I’m just an audio engineer, but I enter my work in a lot of film challenges and man is it a challenge to sit through most of these movies because the other movie makers neglect the sound.
So you bought a cheap camcorder with a built in microphone? Is there anything you can do to make this situation better. I will show you a few really fundamental tricks, while featuring the bad audio moving toward the good.
If your camera has an 1/8″ input for a microphone, purchase a small stereo mic that will sit on the hot shoe. Even the $30 to $50 units will improve your audio quite a bit. Get that mic closer to the talent, with an extension. It’s the same kind of cable that a pair of headphones uses. Get a microphone stand and mount the mic above the talent’s head pointing the microphone at their mouth. Turn off the A/C and any really noisy appliances. Listen to the sound coming from the camera with headphones, make sure it sounds good.

Hey Chris, Great topic. Have you ever messed around with parabolic mics? Have you encountered many issues with room acoustics and the shotgun mic?
December 2nd, 2007 at 1:04 am
I would be interested in trying out parabolic microphones. I have used three different shotgun mics. Two from Sennheiser and the Audio Technica I have. The Sennheiser’s had a recurring problem of picking up lots of reflections from the opposite node of the super cardiod pattern. When pointed at the subject it would pick up the reflection of their voice bouncing off any surfaces the subject was facing. It seems that the ME-66 was the worst with this in my own experience. If you can tame the reflections in the room with blankets or acoustic foam (pricey) it would help it. My Audio Technica is less problematic.

Hey Chris,
I really enjoy your show. I’ve learned a great deal and can’t wait to see more.
Do you have any tips for improving audio on cameras that do not have the microphone jack?
December 5th, 2007 at 11:42 am
That’s a hard one. If you could zoom out as wide as possible and get close to the camera as possible. Maybe deaden the walls of the room if you are indoors with blankets or something like that it will help. Of course along with the other background suggestions. If you really want to get fancy you could record the audio also on a seperate device, like a digital portable recorder. I have a Zoom H4. You would have to sync up the 2 feeds after the fact and the fancy way is with a Slate board but you could just clap your hands on camera a couple of times and use that to sync to the audio claps. But now you’re spending money that could go to a fancier camera. Hope this helps.

I think I need a tripod next time if I use that cam!
This will definitely help people out on improving audio quality. Hearing how each step of the way changed on camera was bad but hearing it on speakers was far worse. It also reminds me of the refrigerator on Dave’s movie.
Can’t wait to see the next video!

Hey Chris,
Sorry i am a bit late to the party, but ya awsome podcast thanks soo much. Was wondering, have a panasonic PV GS 180 that has a mic import but no hot shoe, and no adjustable audio controls. Any recommendations for a mic?
Cheers.

Hi Andre,
I would try a small mic with a battery like the Sony Mic I show in the video.
This is the closest that I could find quickly, there may be cheaper units but this is similar to the one used. Sony-ECM-MS908C If you type it into Amazon or somewhere similar you should be able to find a selection. I hope that helps. All the old models have changed due to the Removal of Lead from most electronics in the past 3-4 years.

Thanks so much for the suggestion, seems like a really good fit for what i am looking for. I was also considering the Rode video shotgun mic, as i have heard amazingly positive things. However i heard it can be too sensitive for consumer mics, and as i mentioned before my Panasonic features no way of changing sound settings. Any possible suggestions?
Cheers again mate.

I found your site after looking up Teleprompter on youtube. I appreciate the links for the software by the way.
I noticed in this video on audio you mentioned some DIY lapel mics that you’ve made. Do you have a build list and schematics for those. I would really like to try that. Thanks in advance!

Hi Chris,
The other video with the lapel mic design is on my site also it is Episode 5 DIY microphone. Here’s the link.
