How to get good quality sound when shooting a film?

Q. When I always used to make short films I used the crappy camcorders Microphone, and it sounded so mono and just not filtered. What is the best, cheapest way to get Theatrical quality sound? Thanks.

A. Good question- people don't realize how much good sound counts, you can have crappy images and weird editing, but if the sound is messed up it will take the audience out of the story instantly.
Find a cheap shotgun mic ($40) that has an 1/8th plug for the little cameras, and make a cheap homemade boom-pole and windscreen. Have a friend be boom op.
Next step- post sound. 99% of all sound in professional films and videos is recorded in a studio, then edited in- even the dialogue. Use only the dialogue from your on set recordings- edit everything else out then either rerecord (foley) the ambient sounds- footsteps, rustling, birds, etc. in post or find free samples online. If the dialogue is messed up do ADR, or record the actors lines in the studio (a quiet closet) and sync them up. Mix and EQ.
Also don't forget to record room tone on set, its the ambient hum of every location- and it changes with every room or location. After you finish filming just record 30 sec. of absolute quiet- you can then insert that room tone to help smooth over your edits in post- that's how the pros do it.


What kind of external mic do I need?
Q. I have a Cannon ZR40 camcorder and I would like to have an external microphone of some sort for a movie that I'm shooting outside between two people. I want a better quality microphone when It comes to the sound interference outside that the camcorder microphone would pick up. Yet I'm not sure what kind I need. I'm trying to make a makeshift boom pole with the mic. What would I need that isn't too expensive?

A. There are two ways you can go...

1) a Shotgun mic can work well - but it presumes the two people are pretty close to each other. In addition to the mic and the boom pole, you probably want to use something like a Sabra SMM-1 universal shock mount... and a zeppelin (also known as a "dead cat"). Rykote makes a good one - but they are expensive. You may be able to make one. do a search for "zeppelin". Even if there is NO wind that you can feel outside, there is some wind. Since the distance of the mic cable will probably need to be over 15 feet, you want to use a shotgun mic that uses XLR (balanced) connectors and cabling. Since the ZR40 has a 1/8" jack, an XLR adapter will be needed - I would suggest something like those from BeachTek like the DXA-6vu. I don't know if the ZR40 has manual audio control - if not, then the DXA-6vu will provide it - if so, you might be able to get away with just a XLR-1/8" jack cable adapter. On the affordable side, NRG Reasearch makes a nice unit in the SA-568. Audio Technica makes several good ones... they can get expensive. Sennheisers are my favorite to work with.

2) A wireless lavaliere (clip on) on one or both people speaking would also work well and the mics can go under clothing (but not under heavy jackets). Shure and Sennheiser make good ones. They are expensive. You need to tape the mic to the person's chest (hidden) using moleskin or some other adhesive so their skin does not get torn off. And the body pack slides on a belt on their pants. The base stations can be either 1/8" or XLR, so whether you need the XLR adapter or cable will be dictated by the connectivity the base stations need.
