Audio

 A good video's (or podcast's) basis is a good story. Good audio, combined with creative cinematography (link to podcast), and lighting (link to podcast) can make or break it becoming a great video.

In this section we will look at tips for good audio. Most of these audio video tips also apply to podcasts.

A. Preproduction - planning ahead (choosing the right mic, settings,etc.) 

Basic tips

  1. Make sure camcorder audio is set to 16bit (default is 12). Make sure the clock on the camcorder is set.
  2. Use a headphone to listen to what is actually being recorded. Try this before going out on a shoot.
  3. Use an external mic with that mic placed close to the sound - the sound will always be better. (It is possible to use the internal mic with limited success if you are very close to the speaker (~3') or just trying to capture ambient background sound.)
  4. For iMovie, make sure to use a mono to stereo adaptor (photo) if you are use mono mics, such as the sony wireless (photo of mic and photo of plug showing single and dual bands). Your camera is expecting a stereo signal - this adaptor allows your mono mic to be heard on both left and right channels.
  5. Use the right mic for the situation
  6. Practice using your equipment before going out on a "shoot"

Microphone Types (cardiod, omni, pattern, etc., mono (picture of stripes), phantom, etc.)

B. Production - Shooting techniques to improve your audio
While shooting there are some basic techniques you can use to impove your audio...

  1. Look at previous section for correct mic choices. Test your equipment before shooting.
  2. In general, have mic as close to the talent as possible (except for distorting) without being in the shot.
  3. If using a wireless mic, be aware of things that might rub up against the mic. Not good for shots where talent is moving.
  4. Use a headphone to monitor your audio.
  5. Boom mic location options - 1) top, 2) side, 3) facing up (link to diagram)

C. Post Production - importing and manipulating audio in the computer
After the footage is in the camera, you can adjust the audio levels so that the sound is more smooth (level). You can also add external sounds (sound effect or music).

  1. On the computer that you will be editing with, set a system volume level that you can aim for and keep it there (attachment w/ screen shots)

Resources

  1. Converting sound files for use in digital video (PDF) —it's more than just grabbing it from iTunes
  2. GarageBand 3 Sound Effects & Stingers - a screenshot list w/ categories and time
  3. FreePlay Music - We have a district license to use this music in most projects, including projects for entry in contests. Bring your external HD to the district library and copy these >7GB of instrumental songs onto it.

A little view of FreePlay Music - each folder contains many songs of a variety of lengths. There are 3 volumes so far, Vol. 1 (red), Vol. 2 (orange), and Vol. 3 (green).
