MP3 vs AAC vs FLAC vs CD—READ THIS!
(If you have problems in Firefox use Internet Explorer)
Sound can be extracted from CDs using (partial listing):
A) Sound Forge
B) Windows media Player in the WMA format and possibly .wav
C) Real Player v.10 in the MP3,WAV,WMA, RealAudio format
D) iTUNES in MP3 etc. Format
F) Adobe Audition
G) Nero (programs within the suite)
1.) Please do not use Rock, R&B, Dance, Country, etc. music unless you can PROVE it is your own.
2.) I don’t care if you “borrow” audio from Classical, or New Age Composers.
3.) You can take TV or Motion Picture soundtrack audio as long as it’s not obvious. e.g. theme music from Star Wars, Lord of the Rings, Platoon, etc. Also see 1.)
4.) The best audio format to use in Premiere is: .wav because it is uncompressed. Convert .mp3, .wma etc. to the .wav format if possible. This does dramatically increase file size.
5.) Sound effect CD’s can be purchased cheaply at various music stores, or they can be found online for free or purchase. Do a Google search for “sound effects”
6.) Sound effects are located on the Network “S” drive (copy those needed to your folder on the “D” drive)
–DO NOT IMPORT THEM DIRECTLY FROM THE “S” DRIVE–
1.) If you are shooting outdoors, check your camera for a “Wind or Windscreen setting”, and turn it on.
2.) If you are recording sound, monitor the levels with Headphones.
3.) Avoid shooting dialogue with TV, stereo, or other sounds in background.
4.) Record several minutes of “ambient audio” at every shooting location. Use your video camera or a portable sound recorder, such as a MiniDisc, or DAT recorder with a microphone input.
5.) Avoid “up-down-up-down” audio sampling
6.) Avoid using audio compression schemes. In Premiere Pro under Audio Export, the compressor should be set to: Uncompressed
7.) Set your audio record settings on your camera to 48 kHz (DAT quality) if possible, otherwise 44.1 kHz (CD quality). The higher the setting (sampling rate) the higher the sound quality.
8.) The cameras electronic zoom (if used during dialogue) is sometimes audible in the background. If you have manual zoom capabilities use it.
9.) Use the manual audio levels on your camera if you have them.
1.) Dynamic = Employs a strong magnet and diaphragm, NO POWER source required, very sturdy mics, but usually lower sound quality than condenser
2.) Condenser (capacitor or electrostatic) = requires power from a mic battery or from the recorder
Microphone Pick-up (reception) Patterns
1.) Omni-directional or non-directional = picks up sound from every direction
2.) Uni-directional 9 (semi) or Cardioid (super) = heart shaped pattern
3.) Ultra-directional or Shotgun (Hyper Cardioid) = narrow cone pattern
4.) Parabolic or Hyper Cardioid (vomit mic) = extremely narrow degree of reception often used for recording at a distance
5.) Lavalier or chest mic = only purpose is to record speaking voice
6.) Bi-directional = figure eight pattern
2.) 1/4” phone,
