When creating a composition for use with DV material, mix the audio to “12 db. If going to digi-beta, then “18 or “20 db. But don't forget that music and sound effects on Audio CDs are usually mixed to “0db. (Yes we meant to say minus before the zero. That's because music CDs are mixed and compressed so they sound nice and loud in your car; they peak right below Zero db.)
Whenever you use music from a CD, remember to pull its levels down so they hit the appropriate ( “12 or “20db) target levels.
