This question was a bit hard to search for... what is the recommended audio range to keep my project within if I am making a short film which I plan to export to DVD.
As of now, a lot of my audio stays between -30 and -18, even if I turn it up all the way in each clip. Is it a problem if I add the "Boost" effect to every single audio clip I have? Or is there a quicker way to turn up the audio (Master volume is already at 100%)
I shoot for about -6dB, with no peaks above 0dB.
Sounds like you have a very weak signal. I'd set away from PrPro and handle this in SB, or Audition. Listen carefully with a good pair of noise-canceling headphones first, and then test on monitors.
Are you working in mono, stereo or 5.1 SS?
