Noob question for sure.

 

Exporting my first 5.1 mix in STP and I'm confused by the Dialog Normalization field setting. STP manual states "For example, if the dialogue in your project averages around -12 dB on the level meter, enter -12 in the Dialog Normalization field."

 

Then it says "If you enter -31 dBFS, the attenuation is 0 dB (31 dBFS–31 dBFS), and the source audio levels are not affected at all."

 

How can both be right? If my dialog (Center Channel) averages around -12, do I enter -12 or -31 into the Dialog Normalization field?

 

One other note that is potentially the reason for my dilemma. This show will be screened from blu ray or DVD in a theater. I sent out test discs last week and the projectionist said his board was reading -39. Is this because Normalization was set to -31 for that mix? Did I just answer my own question?

    Export from STP with the levels that you want on playback from the system. If you want peak level at -12db, that's what to export.

     

    The -31 comes into play when you are building the DVD. There is a setting in the audio tab of the ac3 DVD preset in Compressor where you can specifiy the Dialog Normalization level. -31dbFS will pass the levels you set in FCP on through to the DVD.

     

    I don't deal with Blu-Ray, so can offer no advice there.

     

    Good luck.

    Thanks for the reply. I'm exporting the AC3 directly from STP.

     

    My confusion is why the STP manual says "if the dialogue in your project averages around -12 dB on the level meter, enter -12 in the Dialog Normalization field." then says "If you enter -31 dBFS (in the Dialog Normalization field), the attenuation is 0 dB (31 dBFS–31 dBFS), and the source audio levels are not affected at all."
