Info LUFS for cinema
Posted: Sat May 29, 2021 7:52 pm
Hello everyone,
first of all, thank you for this magnificent software: it is literally magic.
I am writing you after reading several other threads here, because I'd want to be sure about what I'm doing in Dpc-o-matic.
I'm trying to make a DCP for my shortfilm in order to present it at film festivals, but I have some doubts about audio settings, in particular loudness. I read that a good compromise would be to have integrative loudness around -20 LUFS (mine is -21 LUFS, as you can see in the first image attached).
But analyzing the audio track with a loudness meter (as you can you see in the second image attached) at some points it shows a momentary max LUFS of -15.2. Would it be a problem? Will these very short peaks be too loud in a cinema theatre? Or does the "critical" value of -14 LUFS refer only to the integrative loudness and not to momentary max one?
Another question: is there also a minimal critical value of loudness in order to listen also a quiet ambient track? In the graphs attached there are several fragments where LUFS are around -45. Are these too quiet?
I do want to say that in the audio track there are no dialogues. It is all an immersive combination of suspended sounds and music, except for the last fragment where there is only a forest ambient.
Thanks in advance to those who will help me!
