Loudness LKFS Out of Spec

Description:

"Loudness LKFS Out of Spec" refers to an audio mix that does not conform to the overall loudness average specification.  M&E mixes do not need to adhere to this specification and should be excluded from measurement.

Impact:

Loudness Out of Spec impacts the Technical Quality of the asset. The asset does not meet the Netflix Delivery Specification. 

Severity Structure:

FYI

N/A

Issue

LKFS measurements are outside of BOTH the ITU-R bs. 1770-1 and 1770-3 specified parameters/ tolerances.

How to Prevent:
Monitor audio on timeline, and double check exports. Netflix uses Dolby Media Meter, Nugen LM Correct, or Baton Auto QC.  Please use the same tools to measure/ verify for consistency.                 

Solution:

Loudness must be adjusted to bring file into spec.  Lower or raise overall level average and re-export.
