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.
