Error Code:

Audio Level Shift/Level Change 


Any abrupt change of base or peak audio levels that could be considered unintentional.


Level Change impacts the Content Quality of the asset. Member experience will be negatively affected if the dialogue level drops below an audible level. If audio levels rise abruptly, it may take the member out of the seamless viewing experience. In some cases, may be creative intent on the part of the content producer. 

Severity Structure:


Level shift is indiscernible in playback or can reasonably be attributed to the creative intent of the scene.


Level shift happens abruptly on a cut or audio levels are very noticeably different from their previous level.

How to Prevent:

Monitor audio on timeline, and double check exports. Netflix will use Dolby Media Meter, Nugen LM Correct, or Baton Auto QC to check levels. Please use the same tools to measure/verify for consistency.  Review audio at cuts for any induced fluctuations in levels.                           


Re-adjust the base audio levels so there are no abrupt changes. Check the M&E for the same issue, and redeliver M&E as well if necessary.
