Global Sync Offset (Audio)
“Global Sync Offset” refers to audio across section or entire program that is out of sync (early or late) by a consistent amount of frames/ seconds.
Global sync offset impacts Technical and Content quality. At best, it will be distracting to the customer. At worst, it could ultimately make the content unwatchable.
Audio is 1 frame or less out of sync AND only for a single shot or short duration.
Audio is 2 frames or more out of sync OR 1 frame or less, but the global sync offset occurs through an entire scene or the entire program.
How to Prevent:
Review audio on timeline and ensure it is properly aligned with on-screen action, as sync can easily shift during an edit.
Verify that audio and video have been recorded at the same frame rate.
Fix sync on timeline and re-export audio as needed. Check the M&E for the same issue, and redeliver M&E as well if necessary.
