Sync - Dialogue
Audio/Video sync is inconsistent throughout source i.e. some scenes are in sync and others are out of sync.
Intermittent sync issues could be caused by poor dubbing or localised edits/cuts, for example, in sync for the first 10 minutes then it goes out of sync entirely for the remainder of the program.
Attempt to identify a pattern in when the sync is good and bad. If it is unfixable then an alternate source free of the intermittent sync issues must be located. If you are unable to locate an alternate source, please contact your Netflix representative via Backlot.
