Since updateng from 2020 to 2021 our h264 exports have had audio issues in the quicktime player. It will play in the beginning but will go out of sync over time. Skipping forward in a video either stops the audio or throws it completely out of sync. We have tried a whole range of export settings for both the audio and video, turned off hardware accelaration, exported directly from premiere but nothing seems to effect the issue. Videos play fine in other players and videos we exported prior to updating play fine in quicktime.
@adobe Any help on this issue? Ive seen other threads here and on the premiere board with similar playback problems.
Same issue here; h.264 exports/transcodes from AME 15.1 and 15.2 have out-of-sync audio in Quicktime, Preview, Switch, and MacCaption. Audio plays fine in VLC. It seems to be especially bad when transcoding to interlaced h.264. AME 14.7 exports do not have this issue.
Did you guys have any fixes for this problem? I'm having the same issue and it freaking drives me mad. How could I fix this?
Reverting to AME 14.9 was my solution.
Glad to know others have been having this issue. I have to keep instructing clients to download VLC. They keep freaking out that something is wrong with the videos I send to them for proofing. It's really infuriating. Is it an Adobe issue? I assumed it was a problem with QuickTime...
Its kind of both in a way. I dont know a ton about back end of encoding but adobe seems to have changed something in their 2021 versions of both premiere and encoder. Videos exported prior to this work fine in quicktime. Whatever the change was VLC and other players seems are able to interpret it where as quicktime does not.
Unfortunately we deliver a lot of files directly to end viewers, many of whom struggle with technology. We need our videos to play on their system default player. We're having to run handbrake on a 2nd computer almost 24/7 until adobe fixes their issue or apple updates quicktime to interpret it.
