Audio/Video Sync Outside Of Premiere
(Mac Studio M1 Max, Ventura 13.6.1, PP 2024 24.0.3)
I’ve noticed that the audio/video sync is slightly off (1-2 frames) when I watch my exported videos outside of Premiere. If I import the exported video back into Premiere, the sync in perfect. But when I watch the exported video in Quicktime, VLC, Windows Media Player, on a Mac, on a PC, the video is always slightly late. ProRes, h.264…doesn’t matter. Anyone else notice this? It’s been driving me nuts forever.

Sounds like you might be playing your computer audio through a different path than your Premiere audio. Are you using a DA for Premiere audio out? Premiere has audio delay settings for output for precisely this reason. You may have a natural video delay that Premiere is compensating for.

A good idea, but no. I do use a BM Ultra Studio to check color on an external monitor, but I don’t send audio to it. My audio leaves Premiere through the 1/8″ headphone jack of the Mac Studio, and goes to a pair of studio monitors. So when I view the exported video outside Premiere, there isn’t a change in audio chain.
When I search the net on this, I find nothing. Only people with massive audio drift caused by mixed/variable sample rates and stuff. What I’m seeing is more subtle…sync off 1-2 frames. Mostly I ignore it and my clients don’t mention it. But when I cut quickly to music, it becomes very apparent to me.
It blows my mind that when I pull the video back into Premiere, the sync is perfect…but it’s off EVERYWHERE else (Mac/Quicktime, PC/WindowsMediaPlayer, Vimeo, iPhone). Is this “normal”, but most people don’t notice it? I doubt it. I feel like I’m taking crazy pills.

Check the Mercury Playback audio offset. See screenshot.

I fiddled with that setting just to be sure…but that doesn’t affect the exported file, just the playback on my color monitor.

Just did some tests, and determined that the exported video is late by 1 frame (at 23.976fps) relative to the audio. Not a huge problem depending on the edit…but like I said, whenever I do fast cut-to-the-beat stuff, I notice it.
UPDATE:
More tests: Raw file in QuickTime is perfectly in sync. B<font face=”inherit”>ring the file into Premiere, change nothing, export it (file type doesn’t matter), video is 1 frame late </font>in QuickTime. Do the same process in Resolve, the exported file is NOT off by 1 frame in QuickTime. Huh?

I just updated from Premiere 24.0.3 to 24.2.1, and the problem might be fixed. More testing is required, but fingers crossed.

Nope. Not fixed. Am I crazy? How is it that no one else has noticed this?
