Quicktime not able to sync audio when playing h.264 exported from adobe

Hi! I'm curious if anyone else is having this issue. When I export an h.264 video from adobe premiere or adobe media encoder QuickTime has a hard time keeping the audio in sync. It will start in sync but any time I scrub the video the audio goes way out of sync. When I play the same video in other players like chrome or adobe bridge it plays back just fine BUT if I export the video in other NLEs like divinci resolve or iMovie, QuickTime seems to be okay with those. Where is the issue and how do I fix it? Is it with adobe or apple or are they just not playing well together? Thanks!

Hi all,

I was having the same problem with taking an older QT or h264 mp4 video file, converting it to a smaller H264 mp4 video file using Media Encoder 2021 on my iMac and then getting a mp4 file that was out of sync when playing on Quicktime Player. I looked up a few things and did these things:

cleared Media Cache in Encoder
did a VBR 2-pass under the instead of the default 1-pass user the Video tab Bitrate settings

Then the video that it output played in sync on Quicktime Player. I have a 2020 27 inch iMac running Catalina OS. Hope that helps someone out there...

This is not okay. I just bought a new MacBookPro for video editing. I use Premiere. My exported videos play back out of sync in Quicktime. So why did I spend $3500 on an Apple computer? Not very confidence-inspiring.

Will Apple ever be addressing this? The initial post was 10 months ago. At least can Apple tell us where to download Quicktime 10.4 if 10.5 has a bug?

Will Quicktime 10.4 work with macOS Big Sur? Where is it downloadable? I've looked and can't seem to find it anywhere.

Thanks Dave and Matti! Just gave feedback, will continue to shout into the void, maybe on social media too for good measure.

I do hope this gets figured out, and that Apple is paying attention - it's a waste of time to have to playback elsewhere as a workaround.
