Audio syncing issue with H.264 exports - Adobe Support ...

All the audio and video is perfectly synced in my timeline and plays back fine. When I export with the high bit rate H.264 profile in Premiere (with match settings), the resulting file starts in sync but gets out of audio sync by the end of the file when played back on quicktime. However, the same output file stays in sync played through VLC.

I recently had the same issue with my h.264 audio going out of sync. The audio is also muted in certain places too. I do have mixed media including gifs and screen recordings. But this is the FIRST project I've ever had this audio sync issue with.
Audio Sync problem with EE4 H.264 output

I have a problem with EE4 when producing an H.264 encoded MP4 file from a DV25 coded AVI file, the audio is significantly out of sync with the video. Targeting WMV from the same source works fine. Encoding to H.264 using the open source program 'Handbrake' also works fine (their de-interlacing is arguably better as well!)

It is trying to convert a subtitle (#0.1) into audio. Try to select 7 as audio track. I'll add more option to detect the audio streams. In the meantime, use VOBs with a single audio track and no subtitles, or use VIDEO_TS. Quote 3rd Sep 2005 18:38 #7 Metallirat Member Jan 2003

Re: H.264 Pro Recorder audio out of sync. I've learned the hard way that the H.264 Pro Recorder (like most Blackmagic video capture hardware) requires a rock-solid video sync in order to capture and convert an incoming signal reliably. I had bad experiences with this device until I routed all off-tape outputs through a broadcast grade TBC (Time ...
Having a problem with audio sync in x264 conversions ...

One common cause of sync problems when converting video is a variable frame rate in the source. The encoding program often assumes constant frame rate and you end up with audio that gets out of sync. It wasn't clear to me if the MediaInfo report you provided in the first post was of the source or a file you made from it.
h.264 - Can .h264 container contain audio tracks? - Stack ...
https://stackoverflow.com/questions/1884101/can-h264-container-contain-audio-tracks
A container for video encoded with H.264 - such as an MKV or MP4 - can absolutely contain audio. That's how you can watch an H.264 video that has sound as well. On the other hand, it sounds like you could be confused about what H.264 actually is. H.264/MPEG-4 AVC is a standard for video compression, which has nothing to do with audio at all.
