At least H254 and H265 exports has this issue. On long exports over 60 min Audio is clearly out of sync.

 

With QT ProPres exports seems to be OK.

 

Tested with 1080P50 footage and export.

 

Please fix this issue ASAP.

@jt1972 I'm not seeing this happen on my end. I created a 66 minute timeline and exported it and there was no sync drift. I then took that exported 66 min clip into a new timeline and exported it again, in case the problem is with long clips. I also see no sync drift in that export.

 

Could you tell me what kind of footage and audio formats you're using? A screenshot of your timeline or sending a copy of your project (without media) could also help get to the bottom of this. Thanks!
