Audio glitches being added to mp4 exports

hi all -

im just trying to troubleshoot an issue we see commonly - flame 2024.2

all tech checks done on a file - 25fps timeline, no mistakes etc

mp4 export when checked back in QT - 2 frames of audio glitch added to the end of the file.

pro res export - no issues

any ideas what i should check next ?

thanks all

is this a known issue in 2024?

It is. If you export in the foreground it should be OK.

thanks! testing this now
