We’ve been made aware that there is an issue with exporting subtitled videos on iOS 18 only —where the video may be incorrectly exported without any subtitles.
This happens if your subtitle script ends before the end of the video i.e. there is a subtitle gap at the end. We’re trying to find a workaround for this currently, but for now the fix is to not have a gap at the end or use iOS 17.x.
We know it sucks, sorry. We’re trying to unpick what changed in iOS to cause this!
