Comment (by aLPHa_NRG):

 ''I understand what you are saying and aboutg the frame rate you are
 right. But the reason I raised this ticket is that the audio is out of
 sync. And this sounds to me to most viable reason. I can not think of
 anything else that could cause this issue to appear ...''

 ''Here is the additional info I promised.''
 ''Framerate from the original ffmpeg file before conversion:''
