Not sure, but I do know the first encode, the commentary audio was not in sync with the commentary video at all. Now that's in sync. The way I synced the game audio and commentary is that the commentary audio is late by 1-2 secs in the beginning, slowly becoming less until the middle of the video, and then becomes 1-2 secs early by the end of the run. Also, encoding this is a beast, may take 2-3 days.
