I haven't found it. And no debug info either.
Exporting directly from Premiere is a good idea right? Pretty sure I read on here that it works a little better than through AME? If I just have a single thing to render I usually do it our of Premiere. Other wise if I have a few things I send them to AME and then let it run when I am done for the day.
Some export formats are way faster using direct export instead of the queue.
