Export settings are as follows:
Render setting – Best Settings, Frame Rate 29.97
Output Module – Quicktime, RGB etc, Format is H.264, Audio is 48000Hz
Last time it was moments away from being complete (after 4 hours..) and then stopped, saying there was an output module incompatible with the files (or something along those lines). I went to output modules in the templates, and deleted the missing module (mutli-machine).
