Some specs would help. Are you using CC or CC 2014? Or older? OS? Exporting directly from Premiere or through Media Encoder? et cetera et cetera.
There are a few general tricks to get rid of the dreaded “error compiling movie” window. One is to duplicate the sequence in the project window, and export the duplicate. Another is to create a new blank sequence with your desired specs, copy everything from your old sequence and paste it into the new. Another is to duplicate the project in finder/windows explorer and work from the duplicate. CC and CC 2014 also seem to have issues for some people (including myself) when the project file is on an external drive, so if it is, copy it to your desktop and open+export from there.
