I'VE TRIED TO EXPORT MY PROJECT NOW FROM BOTH MY MAC PRO AND MACBOOK PRO, BUT ON BOTH MACHINES I'M GETTING THE MESSAGE 'PREPARING MEDIA FOR SHARING', ON WHICH IT STAYS, IE IT CRASHES EVERY TIME, ON BOTH MACHINES.
Sorry capslock. So it's not hardware. I've tried copying the project to a new library, removing all fx, but it still doesn't like the MXF export. It also won't export Prores any higher than 422.
