Still happy with my 4,1->5,1 W3680 internally expandable computer my only updates this year are software-related. I just updated to FCPX 10.1. I had no trouble introducing the Library-structure over my existing Events and Projects. I then tried exporting a movie I cut and exported yesterday. As I recall the export time yesterday, it was significantly longer than the export I did today after upgrading to FCP 10.1. In both cases the entire movie was rendered on the timeline before starting the export. Could somebody BEFORE they update to 10.1 try exporting a movie (and time it), then do the FCP 10.1 update and then do a similar export of the same movie and time it again? Would be great to get verification/rejection of my hypothesis, that 10.1 cuts the export time by a significant margin.
