I just had to do this, only I also wanted the keywords added to the file names in the finder. It was a bit of a process that included “Producer’s Best Friend” and “A Better File Renamer”.
1) Export XML of Event
2) Run through “Producer’s Best Friend”
3) Open in Excel (or in my case Google Sheets). Sort by original file name, then copy all FCPX clip names.
4) Paste new FCPX clip names into Text Edit with one name per line.
5) Use “A Better File Renamer” to completely rename the files based on the names on the text file.
I did this to 37 events and 7,500+ clips last week with good success, though it took a while.
