Cannot create optimized media in FCPX for ONE folder
I am trying to create optimized media for all of my files of a documentary. It works, but on one folder/event, I am only able to create proxies, not optimized files. The event contains drone footage froma a dji mini 2 - all other folders with the same filetype and same video settings work fine. I tried to delete all generated media files - no chance. Why is this folder not working?
