iMovie cannot create file
Hi
I could always create a file from a iMovie project, but now it does not work anymore. I am getting the message "Exporting My Movie has failed", then: "The operation couldn’t be completed. (com.apple.Compressor.CompressorKit.ErrorDomain error -1.)".
I have tried everything, spending hours, including changing the compression settings. I do not know if this is a coincidence, I just updated Sierra.
Any help would be very much appreciated!
