Unable to share from iMovie - The operation couldn’t be completed. (com.apple.Compressor.CompressorKit.ErrorDomain error -1.)

Hi, Gino,

Adding to what léonie posted you might try the following procedures:

1. Start up in a new user account, such as the Guest account on your computer, and see if iMovie will work properly there.
2. Boot up in Safe Mode (See Help menu for instructions) and, after everything loads, immediately shut down and reboot in normal mode. iMovie won't launch in safe mode, so you needn't try that. You just want to boot in Safe Mode and then immediately shut down and reboot in normal mode.

You might want to take a look at this thread to see if anything in there helps you:

Did you try some of the solutions discussed in thread link below that I previously posted?

As you can see, the Compressor.Kit error is pesky. In addition to the suggestions in the post, try opening iMovie while holding down the Option and Command keys and selecting to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your project.

You might also run a First Aid check from the Disk Utiity app on your Mac, to see if there is a hardware issue. You can also use Apple Diagnostics to check for hardware errors.

Export small project (still of 10 seconds)

What is the file format of your still frame?

have you tried, if you get the same error when using a different still frame with a different file system format?
