Final Cut Pro X 10.1 and later: Unable to render or share a project

Sometimes you might not be able to render or share a Final Cut Pro X project. This can happen if you copy a Final Cut Pro X library to iCloud Drive, or transfer a library using a third-party file sharing service.

Files stored in iCloud Drive are uploaded to iCloud so that you can access them from all of your devices. However, Final Cut Pro X libraries should not be stored on iCloud Drive or other cloud-based sharing services (like Dropbox) without compressing (zipping) the library first. The fastest way to move Final Cut Pro X libraries between Macs is with an external hard drive.

You can move a Final Cut Pro X library to a cloud-based folder using these steps:

  1. Locate your Final Cut Pro X library in the Finder.
  2. Right-click or control-click on the library icon, then select Compress from the shortcut menu that appears.
  3. Move the compressed version of your library to your cloud based service.

To use the library, move it from the iCloud Drive folder (or other cloud-based folder) to a local drive on the Mac where you want to work with this library. Then double-click the local copy of the compressed library to decompress it.

If you've moved a Final Cut Pro X library to a cloud-based drive without copying it to a local drive or compressing it before uploading, you may not be able to open the library. You can use these steps to address this issue.

  1. Open the Final Cut Pro X library containing the affected project.
  2. Create a new library by choosing File > New > Library and save the Library onto a local drive or SAN. Alternatively, open an existing library that isn’t stored on a cloud-based drive.
  3. In the Final Cut Pro X Browser, drag the cloud-based event/s into the new library you created or opened in step 2.

If your media is external (stored outside the Library), then it remains in its external location. If you manage your media inside the library, it may appear that your media has been duplicated. 

Final Cut Pro X creates links between the media in the new library, and the media files in the affected library you copied the event from. If you delete the library that contains the affected project, the media files remain in the new Final Cut Pro X library. If you delete the new Final Cut Pro X library, the media files remain in the affected project and event. By using links for media in this way, Final Cut Pro X doesn't have to copy media files or use additional disk space.
