IMovie erreur. (-2191)

Hi, Oriane,

I do not recognize error code -2191. It doesn't show up in Terminal and I don't see it listed, though it might be on some list that I don't have.

iMovie 11 is not fully functional with High Sierra. That might be the cause of the problem. If that's the case, the solution would be to upgrade to iMovie 10.1.9 (current version). From within iMovie 10 you can update your projects and events from iMovie '11 (version 8).

iMovie 10 has a very different structure and user interface that iMovie 8. So there will be a bit of a learning curve.

Adding to my previous post:

Here are some diagnostics you can try or consider:

1. For iMovie 10, open 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 projects. Now see if you can export.

2. Again for iMovie 10, in your projec do an Edit/Select All, Edit/Copy, and paste your project media into a newly created project and try to share out.

3. Open iMovie in a new user account. The Guest account on your Mac will suffice for this purpose.

4. You might try booting up in Safe Mode (see Help menu) and, after everything has loaded, immediately shut down and reboot in normal mode. See if iMovie works properly.

5. Often export problems occur because of corruption in the project media. Try scrolling slowly through your project, looking for white flashes, black frames, artifacts and other signs of corruption. If you find anything, cut it out of the project and try to export again.

6. Make sure that you have enough space on your boot drive for iMovie to function and enough space on your destination drive to receive the movie. 20GB to 25GB is often recommended.

7. Do a first aid repair, using the Disk Utility app on your Mac. It is found in the Disk Utilities folder located in the Applications folder.

8. Update iMovie and your operating system to current versions. That would be iMovie 10.1.9 and Mojave.

Good luck with this.

The one thing we didn't try is to open iMovie in a newly created library, and then copy your project into the new library and see if it shares out from there. To do that, open iMovie while holding down the Option key and select to create a new library in the box that appears. Then, while leaving the new library open, open your old library, go to the Projects browser screen (that shows each project as an icon), move your cursor over your troublesome project icon to cause a little circle with dots in it to appear next to the title. Click on the circle and select Copy to Library (new). Then see if you can share out from the new library.

Also, you can try making a duplicate of your project to work with (use the same procedure as above, only select Make Duplicate). Then delete half of the project in the duplicate and try to share out. Then delete the remaining half and share out. Keep repreating until you get a successful share. That might help you isolate the problem.

If the above doesn't work, I am out of ideas. You might then consider redoing your project and see if that helps. Keep your old project intact just in case.

Good luck with this.

Glad you found the problem.

Best,
