iMovie Export Problem Error 10004

Hi,

Take a look at the suggestions in this thread and see if any of them help you:

imovie not exporting video to file (error 10004)

-- Rich

So after hours and hours this was my fix, after reading many of posts and combing the answers into one solid fix.

Export to File (save on desktop) When error occurs and stops the process, open the "unfinished" file on your desktop with VLC Player and play the file to the end. Where the project stops in the VLC player, this is where your problem is located in your project.

Mine was imported Powerpoint creations that had black frames in the beginning. Went back to project, found the black frames at the beginning of the Powerpoint clips using the scroll function. Once located, select clip so it is highlighted with yellow square around it, then place your pointer at the beginning of the clip (where the black is) and press the "R" Key on your keyboard while clicking down on your mouse and (this is the Range Selector Box that will pop up with a small yellow box) > Adjust your Range Selector Box to the beginning of the clip where the black is, (the default on mine for "time" in the range section box was 0.6 seconds) then, either right click & delete, or press delete on your keyboard, or edit-delete. I had to do this for 6 out of the 8 Powerpoint creations that I had imported.

Export you project again and hopefully it works, as mine did.

Thank you to all for continuing your support.

I also removed all audio (detached audio and deleted) from my Slow Motion clips, this may have helped, but the real culprit was the black frames from Powerpoint.
