iMovie will not export
I have an iMovie I'm trying to export/save. It pops up on my desktop as two separate files... One is a Quicktime file that, if I click on it, it says "Cannot open, file not supported by Quicktime". It saves as another file that is a nondescript file and will not open because there are no apps on my laptop that will open it.
It's a 17 minute video of me reading a book. It has a music file looped underneath my reading. And pictures inserted as I read along in the book.
Everything saved normally before I added the music and pictures.
I tried removing the music and pictures and that did not help. The files were the same as before. They would not open.
So frustrated. Please give advice if you can!
