iMovie failed to export
Hello. I've been exporting files/movies just fine until I made a few edits to an existing project and it's, suddenly, failing to export. I've seen the other posts on this matter but I couldn't find any posts regarding the dialog box error message details when clicked. This is what's coming up: Error: RequestFrameAt returned: 3 for absolute frame: 12442.
iMovie isn't crashing or freezing. I tried restarting the program and then tried restarting my computer but I'm still getting the same dialog box error. Does anyone know what those numbers are referring to? Such as, is that 12442 referring to the 12 minute/44.2 second mark maybe? And, that RequestFrameAt returned --I couldn't find any information on that either upon my first search.
iMovie 10.1.15
OS 10.15.6
Plenty of hard drive space
Thanks
