iMovie edited recording is cut off when copied
I'm not great at using iMovie but good enough to edit some recordings. However, recently I've edited a recording that appears complete in IMovie, but when I save it to a flash drive, the end is cut off. I've worked on this for 3 days. Re-editing. Is it possible that I'm inadvertently marking the recording so that it ends at that point? Thanks
