Is it normal that a very simple 7 min video takes 5 hrs to render in iMovie on my MacBook 2016 fully speced. The video in question contains a few imported vids, some pics, a few simple transitions and some background music. Rendering a minute slideshow from Photos is just a short wait, where the animations in ie. Vintage prints, are far more complex. Tested multiple options in the export menus, but the five hour one was "to file", 1080p medium quality. I tried 720p with medium quality, and that was 3 hrs. The lowest option got me down to one hour. Is this right?
