Can iMovie create and export a movie in 9:16 (portrait) orientation?
I have a video that was shot in portrait orientation on the iPhone, 9:16 aspect ratio. I would like to edit it and export it in that aspect ratio. iMovie wants to pillar box it (I think that's the right term) into a 16:9 aspect movie.
Does iMovie support 9:16 movies, or do I have to use a different video editor?
Thanks in advance.
