The thing is that the whole video's format is "lying down". Which means that the width is longer than the height. So far so good!
But then I want to add some videos that I filmed with my phone. And this video is "standing up". You know, the height is longer than the width.
Everything looks good on the timeline. But after I've rendered it and watched the video it just left black empty spaces where those "standing" phone videos should be!
I have added other phone videos which "lays down" and those works flawlessly!
What should I do to make my "standing" videos work? I've search for answers everywhere and tried everything! :(
