Add custom text to split screen video
I have two videos in iMovie that are playing side by side using the Split Screen option. I would like to add some custom text overlayed on top of the videos. I tried using one of the titles but my text does not show up exactly where I want it. I tried creating a transparent PNG image that contains the text but when I insert the PNG image it does not allow me to insert on top of the video. It basically replaces one of the videos in the split screen. Is it possible to add custom text to a split screen video?
