I’m Looking for an app for iPhone or ipad that allows me to add a text box that will move over a video. For example: If I have a gif or short video with a skateboarder that moves from right to left across the screen, I’d like to overlay their name and have that text follow the person as they move across the screen. Or if a person jumps the text would jump with them, up and down. Make sense? Anything like that for a mobile platform or only advanced editing software For a MacBook? Thanks in advance.
