change frame size within a video
I am trying to create a tutorial using footage of a screen recording from a mobile device and screen recording from a laptop. The problem I'm having is trying to combine the two. I have the most mobile device footage and that's what I started with so that is the frame size. (looks like the size of a phone screen.) when I try to add in the laptop footage it only shows what fills the smaller frame? I know how to set to frame but I need to do the opposite and have the frame scale to picture.
I've looked everywhere and cannot find a solution. Keep in mind I'm a beginner and self taught. Thanks!
