How do I make a demo video like the one shown on this page: https://premium.wpmudev.org/project/fundraising/
I want to be able to make demo videos of software and plugins and themes and I have no idea where to start. I want to be able to zoom in while the video is rolling and add cool info blurbs and stuff like that. What software do I need for that and how do I get started? Is there a guide?
