Video Intro has many types of options. It can be made on PC, Mobile, and Laptop. For PC and Laptop but Laptop can be laggy (it depends on your Laptop), there is a lot of options which is After Effects, Panzoid (Website), Sony Vegas Pro, Blender, and more software or websites. I do not know about mobile but I'm pretty sure there is a software or website that can be used to make Intros.
