Animations/Effects on UV

So I understand how to get UV maps of your 3D model and then you unwrap the model and that’s where you apply your animations for the projection mapping. I’m not 100% sure exactly how to do it though or the exact steps and how to lay the animation down. Is there a video or tutorial for more on this? I’ve just been taking a photo and laying effects on that. I want more in depth animations and effects. Can someone point me in the right direction?
