Given the information you provided, my best guess is that he assumed you were neglecting getting ready for school to "play around" on your computer. He might also be in a bad mood already, and he may have other instances in mind where maybe he thought you were neglecting responsibilities because you wanted to be on your laptop.
I would ask why he did that, explain that you made sure you got ready for school first, and come to some agreement with him and your mom about what an acceptable morning routine would be and where video editing could fit into it. A lot of conflict is born from miscommunication and assumptions.
I definitely think it was an overreaction on your dad's part and you didn't do anything wrong. But as far as spending your own money on it, I'm sure there are plenty of things he's spent money on for you, though I'm not saying it was right of him to do that. But if he did actually damage it, while in a better mood no reasonable person, especially a parent, would have any problem paying for repairs or replacement.
