How to properly create animations…

Godot Version

4.5.1

Question

I’m just starting with Godot, and with game development in general, and I’d like to create my own sprites.
So I’m wondering what the best approach is: should I create a new image for each animation frame every time, or, like in RPG Maker, use a single sprite sheet that contains everything?
Is there a recommended format or best practices for this?

Both work with Godot. Using sprite sheets is easier on import, but there are also free online tools for turning individual sprites into sprite sheets.
