Very slow cyclic rotation animation in a few seconds

I want to create a very slow cyclic 360 degree rotation. The thing is, the whole animation film is just a few seconds, which is not enough for a full 360 degree rotation. Am I missing something? Is there another way to do this?

This is the tutorial I used


If I’m understanding you correctly, all you need to do is extend the duration of your render, which you can do in the render properties panel (the “End” number – make it higher!)
