Scrolling in Unity?

When I scroll in (to get closer to an object) I get to a certain point where when I zoom in I just go way too far in and it’s gone past the object. It’s a cube with scale 1 on everything and is set at 0,0,0. On the video I’m watching:

The guy doing it can zoom in nicely and it doesn’t go too far in. Any idea why mine does this? Is he holding a key?

Any help will be greatly appreciated.

Try pressing “F” to focus on the object (the mouse pointer should be in the scene view).
