Hi halmi,

To avoid that you need to set the rotation pivot point as described above.

When you want to orbit around a particular object, select it and push the "Reset" button.

If you want to work closely on a small area of an object either select an edge or face in that area and push Reset or use the Area zoom button to snap on to a specific point.

In your video the problem is that you're not using either one of those methods.
