I made a promo video very similar to this a few weeks ago. On a basic level the steps went like this:
1. Create a flat background plane.
2. Arrange all the resources, images, objects etc on the plane.
3. Put the camera over it and keyframe the movement of the camera to match whatever timing you need. Set the interpolation on the keyframes to “continuous”, “ease in” or “ease out” for a nice smooth animation.
That’s pretty much it!
