Shape shifting chrome spheres

I noticed what I thought might be an airplane in the distance with the sun reflecting off of it. As I observed more closely I noticed that it was moving unusually. The object came closer to my location so that I could see better and realized quickly that it was not an airplane but a sphere that became two and then three. It was hard to determine if the object was reflecting light or emitting light. The object was moving north to south and then back north again and was shifting from one object to two and three while spinning around one another. I then observed another object just to the north and at the same altitude as the first one. I witnessed both objects at the same time moving and changing shape. It looked as if there was stuff falling or being dropped from beneath the objects. One object appeared to descend somewhere to the southwest, as I lost sight of it behind the roof of my house. I watched the other object for close to an hour while it sat fixed in one location in the sky, but seemed to be getting higher in altitude. It looked as if it was disappearing and reappearing. I could only faintly see what could be described as the light reflecting from it or light it was emitting. It finally became too small for me to observe any more. I have video of what I saw but it does little justice to how I witnessed this with the naked eye. Sorry for the shakiness of the video. It was difficult to have a steady hand while zoomed in.
