Rolling Strobe Lights Over Austin, Texas

My window faces west and looks out over protected canyon area. I can see from my bedroom window and saw what I thought was plane, but it didn’t have a defined light pattern or movement pattern. I took video and a few pics of it, then forgot all about it till I saw on my phone today. When I zoomed in on video I was very surprised! Same with pics, the shape is nothing I can identify, round but with divisions in it. I watched it move around for about 5 minutes before getting my phone to take video. I actually don’t remember stopping my watching so I can’t say where it went.
