Looked up & saw a large pulsing ball of light. Took video & enlarged it 2x’s & noticed it’s actually a rectangle of light

I was watching television with my fiancé when I felt like I needed to go outside for some air. When I sat on my front steps I looked into the sky and noticed what looked like an extremely large flashing star. It was so strange that I pulled out my cellphone and began to record it.
Afterwards I expanded the video and looked closer and I noticed smaller lights surrounding the original light. My search to find out what these tiny twinkles were lead me to look at my video frame by frame where I then got an extremely clear picture of what looks like a perfect rectangle of either light or smoke. The object remained in the same place for the next two hours at least before I went to bed. I will include the original video, my zoomed in video of the object, and my final still shot of the rectangle showing which part of the video I got the stillshot.
