Object floatimg and strobing brightness, after time it moves changes color etc. Not normal, not helicopter or plane or drone

I went outside of my job and sat on the stairs of 509 south 9th street and looked towards the left and the abandoned school.. Some distance above it was a rather large bright white light that was pulsating its brightness, after about a minute of hovering and strobing brightness it seemed to get so bright it almost looked like it split into 2. If you slow the video down you can see clear space between 2 different color orbs. The object then start moving in a straight line left. Its color was more of a red oramge now, still pulsing. Not like a plane flashing its lights, not a helicoper(because our hospital has a helipad and helicopter) and its movement an and height in sky didn't look like a drone, or anything I've ever seen(and I observe the night sky every chamce I get, im learning the cosmos). It moved in a straight line until disappearing from my view. The weirdest part is that when I'd zoom in to get a better pic on video, it was as f it disapeared, like it didn’t want to be seen. I took still shots of it in slowmo and no clear shape other than an s rotated sideways was shown
