Pulsating fireball moving, getting brighter and brighter, goes dim stops and goes again, black hole in the middle, traveling in slow

It began as a fireball pulsating and moving very slowly. Stops and goes dim then proceeds on traveling at moderate speed. Changing direction up and down but still moving forward. Pulsating brighter and brighter.
Bright orange reddish glow with black hole in the middle. Sighting lasted for about almost 2 minutes. It left no trails. Then it slowly just dematerialized and vanished. Unexplained. There was only one big fireball.
I have the video footage with extreme close up zoom in on the fireball.
(In the video you will see a line of street lights that I filmed with the sighting because I needed for my hands to be against a surface while I was filming and I also needed to see the movement of the object.)
