Straight line of lights in the sky that slowly started going out from right to left

I was driving down the road and looked up and there was a long line of lights underneath a star. It looked like 100 stars in a perfectly straight line and it just sat there. I thought it was maybe a plane or the streak from a plane that had come through or something like that but it was all lights. Then all of a sudden after about a minute it’s slowly starts disappearing from one end to the other. Like all the bulbs were going out or it turned or backed up and was flying away or something. I have video footage.
