Star looking ufo in sky starts to move then dim out and get brighter

I came home roughly at 1:00 Am on the 12 of April so the first hour of Easter Sunday.  I get out of my car, (I’m always staring at the sky the stars more specifically I go outside and smoke and just stare and even take picture of some stars) at this time I’m sober and haven’t smoked yet and I notice this very bright star off to the north east and I go around the back of my car pull my stuff out of the trunk to go inside but again once I started walking inside it caught my eye and had my attention again.  it looked unlike the others and was a bit brighter that’s when it started to move north mind you this whole time it had not moved at all and now it starts changing in brightness so I put my stuff down and start recording.  It is very hard to see on camera but you can see it gets brighter and then dim out to nothing but not like a normal light on a airplane that strobes this was actual diming kind of like it was turning invisible and then it looked as if it had a big blue force field around it and started drifting north again until it was out of site I actually put my stuff back in my trunk and got on the i17 going north to try and capture it on camera again moving but had no luck.  I drove around until the 2:30 am it had blown my mind my life stents have recorded something similar years ago coming home from the casino late at night.
