Filmed a craft that disappeared and reappeared

I saw a singular unidentified flying object hovering far up in the sky. It’s suddenly faded away as if it disappeared. I kept trying to look around to find it, and when I looked up and saw an airplane with a vapor trail I noticed that the object had reappeared and was following the airplane. There is a second object in the lower left area of the screen that can be seen fading away near the end of the clip. The short eight second video shows me filming the plane again briefly after and the object completely disappeared by then.
