Shiny metal flying object hovering low

Spotted a metal object in the sky at a very low altitude. The object was hovering in one spot above the freeway and looked to be a disc shape with a central light. Underneath the object it appeared to be a plane shape but was not moving and just hovered for about 15 seconds in one spot. I captured a video of it and after a few seconds of recording the object blurred itself from my camera. When I looked back at the object after passing underneath it, it had vanished without a sound or trail.
