UFO - white orb moving at immense speed

Until RUclips finishes processing the video at 1080p, you can't really see much compared to a large flat screen TV.
Caught this UFO orb while looking out the window. It was pure coincidence I happen to catch it on camera travelling at immense speed directly downwards heading to a nearby forest. Is it a weather or atmospheric phenomena or something else?

coincidence no such thing
