This object is a typical cylinder UFO. It does appear to be quite large, which is also typical of this form. There’s no evidence that the object is a computer graphic, but also very little detail about the event, and it’s on a website called the Paranormal Frequency rather than being posted by the individual who shot it.

The website makes this comment: "Filmed by what are called "The Bluffs" in Onalaska, Wisconsin, this huge cigar shaped UFO hovered and rotated for about 30 seconds before fading away rapidly."
