Suspicious 'Hologram' UFO Still Manages to Confound

A UFO video on YouTube, which makes some wild claims and seems suspicious, still manages to produce an image many are puzzled by with no explanation. What is it?

The video claims to show "leaked footage" of a holographic rendering of an unidentified flying object zooming through the sky. The footage seems to be passed through a filter and the poster makes the claim it's all part of a "HARP" experiment.
