Not a traditional UFO sighting, probably nothing but it was a large snake shape I'd never seen before

When walking to work I originally saw it going towards and over the buildings on the left of the video, I was walking the opposite direction as someone else so did not take a video until they passed, at which point the object was further away.
It originally was HUGE, with four snake shaped curls going different directions if that makes sense. By the time I shot the video it appeared to just be one snake like object, always black even at first.
The video is not great quality, and at first I get distracted by a bird or something, but you can see the figure in the middle at the start of the video before I focus on it.
