The wind and air-currents buffet the balloons about giving the impression of altering shapes and configurations and the slightly deflated balloons are also prone to altering their individual shape. This movement also means that the sun is reflected from different points on the balloons as they shift position and shape. No mystery. No UFO. An IFO!

that doesn't explain the that similar looking ufo flying in that youtube video i found.

It wasn't that similar. From what little detail could be made out in that video, I'd surmise it was a bunch of 'round' helium-filled foil balloons.
