Constant direction and speed? Check
It looks like a balloon.
Would be nice to see original non-youtubed video though, because it looks like it's been filmed with a decent camera
Bring on the flamers coz I called it a balloon


I disagree, it looks more to me like a giant full stop or maybe the dot from an exclamation mark.
It probably escaped from the end of a sentence on a billboard or something.

Science dear boy, if it was helium then it would be rising constantly. It moves in a linear sideways direction with almost stable velocity, that doesnt fit with wind. It then rises upwards with very little sidewards movement, again at a pretty constant velocity, that doesnt fit with wind.
Whatever it is would appear to be something controlled more than blown, a remote control something or, well, I guess something else, could be some kind of kite although I dont see any strings and the movements are a little odd for a kite, however kites are very popualr here in aregtnina and they come in ALL shapes and ALL sizes, some of them are pretty impressive things really.
