I agree it's not evidence, but even then, going by the principle of parsimony (which does not provide evidence, but is a reasonable way of thinking about this) the most likely explanation is also the less extraordinary or convoluted: a guy in a gorilla suit. Why reach for anything else, unless one wants to believe?

The existence of yetis is an extraordinary claim that would require convincing evidence by their proponents, of which this video isn't one (since it's trivial to film a guy in a suit, etc).
