There's very little that can be said about this video because the figure in the background is just too distant to be able to make any kind of intelligent judgement about it. It could be a hoax. The scene could have been set up very easily, giving a guy in a monkey suit the cue to run across the field after the third shot. (And it needn't even be a good suit since he's so far away.) The most interesting thing about the video is how the "creature" drops down on all fours after its run. Would a hoaxer do this? Maybe. If we are to believe the posters, it could be Sasquatch. The helicopter might be incidental in any case.
