January 31 2012—convincing UFO video?

I was looking at UFO casebook today and I found this interesting video from Costa Rica.

I get a good feeling from the witnesses—I don't think they're lying. I really don't know though.
One interesting aspect of this video is that according to the witnesses the UFO was very small. Not nearly large enough to house a regular sized human. It is suggested this is some kind of alien probe.

I think the video looks authentic, but really I have no idea.
What do you guys think?

flying saucers are without a doubt real. i've seen two of them in my life. whose driving them is the real question.
