The Black Vault TV

Description found for video: I found this on a stumble page. I have seen it on youtube and cant find the page so here it is. Someone in mexico recorded this. I have seen a lot of alien videos but this is one of the most strange ones. The first alien looks weird but then the second alien comes into view and it definitely does not look like a man in a suite. They also move funny and fast and the people with camera are really freaking the hell out. Some one explain this video?
