The video you see above, while incredible, is not official. But, made by one Billy Hanshaw of Leeds, it became such a viral sensation that eventually Who showrunner Stephen Moffat saw it, and he's using it as the basis of the actual season 8 opening credits! (With Hanshaw's permission, of course.)
Seriously, that's how good these fan-made credits are — they've essentially become the real thing. Sure, Moffat showed the video to the BBC graphics department and told them to make an "official" version of them, but that's more a matter of the BBC's presumably superior resources; Hanshaw's video could easily be the real credits just as it is.
"It was the only new title idea I'd seen since 1963," said Moffat at a Who press conference. "We got in touch with him, and said, okay, we're going to do that one." Nice! You'll be able to see the "official" version when Doctor Who season 8 premieres on August 23rd.
