Here is a much better version of it, much more clear.

I´ve seen this video some time ago. It´s CGI for me. In the initial sequence, when the "object" aproacches, it kinds of "zoom in" (it´s like an "artificial" aproachment, note that the image of the object aproaching doesnt change...doesnt rotate, doesnt change lighting...just like it "zooms".

Sorry for my english.
