It looks quite real, at some points though. Some other things indicate that the video might of been directed and edited; the slight blur from 0:31 - 0:32 and 0:49 - 0:52 - it looks rather artistly designed, perhaps not on purpose, rather intended for a "distort" kind of look, which would prove the video to be real or more realistic; the sunshine from 0:35 to 0:38 - to me, it looks rather bright and bloomed, quite saturated, which might indicate that the footage was edited; from 0:55 till 1:02 it looks as if the lens flare was faked, since it looks very nicely shaped, has saturated, toned colours and is "animated" without any flinching; again, at 1:03 (between 1:02 and 1:03 to be more specific) and until the video temporarely blacks out, it seems like another approach and trying to distort the video so it would be more realistic, or real.
What makes it real or makes it look real, though, are the following things: the matching of the colours between the ship and the enviourment, though since it's quite dark that could be covered easily; the voices around the area seem to be real aswell and other than that the camera man was quite quiet; the obvious, the ship looks very real - detailed and goes with the movements of the camera.
All in all, it looks real to me most of the time (don't be confused by the quantaty of the content on the "un-realistic part"; those were minior things, which lastes seconds, if not less. The video as whole looks real), yet I cannot help myself but doubt it because of the things I mentioned in the first paragraph.
Although, those 'incosistencies', might of have been the work of the camera itself, but I'm not sure since my knowledge of cameras is, well, ultimately low or pretty much non-existent.
But if it was true the camera-man would be pissing his pants at that moment
