Watain-translation (I'll refer to the reporter as R)
R: So how does it feel?
H: About what?
R: Well that you've won...
H: Was it unexpected?
R: Well, you had strong competition from Sabaton didn't you?
H: No idea...
R: You don't know nervous chuckle (asking E) Did you have competition from Sabaton?
E: (in a rhetorical tone) I don't know, did we?
R: (Turning towards P, asking if there was strong competition from Sabaton)?
P: Uhm, yeah, well... No.
R: No?
P: That's how you see it... But we know what it's about.
R: So how does it feel to win "heavy metal-album of the year"? Does it strengthen you to 2011?
P: In your thing yes, but we know what we do.
R: And that's the way it is...
R: (asking H) So how does 2011 look for you?
H: Pretty much like 2010.
R: You're gonna win a "Grammis" this year too?
H: No.
R: No?
H: We're not gonna write a new album until then...
R: (asking E) What does winning a "Grammis" mean for you?
E: Like Pelle said (flashback to P's statement about "we know what we do"), probably a lot in media, but to us it's kind of weird. We have to put ourselves in some kind of (H interrupts and says) middlepoint.
R: (addressing H) Will there be a party tonight?
(H shrugs his shoulders)
R: You don't know?
H: No.
R: You're already partying, good.
(H is poking the reporter and his camera man with flowers)
R: We're doing a flower war here. Big congratulations guys.
R: (to H) Don't forget to bring the flowers home.
H: I won't.
R: Thank you. Congratulations you guys!
H: Häpåre! (which Swedish viewers will recognize as a line from Sällskapsresan)
Then P slaps H with flowers, H gets mad and calls P an idiot, and that's the end of the video basically.
