Sorry! Sorry! I figured that the staff would've emailed the participants.
Well, this is only from memory, but the contest showed some runner-ups at the beginning and concluded with the winners.
xXtokiovampireXx "Before the Storm" using HOTD
l33tmeatwad's "Anten Piece" using Outlaw Star
Alchemymini "Hour Glass" using Tengen Toppa Gurren Lagann
(a few local entries, none of their names were recognizable to me, but included a Hellsing AMV)
A promotional dance AMV (don't remember the author's name but it was for a con from 2012)
...there were more but you'll have to contact the staff about it, same email for the contest.
Magicflier's "Turning the Tables" AMV using Saki
Dreww's "Chance" AMV using multiple anime
Galia & Kitty's "Saudade"
Striking where it doesn't hurt.
