I haven't seen a thread for fanime convention videos so I decided to create one. If you recorded the fanime event please reply with your video below. I will love to see it and I'm sure others would love to see it too :).
My video is 16 minutes long and the groups that stand out the most is
League of legends (I got garen to do his skill "judgement" spin to win!).
Vocaloid and the part of the vocaloid gathering,
Naruto (I got most of them dancing in a huge group :D),
Gintama (I got gintoki to pick his nose)
Black Rock shooter (Got black gold saw, strength, dead master, Black rock shooter, and white rock shooter in the video)
Ruroni Kenshin (I got a live action movie scene collaborated with shishio, samurai x kenshin, and sanosuke)
Here is the video
