AMV competitions in this time age can either go very right or very wrong depending on the quality of the entries it receives, or at least that's how it is in my book since the large competitions out there have become dull with almost no notable entries.
Regarding the project, I myself am just an editor and have 0 marketing/advertising experience so I cant help with that aspect, but I know from experience that a badass promo video has never failed to motivate editors before.
I am "interested" in this project, but sadly I wont be free enough to be depended on as I'm starting with uni soon, but then again I'm not sure what exactly would be there to work on.
