It seems like many scenes have the same problem. People trying to break it down to a certain formula. I quit reading a quarter of the way through the first post. I actually read Requiett's
*scene specific buzzwords follow
When I was really active in the Drum and Bass (Jungle) scene, as far as composing and DJing, there were always people who criticized my song taste/style because I didn't follow the "formula" that some people thought defined a proper Jungle tune. Also, because I didn't like the ridiculous "clownstep" or the hard-edged "techstep" style that dominated the clubs and chose not to spin that style in my sets, I ultimately did not get much support from promoters. If you are familiar with DJs and what they play, think Dieselboy(techstep), and Andy C or most big name UK jungle DJs(clownstep). The Denver Jungle scene is pretty close minded to anything outside of the techstep and clownstep styles. Many of the DJ friends I had limited their selection of records to those specific styles, only because that is what was expected if they wanted gigs, not necessarily because its what they actually liked. A good friend in the scene finally told me one day, "don't make music for the scene, do what you love and what you feel, and just have fun." I took that advice and just do what I do for fun, and I feel that move really unlocked my ability to be creative in the music I create and mix.
The moral of the story is, I hate when people try to put a formula to something that is creativity based, like AMVs. To me it ultimately closes peoples minds to new and fresh creative concepts. When it becomes too locked down and unaccepting of new things (or things that are too different), I think it can stifle people's creativity. I think any scene that keeps an open mind and is accepting of the cutting edge has greater potential to evolve. I am pretty new to this hobby and am still learning a lot of new things, but I would certainly would be sad if the definition of a good AMV would come down to a formula. Like plenty of people have already said on this board, let's just be creative and have fun doing it.
