Ah man, you make me want to make videos! But, sadly for my own ideas, I reeeally can't get into vidding; aside from the fact I don't have any of the stuff, jumping into that coupled with the writing fanfic...I'd never get any college work done! Bad, bad zoot.
Oh, but the way you describe it...you obviously really do make them. That's so wonderful to read. I mean, you have actual plot ideas, there are themes, story, meaning - you don't just slap a load of nice shots together with a song you like. You create.
I guess that's why they turn out so well! :D
