And it's not just for "Avatar." In 2008, I made an AMV for The Spectacular Spider-Man. Thus far, that's the only non-Avatar AMV I've made (aside from a really lame one for MAR using the song "Caramelldansen," which I very much doubt I'll ever be uploading to this site). I've had ideas for AMVs for some other shows, too, but not many ideas, and most of them were never that important to me (the ideas, not the shows... shows are important). I have an idea for a PMV** I want to make for My Little Pony: Friendship Is Magic, but I have no idea if I'll ever make it, because I'm not sure if I can get the episodes onto my computer. (I even bought an episode off iTunes specifically for that purpose, but then the program I wanted to use refused to recognize the file format, because iTunes is evil.) Anyway... I don't know that I'll ever have many non-Avatar vids even if I do get back into making AMVs, but we'll see.
Also I need to mention that not all my fanvids are AMVs, though most of them are. There's one promo and one fake trailer I made, both for Avatar. There's also a really weird thing I made for Lost. And um... I don't remember if there's any other fanvids I've made for anything. I really feel like I must have made something... maybe. Or maybe not. But whatever, it's not important. What's important is that years and years ago, YouTube deleted tons of fanvids by lots of users, including me. Then I started using an inferior site called VidiLife, which doesn't even exist anymore. And for a little while, I had an account on a third site... I think it was LiveVideo or something like that. I just had two vids there, the Spider-Man one and the Caramelldansen one. But that site seems to be gone now, too. And now, in 2015, I have decided to just upload my old vids to my own website, instead of relying on other sites to host them. This could eat up my webspace and bandwidth, but at least the site won't disappear, or use tons of ads and junk, and probably no one's going to force me to remove the videos.
*AMV technically stands for Anime music video, which means that many people will not consider any fanvid (songvid) that uses western animation rather than anime to be a true AMV. But personally, I prefer to think of AMVs as "animation music videos," whether they use anime or not.
**PMV: "Pony Music Video" (an AMV using scenes from "My Little Pony: Friendship Is Magic")
