User blog:Akg91794/How do I make one of these movies?

Okay, as you may or may not know, I'm the guy who added the "Barney's Adventures series" page to the "Pooh's Adventures" family, and I've watching a lot of the films posted on here, mostly on YouTube, and judging by how some are video recorded from a video camera, and others are, er, not, I could use some tips on how to make one of these movies. For example:

How do I upload movies that I'm gonna adventure-ize onto Movie Maker?

How should I know which movie I should make first?

What happens after the films I upload onto YouTube or whatever get deleted?

...and stuff like that.

Please comment below with answers and tips, and possible advice.
