Yeah, I used my mouse. I found it difficult using my hand because it was at first too shaky or my hand would veer off :P After a while I found an OK method.

Used the stabilizer provided by YouTube. It made an obvious difference, but perhaps there are ways to go without it.

I'll perhaps look at finding free editing software, instead of using Windows Live Movie Maker, because there aren't as many variables included with it as I would like.
