I'm actually a fan of Creative Cloud. I'll gladly pay $20/month to have access to the best editing software in the history of the world. I get every upgrade. And the tutorials? They have a tutorial for everything!
I realize that it's not feasible for everyone to make that monthly payment, and that's not at all what this thread is about. But if you have an online connection, and a decent computer, and can afford the $20/month, that's totally the way to go.
Sorry, Stich, I'm not trying to rub it in your face. But since you brought up CC...
Anyway, I hope you don't mind unsolicited advice, but I think your biggest concern, regarding editing, should be your computer. You can edit on an older computer. It's possible. I've done it.
But the editing process is sooooo much easier on a newer computer, with more RAM, and a large monitor. Splurge on the large monitor, it's worth every penny.
So do what you gotta do now. Don't stop filmmaking just cuz you don't have an optimal computer. But I promise, you'll be glad if you save up some scratch and purchase something better in the coming months.
And yeah, Movie Studio is legit. It's not my favorite, there are some aspects of the editing controls that always weird me out. But it does give you full editorial control, as opposed to most of the other low-end editing software, most of which are dumbed-down for soccer-moms and soccer-dads, so that they can easily put cheesy titles over their kids scoring a goal against the arch-rivals from the other side of town. The dumbing-down of editing software makes it very difficult for a legit filmmaker to do their job, so it's very necessary to get software that has a little bit of a learning curve.
