It's been a while but I have used Movie Maker 10 (or at least that's what it was then) and it was very good for being free but the tutorials available (although minimal) do lead me to think that this has a far greater scope for creating a pro video?
It's received a few best in tests and I've a few weeks left to play about with it before I decide.
That said I could put the money towards a Minn Kota engine for Jims' Christmas.....
