well the sony vegas i use is pro, there are sony vegas movie studio, vegas movie studio platinum and pro.http://www.sonycreativesoftware.com/products/vegasfamily.aspthey are expensive, especially pro because pro they use to make real movies that go in theatres.You can download demo and use it for a month, but then what i did is got a keygen and got it for free :)I gota start learning somewhere.Also after effects took me a loong time to find the real download.I might give you the keygen if you want.
I use Womble. Womble is fun.
