I've studied alot over the last 3 years to prep for shooting this feature I'm doing. I've got a couple of shorts under my belt (one I wish I could show you, but it's tongue-in-cheek critical of a company by name, so I can't). practice and reading books about editing will get you where i am...3-4 years ago, anything other than a cut and a cross fade were alien. Now they are the building blocks of much more complex things. In reading, you also find out why a particular cut is made, not just how. Tons of info on the internet...tips and tricks kinds of stuff.
