Hey! I think I got in late and I got in when I was 17. I got beat at a film festival by a guy who made his first movie at age 8. I'm getting into graphics/VFX/motion graphics now and know the tiniest bit of everything.
Getting started...now there's a question. Do you want a job, or do you just want to learn and make stuff? There is a very big difference to me. I recently graduated with a 4.0 in Video/TV production from my local community college and can't get a job for beans. Most of my 5 short films have flopped badly. I keep at it and I'm now working on my first music video(it should be a big hit, I hope, but then all my movies were supposed to be hits)
I would say(like Robert Rodriguez, the Hollywood director), skip film school and get out and make movies. Rodriguez says in his book that everyone has a couple bad movies in them and it's better to get them out as soon as possible. That's true in my case.
I would recommend reading Rodriguez's 10 minute film school(google it or buy his book, "Rebel Without A Crew"). It will give you a good start.
If you would like to learn software(good idea) then learn one of everything: video editor, audio editor, 3d animation, motion graphics, DVD burner. Pick one company and learn all the software it has, like Adobe's Suites or Apple's Final Cut Studio or Sony Creative Software bundles. It will help getting a job later, if you want one. Get the free trials off the company's website and fiddle around, watch tutorial videos, etc.
Tutorial Video sites to check out:
lynda.com (awesome. teaches almost every media software known to man, but you eventually have to pay)
Adobe TV - tv.adobe.com(if you learn adobe stuff, you gotta go here!)
I'd also recommend reading Videomaker magazine and "The Art of Video Production" by Leonard Shyles.
Hope this helps. This is a favorite topic of mine as you can tell. Thanks for asking so I can answer!
