80 percent of successful

80 percent of successful video production is knowing enough talented people so you can assemble a crew when you want to do a project. So, based on my personal experience, what I would do if I were you is go to your local community college and see if they have classes in video production. That way you’ll start meeting the people and making the friends you’ll need when it comes time to do something.
If you want to learn online, sign up for a free trial at Lynda.com, their courses are as good as anyone and you’ll find out if online learning is for you.
The best way to learn is of course to go be a gofer at whatever video companies are in your town.
