A) obviously you've already found this website which is good and I like to visit it everyday (yes it is helpful, but you will realize that theoretical knowledge makes you a better filmmaker in theory) so... B) go out and film and film and film and film and film. If you're anything like I was, you're probably beating yourself up over why the quality of your videos doesn't look Mad Max Fury Road or what you want it to look like in general. The fact that you don't get it right away is probably discouraging and makes you not want to film anything until you know exactly how to get to an acceptable level of quality. You'll scour the internet looking for answers but this is only half the solution. You're going to fail A LOT, but everytime you make something, it's another step. So film something then critique it. Ask yourself what you did better this time than last time and what's still wrong. Go to the internet. Learn about how to do that particular thing better. Film something else. Critique it again. Did you fix that problem? If so, what other problems came up? Did you achieve the look and feel you wanted? Continue on in this fashion. The only way you can do this is if you keep filming stuff and learning from it. Its easy to say "this looks terrible and isn't worth anything" but its NECESSARY to say "hey, I did X thing really well, let's keep doing that". Eventually you'll see improvements (maybe even leaps) in quality as you begin to form a look and feel you actually like and that doesn't make you cringe. Just remember this only comes after hours of footage that does make you cringe. Good luck and always remember to try to see the value of what you do not just the bad stuff!
