Either you're in the filmmaking mindset, or you're not. It goes back and forth, for me. If we have a shoot coming up, usually around two weeks prior to crunch time I will suddenly flip into the filmmaking mindset. The more time you spend among film people and the deeper you get into the filmmaking circuit the easier it comes to you, and there is a sure-fire way to tell if you are in the mindset or not. You start to think in this language:

If you feel like you know what some of these words might mean, be advised (and beware) that the video world steals words and makes them mean something else entirely. And, these are only the words I've actually heard used and sort of understand what they mean. There are many more.
