All too often I see machinima movies that contain weird camera issues that never appear in professional films. They are annoying in a sense, not only because they are blatantly obvious and easy to fix, but because they immediately take me out of the story and tend to lose interest (which is a big oopsie if you are looking for views, and who isn't?)
I've never been able to name them, and describing them often was more of frustrated grunts and groans then anything.
But Kate Fosk over at MachinExpo managed to do both quite nicely, giving great advise with a great sense of humor. Even if you're an experienced director, it's worth checking out:
