I worked for a few years in commercial video production and always got excited when I would look at the video editing timeline and see all kinds of craziness happening. I love seeing a giant multi-track mess because that means that there is a lot going on, and if done well, the viewer won’t necessarily realize that there are so many layers.
But if I was given a project after it had already been edited by someone, sometimes trying to understand what was going on in that timeline was like solving a crossword puzzle and a sudoku puzzle at the same time, all while trying to read minds.
I could even freak myself out if I came back into a project that I hadn’t touched in a few weeks or months and had to get reacquainted. Sometimes a project simply isn’t very kind, and it takes some serious brain power to get a handle on it.
