Movement keeps the viewers visually engages. It allows for stimulation of the brain and keeps a person occupied, in the way of attention. When there are moving subjects it creates an interest for a viewer, which is like anticipation for what is next to come. I have witnessed this when I have showed friends my YouTube videos. If there is just a tree visual they will not look at the screen, and only listen. If there is movement and action going on, they take more interest in the screen, and seem more involved with their attention focusing on the screen.
This also reminds me of older movies, where they are slower, but the movement pulls me in, as opposed to the more modern movies and shows where it is so quick from one scene to another that it can actually make you (or just me)
feel dizzy, almost. I tend to wonder why they have made it so quick. Our brains seem to be constantly in need of stimulation because of the way movies, shows, social media and all of that have trained our brains to be in constant need of short and quick stimulation. I often contemplate on how healthy it is for our cognitive health.
In short, I believe that motion bring the viewers awareness in and keeps it locked in, for the most part, keeping the attention and interest focused on what is moving. It is like a visual treat, and once you see the action, you are intrigued and want to see what will be coming next. Stillness is not going to bring in as much attention, so it makes sense that motion pictures have become so popular. Keeping us all locked in to the screen, always awaiting what is to come.
