Exactly, and I'm extending the comparison a bit by questioning how
editing and style of editing might play into this. The type of visual
content we encounter in the natural world lends itself very well to long
GOP compression schemes. The visual content we create in edited video,
where we might average an edit every 5 seconds (or more) is less
efficient to compress. So if what Khalid told me about how our brains
process visual information is true, highly edited material would put
more stress on the parts of the brain that process vision. My question
then becomes, is this a limiting factor on our ability to perceive a
sense of realism in the type of programming we might expect to watch on
4k or 8k monitors?
I don't know the answer. If I was like my friend Khalid I would drop
what I'm doing, go back to school and do the research. I don't have his
brain or his discipline. --J.B.
