Hi folks -- I'm relatively new still with DSLR video shooting (coming from film). I've noticed that movies shot digitally can sometimes have areas in the image that seem "dead" in spots, usually colorfields, like a blue skylook, in which that area of the image looks more like a computer that's seized up and stopped playing than simply part of an otherwise "moving image".
I've seen this in films shot on low-end DSLRs, but also on big budget films, where I assume they are using state of the art cameras.
Anecdotally, I've seen it more on black and white films than color, and I've seen it both in the theater and on small screens.
I'm assuming that this is an element of how the microprocessors save space: if something isn't moving in a way it detects (like a sky) the processor will not refresh the image for as long as it can to save processing speed/space. Or something to that effect.
Also it's usually in well lit shots, so I'm guessing the absence of video "grain" contributes to the problem.
But... does this ring any bells, and is there something one can DO about this phenomenon? I've seen it in some of my work, (Panasonic G7) and I hate it. It seems to me that adding some kind of grain plugin is crummy solution, but maybe I need to get used to that idea.
Thanks for your time!
