ok so i started watching the workprint and recording all the parts with dancing greys due to brightening but once i got to the death star meeting room with all the generals i stopped because it pretty much became continuous since that scene is very dark in nature. on the contrary on really bright scenes the dancing greys are not there. here are most of the scenes before the death star meeting room with dancing greys.
5:11-5:13
6:19-6:22 <---when c3po says "hey you're not permited in there its restricted"
6:28-6:29 <---when c3po says "you overweight glob of grease"
6:31-6:33 <---right before c3po says "secret mission, what plans?"
6:39-6:40 <---right before c3po says "i'm goin to regret this"
6:45-6:48 <---when the pod is shot out i noticed greys around it..intentional?
6:49-6:54 <---"hold your fire there's no life forms it must have short circuited" mostly on the back of the guy on the left
12:35-12:42 <---alot of dvnr smearing on the jawas as they take r2 to the sand crawler in the background
12:55-13:49 <--alot of dancing greys especially in the vaccume tube as it comes down to suck up r2
14:23-14:32 <---de'se'd shot of sand crawler
14:51-15:01 <---taps r2, "wake up"
that's as far as i got. they really look like compression artifacts brought out by brightening. I don't think it's my media player because i played the workprint in media player classic, vlc, and windows media player and still noticed them.
does anyone else notice these? It might be my monitor settings.
I guess you could make the case that it is extra detail uncovered from the crushed blacks but they look unnatural. when i'm in a dark room i don't notice grey pixels dancing around.
i don't want to seem like i'm trying to tell you how to do your job though...because you are obviously very good at it :-)
