The "shimmering" on the transporter wall, I wonder if thats the same as other flickering going on. I've noticed it with a few episodes here and there, just in certain sections of the shot. Sometimes on a near closeup of Picard on the bridge, right behind him at the wall behind the tactical station you can see it.
It's almost like a concentration of film grain and definitely has that 24/48hz flicker look to it. I transfer 16mm film at work and notice this some times on older films. I have a sony professional broadcast crt monitor (same one the vfx supervisor has in the behind the scenes featurette) that mimicks it perfectly on the entire screen when it's in 24p/48hz mode. I also noticed it on tube tv's when I was in Australia. (50hz) pal causing it.
I'd rather have it the way it is than some kind of smoothing over or other digital technique to remove it though.
