Is it possible for high resolution formats such as Blu-ray and Ultra HD Blu-ray to exhibit video artifacting issues with their transfers?
Let me come at this from another direction...
I've watched my 1080p Blu-ray copy of Captain America: Civil War, since it came out on, first, a Sony 50" SXRD rear projection display as fed by an Oppo BDP-83, and then on my current display, a 65" Samsung NU8000 4K model, as fed by the Oppo, then a Cambridge Audio CXUHD and now a Panasonic DP-UB9000. While I can't recall if the issue I'm about to describe was there when viewing the film on the Sony SXRD, ever since watching the disc on the larger Samsung 4K display, there is a moment that exhibits nasty "shimmering" and weird "twitching/aliasing," and no matter how many people I've asked to test this for me on their setups, the response is always the same: They DON'T see it on THEIR systems.
The scene I'm referring to -- for anyone who has seen the film and Blu-ray -- is in the beginning when the camera is zooming in on the mountainside facility where Bucky is being enhanced as the Winter Soldier, and when we get a closeup of that red "book" with the Soviet star on it (which contains the "transformation code sequence"), it always plays back on my Samsung with nasty shimmering and other artifacting in the texture around the book.
The moment I'm talking about is this one:
That "box" the book sits in starts to jump around with all kinds of artifacts...shimmering, aliasing...it's pretty bad. But it's ONLY for this moment.
Now, here's the weird thing: This happened when playing this 1080p disc in first my Cambridge CXUHD 4K disc player upscaled to 4K, as well as my new Panasonic UB9000, also upscaled to 4K. When I tested the disc in my bedroom, where I have a first-generation Panasonic DMP-BD10A BD player connected to a 40" LG 1080p LCD, I DIDN'T notice the problem (or it was greatly reduced) -- this lead me to believe something in the upscaling of these two disc players was doing something to that scene, for whatever reason.
However, when I asked about this on Blu-ray.com at one point, NO ONE found this issue with the regular Blu-ray of Captain America: Civil War on THEIR displays/systems...and they assured me they were viewing the upscaled 1080p version (to 4K); as such, they insisted it MUST be my Samsung television.
Fast-forward to when I viewed my UHD Blu-ray copy of Terminator: Dark Fate upon its release -- I have noticed at least one moment of artifacting and strange "twitching" in the background of a beginning sequence, when the siblings arrive at their factory job in Mexico. Before they walk in and you hear "Hola!" as they greet the security guard at the entrance, there's a moment when the exterior of the factory is being shown, and I always see that shimmering/twitching in the vertical lines in one part of the factory structure. And this is with a 4K disc being fed to a 4K display...so it's native 2160p to a native 2160p panel, no scaling process taking place.
Is it normal for some discs just to exhibit artifacting like this, even if it's as high a resolution as 2160p? Or is it indeed my television, as many have suggested? Can a display create artifacts on its own even if it's being fed the native resolution of its panel? Would it have something to do with the motion smoothing settings I'm using (Samsung calls this "Auto Motion Plus") that enables smoothing out of 24FPS content but without soap opera effect?
