The 3d is excellent on this title to my eyes.
Having said that, I think I know what you guys are describing and seeing as I have noticed this on some of the Netflix 3d streaming like Art of Flight. I wonder if this is something that can vary from person to person as far as how we process 3d on certain titles? Not sure, but I brought up what I was seeing in some scenes with AoF in another thread and the posters that responded did not see the same issue. Who knows!
There is definitely an error and it seems some are more sensitive to it than others -- it starts at about 11:00 min into the film.
Here's a description of the problem:
"The reason that scene is causing eye strain or headaches is because in addition to the necessary horizontal disparity that makes stereoscopic 3D work, there's actually some accidental vertical disparity because the left eye image seems to have a slightly different aspect ratio. Pause the image and look at the top of the screen with each eye in turn and you will see that there is detail present in the right eye that's not present in the left eye. For instance, the frame I paused on showed a pilot's torso and in the right eye I could just see the bottom of his pec at the very top of the frame, but in the left eye the bottom of his pec wasn't visible and would've been just outside the top of the frame."
I'll try checking those scenes specifically when I get the chance to see if it was something I missed or if there's a possibility that there are defective copies or maybe decoding errors.
To report back on this issue, I followed the directions in the description and can absolutely confirm its veracity on my copy. In that section, there is a height mismatch between the left and right eye frames somewhere on the order of 5-8%.
Apparently, unless I'm specifically looking for it, I'm not particularly sensitive to it, but I can confirm that it's on my copy but went unnoticed till I read the description and specifically looked for it frame by frame.
It seems my eyes have no problem auto focusing at different heights to create the 3D image. I didn't even realise that I did this till I was using my hand to rapidly cover first one eye, then the other, back and forth while comparing the left and right eye images. As I did that, I noticed that the top of the screen image was jumping up and down as I went from one eye to the other. Each eye was auto centered on its respective image to provide a coherent, properly merged picture. Since I tend to focus mostly on the center of the screen, I didn't notice the 5-8% discrepancy at the top and bottom of the image.
Just out of sheer curiosity, I wonder if this natural tendency has any connection to lengthy amounts of time spent staring at those 3D stereoscopic posters that were popular a couple of decades ago. I spent so much time staring at those that I could find the 3D image in 5 seconds or less, even with my head tilted. I think it might have trained my eyes to focus where they needed to to form a coherent 3D image.
