That’s what I thought.
I’m guessing we’re seeing more vertical info in the 1.78:1 hdtv version because the blu-ray was probably cropped on all four sides (in order to keep the aspect ratio at 2.40:1 without resizing/scaling the pixels down to 3840:1600 / 1920:800 from 4096:1706 / 2048:853) whereas the hdtv version simply crops off the sides to get the picture from 4096:1706 / 2048:853 to 3036:1706 / 1518:853. Hence we’re getting the full vertical information in the 1.78:1 version.
Has anyone done a similar comparison between the blu-ray and hdtv versions of TFA aside from the imax scene?
