That’s because these scenes were shot with anamorphic lenses which gives a native 2.35:1 ratio. For such scenes, just include the 2D Blu-ray cinemascope counterpart. No need to use a cropped shot.
But then it wouldn’t be an as close to accurate representation of the IMAX version, which is what i am aiming for. From what i can remember, it didn’t shift ratios throughout that sequence. I could be wrong, but for this reconstruction i will keep the zoomed shots. It’s impossible to know for sure using the Starz version because the rest of the film is crooped and zoomed. Those would be easy to revert back if we find proof that they did shift ratios anyway
