Tho while I’m not a fan with cropping the film, if you had too I’d suggest instead cropping it to the IMAX 1.43. I saw the BVS IMAX scenes in that aspect ratio and it’s simply gorgeous. I think an overlay for it should be available in the link I sent to the curious and if not I can happily share mine.
Thanks! This is great. I love having more movie in the fram, but on my home screen it just feels a little wrong. Too much screen bare same with bars at top and bottom of screen.
