Maybe a “tilt and scan” 16:9 version? I get that the aspect ratio it’s presented in is part of Snyder’s vision, but the ratio makes no sense for home video consumption (which is at the moment the only way you can see this film). Hell even Christopher Nolan, who actually films on 70mm IMAX and has a reason to use that aspect ratio, converts those sequences to 16:9 for home release in order to retain as much of the “IMAX experience” for home viewing as possible.
I agree - not sure on the technicalities, but a better aspect ratio. I never like black bars across tip and bottom, but at the sides is terrible. A lot of his frames don’t need to include as much- there’s space over heads, there’s whole torso. I’d rather fil more of the screen. Converting nearly 4 hours of frames though- never going to be an optimised conversion without a studio input.
