What source to use for 2.35:1 movies?
I was investigating CIH as I’d like to purchase a CinemaScope size screen. What I read is ‘you need to use an anamorphic lens because you’re loosing x% of the projector’s 4K capability to black bars’.
However, Blu-Ray isn’t an anamorphic format so with a 2.35:1 4K Blu-Ray movie that loss has already occurred at the source level, so the anamorphic projector output would be an upscaled version.
Are there other sources where the source truly uses the 4K pixels available for the full 2.35:1 movie?
