2.35 published image in disk?
I've been reading around for a while, but can't seem to find a direct answer to a question of mine. The experts live here, so I'm hoping for some clarification.
It's well known that anamorphic on bluray has at least a common publishing format of printing the cinemascope 2.35 image on the disk, surrounded by top and bottom black bars. The projector can mathematically expand to fill the screen vertically, with the lens expanding horizontally to fill out a full 2.35 screen. However, that still means that the source material of the projected resolution originates from the dimensions of that small (810 out of 1020) published frame. The rest of what comes from the projector lens is mathematic enhancement. Might as well stay with standard DVD at that point, which was, what, 720?
So here's the question. As film did so masterfully in handling anamorphic, does bluray ever publish (in a separate file, of course) the full 2.35 image just squeezed horizontally, and plunked onto the *entire* 1.75 frame to be simply re-expanded by an anamorphic lens? Direct and simple.
I'm aware that the publishing arithmetic would probably not come out completely even, but I wouldn't be surprised if the resulting loss of image on the sides to make up for math slop would be tiny, cut off at printing. Betcha less that a half of one percent. The result would still be microscopic closeness to the original 2.35 at full resolution. Probably only the director him/herself would even know. Full frame usage would mean no published black bars, full 1020 resolution with *virtually no original image loss*, and no artificial vertical stretching necessary. Brightness *may* need additional bulb wattage. Low setting, high setting. Maybe. Doubt it, actually.
I'm told that this is how they did it on DVD. (don't know, to be honest: rumors...)
So what's the answer? Does this exist on bluray? True full full frame anamorphic printed on the disk itself? Thanks.
