Quoting mikl: Quote:
So they haven't used the full resolution on the Casablanca HD discs? Are the black bars on each side encoded into the image? That's not optimal if you ask me.l Why not? What would they gain if they use the full resolution? Okay, Full-HD is 1920x1080 Pixel Case 1: a 1,33:1 movie encoded with pillar boxed black bars. The movie frame is thus 1440x1080 pixels real information with 240x1080 black pillars on either side, and will be shown on a Full-HD-TV with a resolution of 1440x1080 pixel with the additional black pillars. Case 2: a 1,33:1 movie encoded 'anamorphic' The movie frame on the HD-Disk (whether HD DVD or BluRay makes no difference) will be enchanced during the scanning to the full 1920x1080 pixel, but to have the correct Aspect Ratio the player or the TV have to pull it back by digital mumbo-jumbo to 1440x1080 pixel plus the pillars. Same thing as Case 1. What is the benefit? Nothing! And exactly the same goes for 2,35:1 and letterboxing. Again: the anamorphic squeeze was not simply about "quality", it was about "quality if you have to put a 1,78:1 (or smaller) picture on DVD(!) an try to gain a few lines of resolution making use of a specific technical aspect of the cathode ray tube TV" Neither "DVD" or "CRT" are in the picture with HD-TV so anamorphic goes overboard, and rightly so. cya, Mithi |
