| whatever said: Even if you have a 1080p TV, it doesn't matter for movies at all. 1080i and 1080p input to a 1080p TV for movies will look identical. This is due to the fact that movies are filmed at 24fps and the 1080p displays accept 1080i/1080p at 60fps. I had a quote somewhere. Found it. Below is Evan Powell's (Projector Central) appraisal of the 1080i vs 1080p controversy. "The truth is this: The Toshiba HD-DVD player outputs 1080i, and the Samsung Blu-ray player outputs both 1080i and 1080p. What they fail to mention is that it makes absolutely no difference which transmission format you use—feeding 1080i or 1080p into your projector or HDTV will give you the exact same picture. Why? Both disc formats encode film material in progressive scan 1080p at 24 frames per second. It does not matter whether you output this data in 1080i or 1080p since all 1080 lines of information on the disc are fed into your video display either way. The only difference is the order in which they are transmitted. If they are fed in progressive order (1080p), the video display will process them in that order. If they are fed in interlaced format (1080i), the video display simply reassembles them into their original progressive scan order. Either way all 1080 lines per frame that are on the disc make it into the projector or TV. The fact is, if you happen to have the Samsung Blu-ray player and a video display that takes both 1080i and 1080p, you can switch the player back and forth between 1080i and 1080p output and see absolutely no difference in the picture. So this notion that the Blu-ray player is worth more money due to 1080p output is nonsense." |
sorry, that is not correct for displays. progressive scan means the tv refreshes the image one line after the other, progressively, every 60th of a second. interlaced means the tv refreshes 540 lines in a 60th of a second , then the other 540 lines in another 60th of a second, the entire process taking one 30th of a second. that means it takes twice as long for the entire screen to be refreshed. you should just go to wiki to understand the undeniable physics behind the different technology. there may not be a huge difference but it's still there. a 1080i display is simply UNABLE to "reassemble them into their original progressive scan order." it is not possible. @makingmusic, i don't think you'll see LotR anytime soon, Jackson's being an ass in some legal dispute with new line... hell we'll probably see star wars first.
