[QUOTE]Originally posted by PsyLiam: [QB] "then why are DVD so much better in quality then VCD" CD's were designed to store 74 mintues of 16-bit audio. To fit video onto them, the picture has to be compressed. Like JPEG and GIF are still picture compression format's, MPEG is a video compression format. MPEG-1 was designed to allow 74 minutes of video on a CD, but because of the lack of available space they are fairly heavily compressed. The resolution is half that of VHS, I believe, but because of the lack of ghosting and other analogue effects, the picture seems better (as long as it isn't paused). DVD was designed from the ground up for video. Is uses the MPEG-2 compression format, which is more efficient, and produces a better picture (as an aside, they're up to MPEG-4, which can apparently just about fit a DVD quality movie on a CD. Ho hum). There is a lot more space to play with on a DVD, several gigabytes, as opposed to 740 mb. So they can store more information, which equals better picture and sound. You ever looked at Realplayer files? Noticed that the bigger ones are better quality? (I know that my figures might be a bit off. That's because I made them up). [/QB][/QUOTE]
