>Does anyone know who much data 1 hr. of HDTV produces? Let's try 720 for now and perhaps 1080. I'm looking for the file size if you store the whole thing in a single file.
>Well, I didn't have any idea ten seconds ago, but now I know that one hour should be roughly 3 GB. (So a movie should be 5-6 GB.) >hmm, that's normal DVD, isn't it? the newfangled flavors (BD, etc) seem to be 5-10 higher capacity. >compressed data rates appear to be 20-50 Mbps (lower than 20 probably doesn't count as HD.) >funny how all the HD stuff seems very fuzzy ;) 3GB for 1 hour seems reasonable, a movie in avi is only 700MB, and that's at PAL quality or higher. a DVD is roughly 5GB for augments sake, and that includes the .vob video files, audio files and any extras (which tend to be at a lower quality anyway.) so the size of the movie is say closer to 3.5/4GB than 5GB. the 'dvd' movie is not at PAL res, but something like 4 times the quality of PAL (3/4 way there to the lower end HD). the mid and high HD, i wld expect to take between 5-7GB for an hour. thus just fitting a 'HD film' on a dual layer DVD. blu-ray being the choice medium for 'HD films' in the near future. there is also quite a bit of confusion over what "HD" means. often frame rates, and colour depth are different on different 'HD' objects. so it's quite easy to fit many hours of HD film on a DVD at 5 fps. bit off topic... it's funny how VGA is directly* compatible with SCART, also how DVI is directly compatable with HDMI... interesting how in both cases the computer connector came first and yields better quality. just a case of changing connector's (shape and pin layout). *directly meaning no or little analogue electronics used. personally... HD is a marketing CON to get nieve people to buy 'HD' products when they would be better buying a computer monitor with a higher resolution, colour depth, and refresh rate. although a 42" 'HD' widescreen would look good on my comp. -- matt _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
