Convert 3 Hour Movie DVD to KDVD?

khusru · #1 03-03-2004, 09:30 AM

my family normally gets a lot of indian dvds, these are original disks, single layed (4.7g), and normaly anything up to 190 minutes on a disk with dolby digital 5.1. now i was wondering how they do this? you can fit 2 hours in a standard disk at best quality, so are they using a kdvd template or something similar? the quality is what ud expect from a original dvd ...excellent.
any ideas anyone, just a bit curious

120 min on a 4.7GB disc gives 4500 Kbit/s as average bitrate.
180 min gives 3300 Kbit/s (I took an audio at 128 Kbit/s)

A lot of movies won't suffer to be "limited' to 3300 Kbit/s because they are easy to compress. That's perhaps the case of these indians movies.

90% of all avaiable original manufactred DVDs are based on a DVD-9 and not DVD-5 size format!, meams that DVD-9 gots up to ca. 8-9 GB which is needed for a good orig-mastering of a movie which contains 190min and maybe multiple audio 5.1 added.

DVD-5 therefore 4.7GB is a consumer format we do use for our backups.

So your indian sources IMHO are just copies

Don't forget that India's movie industry produces more films each year than Hollywood (near 800 !). I greatly possible that the local DVD production is done on DVD-5 and not DVD-9 beacause they are easier and cheaper to produce (official copyrighted DVD can actually be done a dvd-r burn on a PC

)

I know (also best movie billboard painters do come from there!)

But according to your last statement: You could be right

thanks guys, all the original disks i got are from genuine retailers like hmv and the disks are 4.7gb as iv checked on my computer, so i think ur probably right about them being DVD-5, i got a stack that are from asia and they are also 4.7gb ( single movies as well as two in ones)
