Im new to all this so excuse me if this is noobish .
My friends dad was stationed in Iraq a little while ago and when he came back he brought some dvds back that he bought from people down there. certain ones have up to four movies on one dvd. the average was about 2 per disc but there were some that had 4. All of the movies had their own menus and scene selections. What did they do to do this?
newer dvd films these days are like dual layer (8gig) of info, most of it being the movie and a little bit for menus / extras...
dont know if your dvds are dual layer or not, if not there (4gig ish) size.
ok, that said putting or getting say 2 movies to fit on 1 dvdr means you have to compress both movies say from 8 gig to to 2 gig, so 16 gig squashed to 4 gig some of that 4 gig being a menu which takes up space too, not leaving alot for 2 films...
now, compressing a film looses quality, the more compressed the worse the picture looks...
ive put 2 films on 1 dvdr useing dvd shrink to compress main movie only for both, then i used TMPGenc dvd authur to make a simple menu. these were older films that came small before compression, i wouldnt like to put 2 newer films on 1 dvdr these days...
thats the basics hope it helps you out...
of course thats going along the lines of the source file/films were dvd format to start with?
the films could of started life as .AVI/xvid format and they may of used an encoder to output at a set size like 1gig hence getting 4 films of 1 gig onto a dvdr, all this will for sure make a loss to quailty, but by the same token be very watchable for most people on small tv's people with 42 plasmas may suffer due to the spread across a big screen though!
Actually that explains allot. now that I think about it I haven't tried to watch his movies on a big sized TV. so the quality is probably allot lower then I thought. Thanks,
Tom
