Why is DVD quality so bad?

Recommended Posts

Sensayshun    0

I recorded some films onto my computer. But the quality is pretty awful. I happen to know next to nothing about media, i've been hanging around on this thread for about a week now and have learnt lots but I can't work this out. I do a direct copy from the DVD and it takes about 6 hours but as soon as i put the film to fill the screen or any large size the quality is pretty poor.

What's making the quality so poor and how can I fix it?

TIA.

What is the source of these films? Is it a video camera, DVD, VHS/beta, etc?

um, you could try DVD Shrink if the size is more than 4.7 GB, but what software are you using actually? That stuff can make a difference.

Are you encoding the file into anything like Xvid or DivX ? Or are you doing a direct dump of the dvd because im sure that wont take six hours. Try a proram called Dvd Decrypter search for it on google, that dumps dvds.

I'm using some shady software :$

I don't think i'm converting it. Sorry I know nothing about media.

It's not for than 5gb because ht ehole folder has 3 films in and it's less than a gigabyte.

It's the compression, then. You are encoding it to low quality. If 3 films fit into less than one GB, that is some insane compression going on.

How do I make it so it doesn't compress at all?

I tell it to make the file size infinite (however much it needs)

if you just make backup of your dvd disks, then use dvdshrink (freeware)

it will convert them to fit onto a 4.7GB dvd disk and the quality will remain high

if it's backups like everyone said use dvdshrink. remove unwanted subtitles and sound streams. normaly i don't have any subs and only have the 5.1 ac3 sound stream, sometimes i have to keep a few because of the menus.

Ok. I downloaded and used DVD shrink. I guessed what to do and I got this small box that played the video and told me it was encrypting it and how long it had left.

That all finished and now i'm left with a load of files ?

And I can't play them because they're all unrecognised formats.

Any ideas?

DVD in its nature is compressed, if you are trying to shrink it onto 1 700MB cd, you are going to get worse quality or at its very best the same quality as the DVD.

I read an article (wish I can find the link) where a Film Editor can not wait for HD-DVD, he says that what he sees editing and what we see (from DVDs) are vastly different. He states that one reason is that DVD must compress 90 to 95% of the video quality to fit it on a DVD. He states that HD-DVD doesn't have that hinderance. He believes that once people see HD-DVD with a television that shows off the ultra sharp quality, people will never go back.

He states that it is so sharp you can see the make-up that actors uses (in terms of where it begins and where it ends), also you can see small little mistakes (an example he gives is that in one of the Star Wars films, someone left an umbrella in the background, with dvd you can't see it but with HD-DVD you can).

I for one can't wait for HD-DVD, Quicktime 7 uses the same codec I believe, and from what I hear the dvd players will be backwards compatible with current DVDs. And lastly, I hear that Sony has been coverting all of its movie ownership onto HD-DVD. Expect 2006 to be the year of HD-DVD.

what software are you using to play DVDs? DVD Shrink will give you a bunch of .vob files and some in other formats. you can use a software like PowerDVD to play these vob files. or if you have a dvd burner you can make backup discs for your movies.

DVDs are already pretty low quality if you have a high screen resolution. Modifying the file only makes it worse.
