Quality on burned movies?

[iiss]

I'm been wondering for a long time if ripping and then burning the movies to DVDR changes the quality on the ripp? Is it identical with the orginal movie? With identical I mean same sound and the same film quality. Or are ripped movies lower in quality?

Thanks in advance!

Ripping the movie with DVDdecrypter will not change the quality at all. It's when you have to compress it to fit onto a single layer DVD recorder, that you start to lose quality. The more compression, the less video quality.

Ripping has no effect on Quality. Only transcoding or re-encoding the dvd will affact quality. When compressing with a transcoder i.e. dvd shrink, the sound is also unaffacted. the audio is never compressed, it remains the same, (unless you re-encode the movie)

To minimise quality loss, try stripping out the extras using either vobblanker or titlesetblanker. strip out any additional audio like the directors commentary.

Or you can retain 100% quality by splitting the movie to burn on 2 dvdrs.

Thanks for the answers.

So if I ripp a movie with DVDDecrypt and remove the extra stuff (like different subs, audio that I don't need etc), the quality should not change anything? Or do I need to compress the movie even if I remove all extras?

When I ripp a movie I start with DVDDecrypt and then I use DVD Shrink. So if I remove the extras, there should not be any kind of quality loss?

well, not really. depends on the dvd, it varies.

remove extras such as bonus features, trailers etc.. as well as any additional languages.

thus will minimise the compression needed. you will lose some quality, though it will not be much noticable.

Use advanced settings in dvd shrink, like deep analysis and quality enhancements, this will reduce quality loss.

Like i said, it varies depending on movie.

Gee, maybe you should look at what you are doing. If after removing all the extras as you call them, the file size is still too big, if using the last released version of DVD Shrink and it is set to automatic compression, you can see the percentage that the file must be compressed. Then after burning your back-up pop it in your player and try to compare with your original. Your eyes and ears will be the judge. This is not rocket science. Asking us to tell you how your back-ups will sound and look on your equipment is utter non-sense. This site is full of information if only folks would take the time to research and read.
