Highest Quality w/o Compression? quality, previously, apologize, meaning

andy

When using DVDShrink, is the native quality of a DVD reduced in any manner when the DVD is backed up with compression set to 100% (meaning no compression)?

I apologize in advance, as I am sure this has been previously addressed, I was just not able to find it.

Hi!

Nope...

Welcome to Doom9.  In over a thousand burns, I have not noticed any degradation when no compression is used;  and up to a certain amount of compression, there is no noticable quality loss.

Enjoy your stay,

When you tell DVD Shrink to use no compression on a titleset, it meerly copies those VOBs over to your processed files.  The only time it changes anything with quot;no compressionquot; selected is when you decide to remove audio and sub streams... but the video source itself is always left untouched; the only thing processed in this instance would be the removal of the undesired audio/subs.  Which all means that what you keep is a bit-for-bit copy of your source material.

Some people use DVD Shrink in this matter for pre-processing before running a program such as the free version of DVD Rebuilder.  If you wanted, say, a movie-only project -- but want Rebuilder to do all the video processing -- you'd first use Shrink to create a quot;no compressionquot; movie-only project... then feed those files into Rebuilder.  Of course, the Pro version will do this automatically if that's what you tell it to do; but for the sake of this discussion, that's one possible use.

Thank you all of you very much.  The experience and intelligence drifting around this forum could power a small country.

You will, however, get some kooks coming out of the woodwork claiming that all kinds of adverse effects have been noted when not compressing... but they are, as previously mentioned, kooks.
