size issue with some movies

[slorente]

I am trying to backup some of my DVD's for archival and can't figure out why some of them are still 6GB after stripping them.

A perfect example is The Bourne Identity. I decrypted it to my hard drive and then stripped EVERYTHING but the movie itself with IFOedit. All I kept was DTS and 5.1...got rid of all subtitles and 2-channel audio. The movie is still 6GB and I have to compress around 25% to get it to fit on a DVD-5. Is there anything else I can look to strip out of it? Is this normal for a movie under 2 hours?

Thanks in advance!

Sure it's possible. The manufacturer/producer of the movie probably encoded the movie at a very high bit rate, therefore requiring lots of space. The only way to get it to fit down to 4.3gb is re-encode (compress/shrink). Is it normal? More often lately.

Thanks padre! I am doing a test run with Nero Recode2. This will be a true test to Recode's quality loss at compression rates under 80%.

I have done multiple tests, all with around 85% compression, and I can't notice any difference in quality between Recode2 and the Magic 3. However, we will now see! :D

Don't know about Recode2 or Magic 2, but I've done lots of re-encodes with InstantCopy and DVDShrink at as much as 65% and not noticed anything bad. It all depends on the type of movie (action, fire, movement) and the amount of dead area it can compress.
