HI everybody

I know the subject has been discussed several times , but I need to know answers about compression and dvdshrink

Can u tell the me the compression limit to use, in order to have no artefacts and to have a copy as close as original DVD

Please shrink users tell me about your tests on this problem

Thanks

hi
i just made a backup of exorcist using dvd shrink, after compressing the extras to 30% and removing all subs but english. In addition i also compressed the main movie to 30%, the quality of the movie is almost identical to the original. Thus im

hope it helps

its all in the eye of the beholder.

I have used dvdshrink on the option right above still picture (10) on Star Wars II and a few others and it looks fantastic on my 32in toshiba (2003 model).

Since I do movie only, I just use the compression that will allow me to fit just the movie (no beginning or ending credits) AC3 english audio and english subtitles.

No artifacts is up to shrink and the movie (ie the original will have them). Since you want to get as close to possible to the original, maybe nothing below a 2 or 3, but again, I have had great success with higher numbers. Since it sounds like you may be having some issues, you might want to try IC7. Takes a long time to encode, but people have reported better results than using higher end shrinks.

Thanks guys

If others could help me more , just do it

Brush--

As a person who has recently just begun playing around with the different compression levels on DVDshrink, let me offer a little bit of information on what I have found out:

As macleod said in the post he just made, I too only do "movie only". I have compressed at different rates, and I firmly believe that quality IS in the eye of the beholder, and it all depends on how PERFECT you want the quality to be. Here are the results of my most recent tests (last night, actually):

1) Used DVD decrypter to backup all files from the Lord of the Rings: The Fellowship of the Ring original fullscreen version. After ripping all files, I opened up DVD Shrink and went into open files, and opened up the image I just created. Then I went into reauthor, and selected the main movie only. It was way too big for one disc, and I wasn't that concerned with quality, so I thought I would try big time compression. It took level 8 or 9 (I'm sorry...I can't remember exactly) to fit it one disc. I watched about 30 minutes of random parts of the movie, and there were only 2 parts that you could tell the difference in quality, and I have a 27" flat screen and was sitting about 3 feet away from the screen. If you are familiar with the movie, here are the parts you could notice a slight difference: When the party is running through the Dwarf caves and across the bridge, Gandalf has a shown down with a big fiery monster called a Balrock. On the bridge, Gandalf and the monster have a showdown, and their is lots of light and fire and action, and here you can tell the quality is lacking slightly. The other scene is at Bilbo's birthday party when Gandalf shoots of the fireworks. There is a ever-so-slight loss in quality. This was my first backup at such a high compression level, and I was quite impressed.

2) Backed up Sweet Home Alabama at level 4. Watched it. No noticeable level of quality loss.

3) Backed up Gone in 60 Seconds with some extras at level 6, and there was a lot of action in this movie. There were a few spots (about 4 or 5) with minimal amounts of quality loss, but nothing major.

A few points to consider...if you are watching backed-up DVDs on a 60" HD widescreen, you will probably notice MORE minor defects than I did if you compress over level 3 or 4. If you are not that concerned with 110% perfect quality, try experimenting with lower levels. I did, and I have been fairly pleased. Everything that I have read says that you will only notice slight differences in quality for stuff level 6 and above. Anything 1-5 should be damn near unnoticeable.

Hope this helps. As always, this is just my honest opinion.

I used DVDShrink to re-encode Dario Arento's Phenomena DVD...I chose level 8 Compression as it was the only level that would allow the whole disc to fit to a DVD-R as its a rather big DVD-9. The end result was nearly identical, as the original source wasn't the greatest transfer in the history of DVD's, so it all depends on how the original source looks I suppose? I did a level 5 re-encode of Lord of the Rings: FOTR and it didnt look EXACTLY like the original, but it was close enough for my tastes, and my current TV setup. I advise purchasing a DVD-RW and toying around. I use the DVD-RW that came with my drive to test re-encodes before burning to a DVD-R, just to make sure it is watchable, otherwise I play around with the files a bit more till I get my desired result.

It really depends on the quality of the original, and how much of the bitrate used for it was "wasted".

I've seen movies that are 8GB for just the film that look almost identical when shrunk a full 50% to fit on a DVD-R. There just wasn't that much to the movie in the first place.

Then I've also seen movies that are 4.5GB and when you shrink them to 4.0GB they look pretty bad.

The next question is... will you notice the difference AT ALL? If you have an average 27" TV and an average DVD player... probably not. I see it, but I'm a video geek.
