DVDShrink 3.0 Compression

[judgmentday]

Which would be a descent percentage of compression for movie only?

No compression is the best
85%?
75%?
65%?
55%?

Which one is not acceptable at all?

Thanks.

I'd say don't go below 70% and if you have to then use dvd2dvd or something of that nature.

You are the one that has to watch it.
Why don't you see for yourself.

I backed up a 2 disc movie at 50% and it looks decent on a 50" Rear-LCD widescreen. I saw only small pixelation around the moving features if I looked from less then 5 feet from the screen. Usaully I try and stay above 60%.

As already said, stay above 70% with DVDshrink. Anything lower, use dvdone, it yields better quality. If your going below 45% - 50%(DVDshrink), then you may strongly consider re-encoding the movie unless you are fine with the extra artifacts introduced with such high compressions.

Foo, I really do not appreciate your response.
You did not help me at all.

Also, I want to thank all the other individuals who responded in such a positive way. It really helped me.
We need more people like you guys in this forum.

Again, thanks a million!

Sorry
Looks like my comment was wasted as you apparently still don't
understand that you essentially asked other people what YOU
would like.

If you would like some links to the mostly failed attempts at
objectively measuring video quality , i can find some .

Judgement, don't mind FOO, he's an a*#hole anyways! I'd agree with the others on the level of compression. I've never had to use anything below 65% (Titanic), so you should be fine.

I agree with Foo.
The only way you will know is do it for yourself and test on your equipment. Unless your making copies for others (illegal) it should not be that hard to do!
Much depends on your source, players, TV ect, how good or bad it will look.
Basically stay as large as you can but still make it fit is the only correct answer, unless you either want to make 2 disks or forget the whole thing!

I did TITANIC at about 30% of original size and it looks goods!

First I captured both tapes at 8,000bps. Way over kill! Then I made 2 DVDs (about 6gigs each) shrank both to fit a DVD -R and made a 2 disk set! Then I took those two DVDs and made a DVD9, which I then shrank to a DVD5 and put on one DVD -r. The end result was a good looking movie I am happy with! 12gigs shrunk to 4gigs!
That was an experiment, I was actually expecting to toss the final one disk DVD, but it's good enough to actually be happy with!
Since I use cheap disks, I consider a disk as 4gigs for my use, I stay back from the edge some. I may not need too, but I never had problems or waisted a whole disk either.

Lord of the rings, both movies are 3Hrs. I did both movie DVDs, full backup (minus extra lanauges) at default settings with Shrink 3beta5.
Can't tell the difference if you don't see the disk! I don't bother with the extra disks though, just the ones with the movies.

Maybe if I sent my disks to you or others, they would look terrible on your TV?? Mine they look great!

Hi overloaded_ide,

I applaud your experiment. I'm sure you had lots fun doing it.
I have not had the chance to backup a 3hrs movie. I think that I would just split it into 2 dvdrs with DVDShrink @ 70 ~ 80% compression.
I'm sure that there are ways to compress a large movie to fit it into a DVDR but it requires lots of work, time and imagination to do it.
I'm sure that someone would come with a way to fit a 6GB movie into a 1.44MB floppy disk with a killer compression method without loosing quality or complete unnoticeable loss of quality.

It seems that most of you agree that about 70% compression is acceptable using DVDShrink and just the movie. The quick way.

Sorry

Dear FOO, I forgive you.

understand that you essentially asked other people what YOU

Sure, everything that may help me, definitely will be appreciated.

[FOO]

Thank you. I'm not trying to be mean, just accurate.

Managed to pick up the beer yet, FOO?

Actually you can backup the entire disc as long as the only movie is compressed to 70%. Just compress the menus further if need be.

I got you.

I think you missed my Titanic point somewhat. I could easily have captured the 2 tapes at the correct bit rate and made 1 dvd! Heck in one shot I put Felowship of the Ring on DVD r, and Two Towers on another! Those 2 were DVD backups. Just shrink and burn! Each is a 3 hr movie!
To compress a large movie to fit it into a DVDR it does NOT require lots of work, time and imagination to do it. One shrink and burn, same as any other! No comercail DVD is ever larger than 9gigs per disk, so most you ever will need MAX would be 50% and that would be very rare!

No compression is the best
85%?

In answer to your first post, that is all the opion of the person watching, and the source you started with! There is NO correct or best answer!
With my Titanic example, I got probably close to 30% the original size, or compressed 66% and it is still good!
No compresion is the best choice, then follow the list! The least compresion required to fit on the desired number of disks is always the best answer! If there is one!

I am only willing to do one disk per movie normally. I just don't want to wonder where the second disk ended up when I want to watch a movie!
I'm not to lazy to change disks, but with kids often they aren't put away. I don't want to get to the end of a first disk then find out I need disk 2 and it's lost! SO whatever fits and still looks good!
If you want to do 2 disks, then you need no compresion at all and should even have space left over! AT MAX a comercail DVD disk is only 2x the size of a DVD R, so you will never need more than 2 disks to back up one disk!

The exception to the above would be a movie that does not end! Fellowship of the ring, and Two towers have no ending, they just continue to the NEXT movie. So those I could just find a good spot and cut to two disks anyway. They fit and looked perfect on one disk though, so no need to!

I saw nothing wrong with that reply cuz IT TRUE....you're the best judge...something that will look great to one person will look unacceptable to another.

I just watched Ghost Ship at 15% compression on my 65" Mitsu wide and it looked great...and to regular folk like my wife...she said it looked like an original dvd to her.
