  1. Just wondering for a quick answer here. I'm new to backing up dvds and such... but in DVD Shrink what percentage should I strive to get in the main movie to where there's little loss from the original. In other words what's a good percentage before noticable loss occurs?

    Unfortunately qualitative questions like this are very hard to answer because there are so many variables and so many different playback devices. THe exact same movie at 70% may look no different from the original on a 27" TV yet on a projector or rear-projection TV may look terrible. Throw in that you might have lower standards than I do also.

    As an off the cuff magic number, If it's less than 85% then I do Deep Analysis. I do main movie only for my backups unless they are music DVDs where you need everything. I have found this to be acceptable for me.

    The only concrete advice I can offer is to remove all the audio that you will never listen to. This will give you more space for the parts you wish to keep.
    If in doubt, Google it.

  3. Quick answer? Man, you have no idea, this question is a hardy perennial that sprouts up every month or so. :P But a new version of DVDshrink has come out since the last go-round, that might change opinions a bit. Just don't expect a consensus.

    Okay, I'll bite. Before the latest version, I would've said 80-85%, but that's really looking hard. Lots of others have claimed they detected no difference below 60%. Also, I don't do DVD backups very often anymore, and when I do, DVDRebuilder is my preference. So I'm biased, I'll take re-encoding over transcoding any time.

    The latest Shrink is an improvement on an already great program, though. Force me to answer, and I'll say you're good to at least 70% unless you're extremely picky. And know what to look for... JMHO
    Pull! Bang! Darn!

  4. lol, hopefully it doesn't open up a can of worms. To tell you the truth I was quite happy with the quality I got from taking an avi re-encoding it to play on DVD... I did this with two movies and only covered about 2/3rds of the DVD and I was happy. perhaps I should re-encode I dunno. I'll do a little of both and see what both look like on the computer and see if I see a difference.

    Thing is the movies I've plopped in so far... Seven Samurai, Indiana Jones Raiders of the Lost Ark the movies themselves are like 7000+mbs and dvdshrink makes it go to like 67% I'm just not sure if I like that number or not. But thanks for the heads up.

    Not below 70% unless I really want the extras. Almost always Reauthor.

    EDIT: Below 70% I would recommend the deep analysis option.

  6. even when I just re-author and throw in the movie and the audio I'm still usually in 65% or so. I could care less about the extras really.

    Once you've done a few Shrinks yourself...all from different original DVD's....you will realize that the question is un-answerable.

  9. Only good answer is what ever trips your trigger

    Long as your happy with it. So many variables, equipment, the actuall movies, etc..

    Go for what ever fits the movie is really the only answer also. I mean if you want it all on one disk, then you have the option of going to that level of compresion or if to low just not doing it at all right!

    I have gone really low and not been able to see a difference on some movies. Most often I shrink the extras and menu's as low as the program will go and then have as much room as possable for the movie itself. I watch a movie often, extra's only once in a while.
    In reality I often can see no or little difference in a movie that was not compressed at all and the extra's that were maybe 50%
    Sometimes I do get fuzz or blocks in the extra's a little, I think I did some at like 35% once recently and wife noticed them in the extra's but said they weren't too bad.

    For the main movie I do my best to stay above 80% anyway, but I do what ever fits and always been happy.

    I personally strive for 80% as far as good answers go..
    Thanks

  11. I got around 75-80% with Conan with deep analysis I believe and towards the end of the movie the compression got so bad that it wouldn't even play... wtf?

    Having backed up now around 700 DVD's (I own them all, of course), I *ALWAYS* do deep analysis, what varies the most for me, is if I leave off the extra "sharpness/smoothness" option...I find that max smoothness is best if I'm around 50% or so...above 80% I do sharp, and if it's like 90%+, I use maximum sharpness.

  13. Well, after DVDShrink pissed me off when I was at like 80% and would hardly play the end because of compression issues I've started using DVD ReBuilder. I quite like the results I'm getting though it seems like one I start skipping to later chapter of a movie it hangs up, however if I just let it play it'll play through. Bit odd if you ask me. Also odd how much of a movie will play on one dvd player very smoothly up to a part where it will start jittering around or stop completely, and on another player will play that part just fine.

    lol I should just fork over for a dual layer.

    Sounds to me like your media and its compatibility with your buner and/or your players is the issue.

    It has NOTHING to do with the compression used
    If in doubt, Google it.

  15. Jimma's right

    I got that probleme sometime the end of the movie is fucktup.
    But nothing to do with dvdshrink, I use cce with dvd2dvd and got the prob there to. But let say i've bacup about 400 dvd (that I own of course) and get let say 10 disk like those. So the probleme can be the disk, the burner or I don't know.

    I'll give my answer to the main question : try to stay above 80%, If you need to go below use dvd2dvdr with cce and re-encode in ONE pass, yes I SAY ONE PASS, if you do many pass the movie will get Foggy. It will take sometime around 3 hours to do the job.

    Dvdshrink is top by the way...

  16. I always use the deep analysis function. If the movie is 80% or above, I set AEC to "Sharp (default)" and below 80% I set it to "Maximum smoothness". This adds a lot to the encoding time but results in a greater quality at lower bitrates.

    The most I have ever compressed a DVD is to 64%, and it turned out nicely with AEC on maximum smoothness.

    This is very much a personal thing - some people simply aren't happy with high levels of recompression whereas some people will watch VHS-quality video no bother.

    Yeah I got to thinking about that also. They're like no name brands so that's probly definently it. I was supposed to get KHypermedia and they sent me no names ... I still don't see why a whole movie would play perfect then towards the end turn to shit.
