ok i'm sorry if it was asked but i did a search first and couldn't find this question. what is a good ratio to compress it. i wanna back up my family guy DVDs (seaosn so they have episodes) so i have to copy the whole disc not just the feature cause there is 7 features on each disc. i took out all the extras, non english languages and sub titles but still wound up around 79%. i guess the question is what is the worst ration u can get away with w/o losing too much quality and also is there a way to get better quality out of each disc by using the quality check boxes and so on. it takes about an hour to do a full DVD for me. i have a intel celeron m 1.4 ghz processor(its a lap top) and 512 MB DDR ram. so its not to bad but by cheking the quality button its like 2+ hours to rip. buring is quick cause i hve a 16 times burner i believe but discs only go 8x so i burn at 8 speed. any help would be greatly appreciated. also the more i learn the more i can stick around and help people here as well. i know i'm a newbie so go easy on me. thanks

79% is a pretty good compression ratio. I heard that if you keep the compression above 60%, then it should be OK. Anything less than that is very noticeable.

Deep Analysis and Quality Enhancements in Shrink will give you better playback quality and they are based on the amount of compression. The Default in Shrink is Sharp and you can use that up to 80%, use Smooth to about 65% and Max Smooth for anything below. It is always good to do Deep Analysis below 90%. Also if the disk is big it is better to rip it first with Decrypter and then proceed to use Shrink, less stress for Shrink, it is not having to access the disk just the HDD.

Are those setting accessed under preferences?

They are accessed once you hit the backup button in Shrink, if your compression is below a certain percentage you can check the boxes, however if they are greyed out then you do not need them. Once you set this setting it will remain until you change it.

Thanks Arniebear!

Ok thanls a lot for the info. I do use dvdencrypter first then I open image in DVD Shrink. I shrunk one at 68% ratio and I used sharp and I cheked off both boxes In the quality settings and it came out perfect. Is it better then to use smooth next time I do one at that ratio? The only reason I asked is the total time to deep analyze and the other quality check box triples my total time to get it to the hard drie form about 45min-1hour to about 2-3 hours. Once its ripped I can burn it in 15min at 4x or go to 8x and do it in 8 (but I don?t cause I heard it will skip. Also I have Memorex dvds. I heard there no good here is that true? And if so what name brands are the best? And again thanks for all your help and info

Not exactly the best, if you plan to use these up stay at the slower burning speed and make sure you set your target size to 4300 to 4334 so you do not burn to the edge. On your next buy try Sony, Verbatim, Fuji [MIJ] or Maxell, they are all retail and much better media. If you are an online buyer then go for Taiyo Yuden, which I prefer the best. You can get them from the reputable online dealers

As for the compression 68% at Sharp will still look good, it is all in the eye of the beholder. For large compression I use DVDRebuilder which I feel does a much better job on compression.

Here is a good place to look at the quality of media, which will help you decide, it is older but still applies.

As for why Taiyo Yuden are so good I will send for our resident Doc Ty, or member kivory666 and ask him to explain.

hi,
just got the message from my buddy arniebear, it's like a hospital for me HERE @ AfterDawn, i get "paged" by one of my friends, and BAM i head directly to where i need to be :)
well, first of all, regarding Taiyo Yuden media, one of the MAIN reasons that the quality is superb on them is the dye that they choose to use to manufacturer their media~ :) it is the highly coveted genuine AZO dye that goes into their discs, this is one of the MANY factors to consider when purchasing blank media...Verbatim is also another manufacturer/brand (Verbatim is the BRAND, MCC or Mitsubishi Chemicals Corp. is the manufacturer, they ALSO utilize this AZO dye in their media) :)
secondly, many people around here regard the "MADE IN JAPAN" media to be better than the "MADE IN TAIWAN" stuff, THIS IS GENERALLY TRUE, however, there are ALWAYS exceptions....personally, the Verbatim that i use (ALL made in taiwan) as well as the Ritek Ridata (also made in taiwan) are GREAT quality media...i have had countless flawless burns using these 2 brands, BOTH MADE IN TAIWAN, with great results. but, if shopping locally, other than these 2 i mentioned, i would STRONGLY suggest finding the ones that are "MADE IN JAPAN" :)
here is an excerpt taken from the description of Taiyo Yuden:
Quote:
Taiyo Yuden's 8X speed DVD-R disks provide exceptional quality for general use and feature silver thermal surface configurations. The extraordinarily versatile 8X DVD-R media can be used with the new higher-speed DVD writers from Sony, Pioneer and other leading manufacturers, as well as upgraded 2X writers from Apple, Pioneer and others.
Top-Notch Performance Reliability and Archival Life!
Taiyo Yuden 8X DVD-R disks offer 4.7GB of write-once storage capacity and superior recording quality. They provide the highest level of performance, reliability, and archival life. In addition, Taiyo Yuden DVD-R media deliver broad read compatibility with the vast majority of DVD-ROM drives and DVD-Video players in use today. These affordable 8X DVD-R discs offer exceptional solutions for a wide range of applications, including home and professional video recording, DVD content development, DVD duplication, PC back-up, and data archiving.
as generic as that MIGHT sound to you, when dealing with AUTHENTIC Taiyo Yuden media, it is in fact 100% TRUE~ assuming you buy from a reputable dealer, Taiyo Yuden media is BY FAR the BEST QUALITY media you can get and with the frequent sales locally or online, they are NOT more expensive than the crappy stuff (ie. Memorex CMC MAG manufactured media, HP, Philips, TDK, among MANY others that use CMC MAG as their manufacturer, ALL these brands DO USE CMC MAG throughout their different rated speeds and formats, so, BEWARE...do NOT purchase media with the above names and you won't get "burned" in the future w/ skips/pixellation/freezing/errors on your backups)
also, i know for a fact that Taiyo Yuden has one of the MOST STRICT quality control standards at their manufacturing factories, all their media sold to the general public MUST meet or exceed their stringent standards or else they are DESTROYED, deemed "not usuable" by the average consumer~ :) very few companies have such high standards, MANY other companies simply care about making the most amount of $$$ for every single piece of media they sell, whether it "passes" the quality control tests or not, they ONLY care about PROFITS and more $$$ in their pockets, hence, the CONSUMER (you and i) SUFFER and are left with crappy quality media that degrades quickly over time, only to be left unplayable in the future or more commonly called, a "coaster" :)
so, that is the basics of Taiyo Yuden media, i can go into more depth and detail if you would like, but, i think this should be a good start for your media BUYING needs :)
below is a link on a good price for REAL/AUTHENTIC Taiyo Yuden media from MY personal favorite online retailer....supermediastore.com~ :)
it's on sale right now for these GREAT TYG02 coded 8x dvd-r media~
http://supermediastore.com/taiyo-yuden-silver-thermal-8x-dvd-r-me...
it's a 3 day sale, so HURRY if you want to take advantage of this great price~!
good luck and happy burning, ditch the Memorex you are using now, despite the compression, burning onto GOOD/HIGH quality media will ALWAYS ensure better video playback and longer lasting media life~
docTY~
good day to you all~
Recommended Media:
Taiyo Yuden 4x dvd-r TYGO1/ 8x dvd-r TYGO2/ 8x dvd+r YUDEN000T02/ 16x dvd+r YUDEN000T03
Verbatim 8x dvd+r MCC003

Thanks for the info. When I buy more I?m gonna try those ones. I have the so called crappy Memorex and have burned about 10 DVDs with them (including compressed season discs) and they all came out perfect.
