dvd shrink ?

[Dutchmaster420]

i have compression settings on auto and am re authoring for just the main movie


the percentage is coming in at 72.9%

this is my first time using this software or any doing this.....will this still be great quality and look like a dvd?

would there be a noticble difference between the actual dvd and after dvd shrink?

Yes, almost always with dvdshrink. Check out this link here: comparison

It compares various encoders and transcoders (with pics). Dvdshrink is a transcoder, which means it compresses the movie quickly, but at a loss in quality. The best method you could use is dvd-rebuilder + HC encoder. It will take a little longer to do, but the difference is worth it.

edit: when looking at the pics notice how blocky the dvdshrink pics are. The HC encoder pics are much better although they do still have 'mosquito' noise.

You might want to set the compression settings to manual and compress the extras as much as possible, I wouldn't mess with reauth, it takes a while to do and not worth it if you want menus to work.

72% isn't that bad of a compression rating, you may notice some blurryness/artifacting. If this really bothers you then get some dual layered disks and then you don't have to compress at all.

do it and find out. heh.. every movie is different. on my standard tvs... looks fine most of the time as long as it's ~65%. Sometimes it's noticable, but there's only so much you can do if you only want to use 1 disc single layer backups... gotta give something up.

I use DVDShrink all the time and the quality is pretty decent. There are settings within the program to improve the quality but most people can't tell a good DVDShrink copy from an original DVD.

You can sometimes cut off the ending credits too to improve things a bit.

If I'm getting below 70%, I will tend to split onto two discs, especially if it's a movie I think I'll watch an above average number of times.

Some DVDs are crappy enough to begin with that it's not going to make a whole lot of difference.

 

[Super56K]

I'll say it once more. If you care about your backups don't use dvdshrink at all. Dvd-rebuilder + HC encoder is the way to go. The longer the movie, or the more compression, the more important it is to use a quality encoder. The program has the ability to heavily encode extras to give more space to the movie or strip them completely while keeping all the original menus. It will even re-encode menus greater than 50mb.

I use the settings "Deep Analysis" and "high quality adaptive compensation" set to Sharp in dvdshrink. I use it because it's quick and free and I can't afford Cinema Craft encoder =(

edit: Forgot to mention I always compress the hell out of the menus and extras, and yank other language sound tracks (i leave DTS if the movie has it)

You can't really tell the difference when viewing on a SDTV.

DVD shrink is a fast easy way to make a decent quality backup. Yes there are beter ways to do it but not in 20~30 minutes. I can hardly tell the difference between a ripped and real dvd. Most of my collection was ripped with DVD shrink and is now in a box.

I used to use the CCE method back in the day, but with dual layer blanks at $1/each is it really worth it? I don't really burn anything anymore, but it doesn't seem worth it to me.

Where do you buy them for $1 each? The last time I bought them for $1 each was 20 verbatims from Newegg after a $10 rebate a while back. I haven't seen them that low since.

alright it to 79.4% using dvd shrink using reauthor just the movie and cut off the end credits

so this should be great quality right

also where can i get cheap dual layers....best ive seen em for is about 2 a pop


im going to look into dvd rebuilder also

How big is the screen you're going to be using... and more importantly what's your viewing angle on it?

If you're got a large viewing angle, it's going to be a lot easier to pick up on defects that might arise from this. I'm at about 40 degree viewing angle and I'm usually not bothered by the kind of defects I get when I use ~80% on dvd shrink.

I could put more effort and time into backing up, but I'm lazy and I get pretty good results already.

My end results have tended to vary a great deal on the original quality of the DVD as well as when I've compromised on compression settings.

Sitting 5 feet away from the hitachi would be equivalent to the viewing angle I use and I'm pretty satisfied with my results... maybe I need to get my eyes checked though

With single layer discs as cheap as they are, I'd say to ahead with your ~80% copy and then you tell us how it looks.

are dvd-rs from newsgroups good quality?

 

[Dutchmaster420]

i got the matrix to go at 93% so that should come out nice.....

Scene rips are multipass CCE encodes. So PQ is still very good. Small groups or individuals posting stuff is usually done with DVD Shrink. So there is definitely a quality difference between the two. Best example is the XMen 3 image posted recently. The n00b used a trial version of a DVD authoring tool and it had a watermark on it.

That has a lot to do with the dvd's original bitrate. Say you compress a dvd with an average 8.0 mb/sec bitrate to 60%. That gives you around 4.8 mb/sec, and there isn't a huge difference because the quality level is still high. If you compress a dvd (say an older movie) with a bitrate of 4.5 mb/sec to 60% you end up with around 2.7 mb/sec which is usually considered unacceptable because that's getting into divx/xvid territory.

I've gone down as far as 60% without noticing anything of lower quality. But I'd say putting the menus, extras and whatnot at custom, and sliding it as low as possible. Also, remove the subtitles and extras in languages you'll never use.
