DVD Compression Quality

[louv68]

What is the best program to compress a DVD9 to a DVD5?

I know that DVD Shrink (which is an awesome program by the way) can
do this, but I'm looking for the best output possible. I want to
backup "Pirates of the Caribbean" whose running time is 143 mins. If
recording onto a DVDR which can optimally hold 120 minutes of video;
how much quality will actually be lost with the additional 23 minutes?
Will the loss be apparently visible? I will be putting only one audio track
and removing all menus, subtitles, etc. Will I actually be better of splitting
into two DVDR's?

It's about quality, not quantity!!!

Did you try DVD Shrink out? How did it look?

I used shrink to backup Apocalypse Now (194 Minutes!) and it had no significant difference. I guess that by using a magnifying glass you would see a difference on a 54" screen, but are you going to watch it that way?

or, you could instead burn the 1 movie onto two blank dvd's using dvdfab or something similar.

What was your compression ratio on Apocalyse Now?

[jurynel]

DVD Shrink 3.1 had it 55.3 %

For long movies InterVideo DVD Copy produces the best vid quality of the bunch. Once you start dipping that low the difference between it and Shrink is very noticable.

Give the trial a shot.

i've heard rejig has better quality than shrink(just heard, don't hold me to it).

. . . but then by the time I've posted this thread, I am sure some new software would already be available to do even more, better and faster . . .

The safest advice would propably be - try every thing you could find, and stick to the best for a day or so. Then start over, because it would be obsolete by then.

i use dvdshrink - when i go under 65 i start to notice a difference

If its about quality then you dont want to use a transcoder at all but instead a reencoder.

Look into either DVD2SVCD (inDVD2DVD mode) or DVD2DVDr. Both use CCE which is WAY better then any transcoder. But it takes a long time for the trade off.

DVD2DVD-R with CCE!
Brilliant results on movies that required compression over 60%.
Prob is it does take a considerable amount of time - 3,4 pass VBR might take as long as 12 hrs on my setup.(P4 1.8 GHz, 1 Gb RAM). The outcome does reward for the time taken though. Spot on picture on my Phillips 32'' widescreen.

Good Luck

I checked out Rejig . . . for me it made history.

First time in my life I get voice/pic Sync problems.

But then the pic quality does seem te be OK.

I Use Pinacle Instant Copy 8, this Is The best For me. Best quality, No pixelation imagens And very good image quality.

Is possible to keep more than an audio track and subtitles using the Dvd2dvd-r?

i'm trying to compress a DVD from my HDD but i don't think that DVD X COPY allows me to load vob files from the hard drive... any way i can load them in?

I cant see what your problem is. I backed up POTC onto a single DVD+r with DVDShrink (re-authored and dumped everything except main film and audio) and the quality is excellent.....just do it.

[guns1inger]

I used Nero Recode 2 to backup POTC. Dropped all but the movie+DD5.1+commentary tracks, then killed the end credits. This shortened the movie by a good 10 minutes. Final compression was to around 92% if I remember correctly. Very happy with the result.

yeah what he said... i just burnt it DVDshrink with no fiddling and it was perfect, didnt notice a thing. But that was with the 2 dvd edition with the bonus dvd having the extras... if there is extras, i dunno, just compress them more and see how u go

I concurr...Nero Recode 2 did a very nice job of Pirates. I recommmend trimming credits at all times, and dropping commentary etc... It's all down to encoded bitrate and not running time. I have a couple of region 1 dvds that are pushing 2 hours but just barely fit a 4.7gb DVD. One good thing about Recode (and I'm sure other programs) is the ability to specify the output file sixe. Most of my dvd-rs are 4850mb in size, and I stipulate this to make most of the disc. No overburning, just using what's there.

[MrShavez]

How can you get 4850mbs to one dvd-r...it is impossibel to overburn a dvd-/+r so just wondering how you´re able to manage this feat?

And I always thought a dvd-r can hold ONLY 4700mb. Guess I was wrong...

jurynel. u had 50% compression with shrink and u say u couldnt see any significant difference? u must be watching it on a small picture tube tv?

i mentioned this in a post i made a while back.. but i suggest people who give their opinion on quality let us know wat kind of home theatre system they watch their backups on..

because compression lower than 80% on shrink is something u can definitely tell on plasma, lcd, DLP HDTVs using component/dvi connection.. some might even see the difference with anything from 80-90%..

i personally made a 1:1 backup of chapelle show season 1.. each episode was compressed around 60-70% i can't recall.. anyways.. on a regular 36" sony picture tube tv connected using s-video.. u could not tell the difference and looked very clear.. however.. watch it on a 56" WS HDTV using component.. u can see major compression..

anyways.. i would only use shrink if ur not really picky about quality.. and the movie doesnt dip below 80%.. i would also recommend checking out instant copy (ic8).. the quality is better than shrink wen it comes to movies which need a lot of compression.. however i dont guarantee that it will be like the original.. like i said it depends on ur equipment..

if uw ant the best possible quality.. re-encode.. use dvd2svcd (dvd2dvd) and cce..
