Is DVDshrinks Deep Analysis&compensation worth the time?

[Super Warrior]

Normally i only use DVDshrink as a editing tool to take out junk i don't want and or downsize extras, while leaving the final compression to another tool(DVD2One).

Recently i have wanted to combine 2 episodic DVDs to 1 DVD-R. However at 10 episodes/4 hours total for both, its the most i have ever combined before. So i would like the best quality between the programs i am useing.

Normally i leave final compression to DVD2One for normal compression stuff as it does a nice job, however i hear that DVDshrink with its deep Analyisis&adaptive error compensation produce better results. Problem is,that crap takes FOREVER which is why i have never once used it up till now.

So like the topic title asks, is DVDshrinks Deep analyisis&adaptive error compensation worth the MAJOR time it takes to encode time to encode?

Honestly,i just ran a test encode just to test it with both modes turned on, went to sleep, woke up *6 hours later* and saw that DVDshrink was still busy encodeing with an estimated 3-4 hours left. Crazy. I ended up quiting it out.

My PC is a 2.8Ghz Celeron D with 512MB Ram so it is not a slow comp either.

Using the wrong tool for the task. DVD Shrink only creates still pictures for the junk which still consumes space. Use vobblanker or titlesetblanker to get rid of the junk including warning screens. These two utilities (both freeware) will replace the titleset and only consume 10Kb in space.

It shouldn't take that long. I can compress a whole dvd with both deep analysis and quality enhancements turned on in an hour.

Try re-installing dvd shrink and see if that helps. Ensure you are using version 3.2[/code]

[RottenFoxBreath]

i would just stick to 5 eps on 1 dvd,at 4 hours per disc.

[flabob]

wow..5 hrs....that is weird...i use shrink all the time...and it only takes me 15 minuets to encode...and if you cant get 100% and use no comperssion.....then i always use the deep analysis..it does make a big differance...and deep analysis takes 15 minuets also if i use it.. did you try uninstalling your dvd shrink..then reinstalling it with the newest version?

[Super Warrior]

I have the current version DVDshrink.

And RFB, Each DVD is 5 episodes at 2 hours. For both it would be 10 episodes@4 hours total.

DVDshrink is easy for me to use as i can clearly see what i am getting rid of, and it does not take up much filesize. For example getting rid of a 3 minute trailor will usually result in a 0.15MB size,so it still takes up space but nothing to be concerned about.

I downloaded the titlesetblanker thingy, but there is no option to play/preview the set i am blanking. Leaving me pretty much blind and unknowing if i am blanking out the wrong thing.

Also when i go to downsize the merged DVDs, its about 12GBs that i'm bringing down to 1 DVD-R. Maybe thats why it takes long,i dunno. On regular settings DVDshrink is fine but with those 2 extra features turned on, then it takes a LOOOOOONG time. DVDshrink's help section even states that it would take a powerful CPU and much longer to encode that way....

Hmm. I just did "The Aviator" (2:45min movie) using a 2.1Ghz 1Gig Ram XP system. Analysis took like 90 mins and shrinking took 2 hours or so.

Are you guys sure they haven't authored some discs to somehow make them harder to backup?

Seems to me some newer movies are taking longer then usual to back up.

[MeDiCo_BrUjO]

Everybody has answered things about the encoding time & speed, but nobody actually answered Super Warrior's question, is the time DVDShrink takes (10 hours - 1 hour - whatever) worthy?

I myself just do the deep analisys and think that the results are just fine, BUT last week I was backing up Wrestlemania XXI and I found that the results were unsatisfactory. I did the backup again and this time I checked error compensation too... God it took it's time, and I found that the results were indeed better.

These are actually old DVDs i am combineing. I already did so with DVD2One which did not take nearly as long, but DVD2One does not use any of that advanced crap that i'd be looking to make use of with DVDshrink.

I already did a test downsizeing with DVD2One. End quality with 4 hours on 1 disc, was decent SVCD/VHS-looking which is ok for me, but could have been better.I would not mind getting better if it was worth the time.

As for doing it with DVDshrink-- As i said i ended up quitting before the process was finished because it was taking forever. On top of that the damn program would not allow me to downsize to 4.36GB but instead, the lowest it would let me do was like 5.45GB.

So assuming its worth the time to encode&compress with those features turned on, i would end up haveing to do it AGAIN after the first time around and...yikes....

I go to school everyday and work a job btw, so i don't have the patience or time to mess around and experiment with this stuff forever like i used too.

[henry_nettles]

The first thing I do is throw away ALL of the extras, using the reauthor mode in DVDShrink. If I still need more than 10% compression, then I use the Deep Analysis mode. On an Athlon XP 2400 mobile cpu, overclocked to 2.3 ghz (slightly faster than an AMD Athlon XP3200+), I have never seen the process take more than one hour.

The motherboard, cpu, heat sink/fan, and 512 megs of PC3200 memory cost me less than $200, used.

[slacker]

It is absolutely worth going through deep analysis AND maximum smoothness IMHO.

Why smoothness? Why not Maximum sharpness? And does it take a long time for you as well?

[Noahtuck]

If i am compressing a movie only, i don't use it if it's 70-100 %

Now i had 2 movie's only that were down to 60% and i used both deep analysis & maximum sharpness and it only took somewhere around 60-90 minutes.
they were both about 3 hour movies, and the result was great!!!

Something must be choking up to make it take 6-10 hours

[jimmalenko]

I think Deep Analysis and AEC ARE worth the time. It has never taken me more than a hour though.



... but trying to squeeze 12GB into 4.37GB ???

That's like trying to rake diarrhea up a hill ...



You'd be much better off IMO lowering the framesize and re-encoding. Transcoders aren't designed to be miracle workers ...

[guns1inger]

I agree with Jimmalenko. I use Shrink for reauthoring, and for small reductions (sub 90%). I always use deep analysis and AEC if reducing. If I have to Shrink more than that, then I use shrink to reauthor, and DVD Rebuilder with CCE to re-encode to a smaller size. I tried vobblanker, but found it's output to be unreadable by either shrink or DVD RB.

[jtoolman2000]

Why not Maximum sharpness?

Because you do not want to enphasize any and all artifacts you will get compressing so much.

Even with my old Gateway 2400 p4 and i gig pc2700 ram I can do a full backup with evrything and all CRAP options ( as you put it ) including to burn with DVD decrypter and I get my burned disk in less than 1-1:30 hours.

I will NEVER try to back up 10-12 gigs to one disk. The MAX Shrink can do is one full DVD9 to a DVD5 otherwizwe you will need to shrink twice and you results will definitely suck.

[archaeo]

Problem is, that crap takes FOREVER

You get what you 'wait' for. If you wanty the best quality, it takes time for the programs to process the images to best decide how to reallocate bitrate. I don't even use transcoders for anything under 90% compression or so, I go strictly with encoders like HC, or CCE basic. And these take even more time in most cases. It has proven to be worth the wait.

[pjcrown]

I often shrink videos at 60% compression with DVD Shrink especially if they are wide screen. If you think about it, almost half the video is black in wide screen videos, so shrink can do a great job. I always use deep analysis and AEC sharp and get great results.

Same here, I definitely think DVDshrink is worth the wait, although like many others here I only have to wait 1-1.5 hours for it to finish.
I believe you have to wait if you want quality output.

Damn. I find it incredabley hard to believe you guys can process with extra features turned on in just a few hours.

What could possibley be causeing my 5-8 hour encode time? When i tried it i used Deep analyisis and sharp(default) AEC by the way.

[HARRYSPADGE]

It's probably got something to do with the large amount of video you are trying to compress, as Jimmalenko pointed out in an earlier post.

Try backing up a normal movie DVD and I'll bet you you'll see the time drop to what we have been achieving.

[Denvers Dawgs]

I'm not trying ot hijack Super Warrior's thread, but what is the Analysis & compensation process. What exactly is it and what does it do? What is AEC sharp? maximum smoothness? And how/when would I use them and the Deep Analysis?

[lordsmurf]

Sometimes.

[ricoman]

Sometimes.

[Denvers Dawgs]

LOL...thanks LS......

[Super Warrior]

Bahh on DVDshrink! Before when the combined filesize was at 12GBs, it would NEVER allow a downsize all the way down to 4.36. After reduceing the 12GB to 8GBs with DVD2One and trying again, it still will not allow 4.36 but instead will only bring it down to about 5.50GB. Making me have to repeat it twice through...

Anyway blehh...

Instead of combineing the two, i'll just put them separetly as normal. Its for the best as the excellent quality is retained, whereas cramming 4 hours to 1 disc would have been signifigantly lower,even with the dvdshrink stuff probabley.

[ricoman]

Have you tried RatDVD? It's new and supposed to get good quality with very high compression.

[guns1inger]

almost half the video is black in wide screen videos

Actually, unless the disk is 4:3 letterboxed, most of the screen is video. If your disk is "widescreen enhanced", "16:9", "Anamorphic" etc, then your player is adding the black bars by compressing the image. There is as much data on a 16:9 1.78:1 movie as there is on a 4:3 fullscreen disk. Even a 16:9 disk with a 2.35:1 AR movie fills better than 50% of the screen area with movie.

[Fandim]

Maybe I'm wierd, but I ALWAYS use deep analysis and "sharp" (move it to smooth if compression is beyond 65%, though). Even for 90%. <shrug>
